langflow-mcp-server

npm version npm downloads GitHub release License: MIT Tests MCP Badge

A Model Context Protocol (MCP) server that provides AI assistants with comprehensive access to Langflow workflow automation platform.

Overview

langflow-mcp-server serves as a bridge between Langflow's workflow automation platform and AI models, enabling them to understand and work with Langflow flows effectively.

API Compatibility: This server is built on the Langflow API documentation and supports Langflow API version 1.11.5. The 1.11.x API family adds A2A (Agent-to-Agent) endpoints, v2 workflow human-in-the-loop lifecycle (pending/resume/events) plus public execution, and external trusted-JWT / JIT-provisioning auth (config-only, no new tools). Langflow 1.11.5 keeps the route surface used by this server and includes upstream security hardening; this release targets that latest 1.11.x patch.

Versioning: From 4.10.0 onward, the npm minor version mirrors the supported Langflow minor — langflow-mcp-server@4.<langflow_minor>.x targets Langflow 1.<langflow_minor>.x (so 4.11.x ↔ Langflow 1.11.x, 4.10.x ↔ Langflow 1.10.x). The patch component is used for fixes within the same Langflow minor.

Consolidated Tools Mode

Consolidated Tools Mode is an architecture that groups the 220 individual tools into 28 action-based meta-tools. This significantly reduces token usage and improves AI assistant context management.

Claude Desktop Setup

Add to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "langflow": {
      "command": "npx",
      "args": ["-y", "langflow-mcp-server"],
      "env": {
        "LANGFLOW_BASE_URL": "http://localhost:7860",
        "LANGFLOW_API_KEY": "your-api-key-here",
        "LANGFLOW_CONSOLIDATED_TOOLS": "true",
        "MCP_MODE": "stdio",

Restart Claude Desktop after updating configuration.

Claude Code, Codex, and other MCP hosts

The server supports both standard MCP transports: local stdio and remote Streamable HTTP. MCP clients use the same tool and schema surface regardless of transport. Use stdio when the host can launch a local process; use HTTP when the server runs as a separately deployed service.

Codex CLI — local stdio

codex mcp add langflow \
  --env LANGFLOW_BASE_URL=http://localhost:7860 \
  --env LANGFLOW_API_KEY=your-api-key-here \
  -- npx -y langflow-mcp-server

Claude Code — local stdio

claude mcp add langflow \
  -e LANGFLOW_BASE_URL=http://localhost:7860 \
  -e LANGFLOW_API_KEY=your-api-key-here \
  -- npx -y langflow-mcp-server

Remote Streamable HTTP

Start the server with an explicit bearer token when binding outside the local machine. HOST=127.0.0.1 is the secure default; use HOST=0.0.0.0 only with authentication and a TLS-terminating reverse proxy.

MCP_MODE=http \
HOST=0.0.0.0 \
PORT=3000 \
AUTH_TOKEN=replace-with-a-long-random-token \
LANGFLOW_BASE_URL=https://langflow.example.com \
LANGFLOW_API_KEY=your-api-key-here \
npx -y langflow-mcp-server

The MCP endpoint is https://your-host.example/mcp; the health endpoint is https://your-host.example/health. For browser-based callers, set MCP_ALLOWED_ORIGINS to a comma-separated list of exact HTTPS origins. Wildcard origins are rejected.

Codex CLI can keep the bearer token in an environment variable:

export LANGFLOW_MCP_TOKEN='set-this-in-your-shell'
codex mcp add langflow-remote \
  --url https://your-host.example/mcp \
  --bearer-token-env-var LANGFLOW_MCP_TOKEN

The environment variable must be present whenever Codex starts or reconnects to this server.

Claude Code accepts the same Streamable HTTP endpoint:

export LANGFLOW_MCP_TOKEN='set-this-in-your-shell'
claude mcp add --transport http --scope user \
  --header "Authorization: Bearer ${LANGFLOW_MCP_TOKEN}" \
  langflow-remote https://your-host.example/mcp

This stores the header in the Claude MCP configuration; keep that configuration outside source control. Hosts such as Cloud Code, Gemini clients, and other MCP-compatible tools can use the same /mcp endpoint when they support Streamable HTTP; their configuration syntax is host-specific and has not been claimed as an end-to-end test in this repository.

Docker Deployment

The MCP server can be run in a Docker container for easier deployment and isolation.

Available MCP Tools

Once connected, Claude can use:

  • Standard mode: 220 individual tools

  • Consolidated mode: 28 action-based tools (recommended for reduced token usage)

Note: Raw Langflow transport endpoints (/api/mcp/*) and doc-rendering endpoints (/docs, /redoc, /openapi.json) are intentionally not exposed as tools — they are protocol/transport surfaces, not data operations.

External / Trusted-JWT Authentication (Langflow 1.11.x)

Langflow 1.11.x adds external trusted-JWT / JIT-provisioning authentication. This is controlled entirely by the Langflow server environment and adds no MCP tools: EXTERNAL_AUTH_ENABLED, EXTERNAL_AUTH_TOKEN_HEADER/EXTERNAL_AUTH_TOKEN_COOKIE, EXTERNAL_AUTH_JWKS_URL, EXTERNAL_AUTH_ISSUER/EXTERNAL_AUTH_AUDIENCE/EXTERNAL_AUTH_ALGORITHMS, EXTERNAL_AUTH_*_CLAIM, and EXTERNAL_AUTH_ACCESS_CEILING_*. The MCP client keeps using its API key / Bearer token as before.

Available Tools

216 tools
activate_flow_versionA

Activate a specific saved version of a flow, making it the current version. Optionally save the current state as a draft first.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID (UUID)
save_draftNoSave current state as draft before activating
version_idYesVersion ID to activate

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the primary behavioral traits: activation changes the current version and optionally saves a draft. No annotations are provided, so the description carries the full burden. It could mention side effects or required permissions for completeness.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with two clauses, no wasted words, and front-loaded with the main action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core functionality and optional behavior. Without an output schema, it could mention return values, but the context is sufficient for an activation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for all 3 parameters. The description adds minimal value beyond the schema, only implying the optional draft save. Baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Activate' and the resource 'specific saved version of a flow', with the outcome of making it current. It distinguishes from sibling tools like get_flow_version and delete_flow_version.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for using the tool (activating a version and optionally saving a draft), but does not explicitly differentiate from alternatives or state when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

add_authz_team_memberB

Add a user to an authorization team.

ParametersJSON Schema
NameRequiredDescriptionDefault
sourceNoMembership source: manual or sso
team_idYesTeam ID
user_idYesUser ID to add

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description only states the action 'Add' but does not disclose any behavioral traits beyond mutation, such as idempotency, required permissions, side effects, or error conditions. With no annotations present, the description carries full burden for transparency but is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single 7-word sentence, extremely concise and front-loaded. Every word is necessary, and it avoids any redundant or extraneous information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple add operation, the description provides the core purpose but lacks context about authorization team semantics, error handling, or return values. Given no output schema and simple parameters, completeness is adequate but leaves gaps for an agent to fully understand the operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with all three parameters described. The tool description adds no extra meaning beyond the schema, such as clarifying the source of team_id or user_id. Per guidelines, baseline 3 is appropriate when schema coverage is high.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Add a user to an authorization team' clearly states the verb (add) and resource (user to authorization team), distinguishing it from siblings like remove_authz_team_member. However, it is minimal and does not elaborate on the specific context of 'authorization team', though the name and description together are sufficient for basic understanding.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives, such as create_authz_role_assignment or other team management tools. There are no prerequisites or conditions mentioned, leaving the agent to infer usage without explicit context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

agentic_assistC

Request agentic assistance for building or editing a flow component.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID
providerNoOptional provider
field_nameNoOptional target field name
model_nameNoOptional model name
session_idNoOptional session ID
input_valueNoUser input/instruction
max_retriesNoOptional max retries
component_idNoOptional target component ID

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. It does not disclose whether the operation is asynchronous, what side effects occur (e.g., modifies the flow), or any required permissions. The term 'request' is ambiguous.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence, 13 words, which is concise. However, for a tool with 8 parameters, a bit more structure (e.g., listing key aspects) would improve readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description lacks critical context: no output schema, no mention of return value or behavior upon failure, and no explanation of how 'assistance' is provided. For a tool with this many parameters, the description is inadequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Parameter descriptions in schema cover 100% of properties. The tool description adds minimal context (e.g., 'building or editing a flow component') but does not elaborate on how parameters like `input_value` or `session_id` are used together.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the tool requests agentic assistance for building or editing a flow component, which is a specific verb-resource pair. It somewhat distinguishes from sibling tools like `agentic_execute` or `agentic_check_config` by focusing on building/editing, but could be more precise.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives such as `agentic_execute` or `run_flow`. There is no mention of prerequisites, conditions, or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

agentic_check_configA

Check whether the agentic assistant is configured and available.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description must disclose behavior. It only states it's a check (likely read-only) but does not mention side effects, permissions, or what happens if the assistant is not configured. Missing critical context for a check tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with no redundancy. Every word contributes to the purpose. Highly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description lacks information about return values or output format. Since there is no output schema, the description should hint at what the agent can expect (e.g., boolean status). This gap reduces completeness for a tool that needs decision-making feedback.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has no parameters (0 params, 100% schema coverage). Description correctly adds no param info because none exist. As per rules, baseline is 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Check' and the resource 'whether the agentic assistant is configured and available'. It distinguishes from sibling tools like 'agentic_assist' and 'agentic_execute' which perform actions, not checks.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. With many sibling tools that may perform similar checks (e.g., health_check), the description should suggest appropriate contexts or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

agentic_executeC

Execute an agentic assistant flow by name with the given assist request fields.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID
providerNoOptional provider
flow_nameYesAgentic flow name to execute
field_nameNoOptional target field name
model_nameNoOptional model name
session_idNoOptional session ID
input_valueNoUser input/instruction
max_retriesNoOptional max retries
component_idNoOptional target component ID

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. Description does not disclose any behavioral traits like side effects, authentication requirements, rate limits, or execution behavior. For a mutation tool that executes a flow, more transparency is needed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence of 15 words, no wasted text. However, it is minimal and lacks structure like bullet points or sections. Could be improved but acceptable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has 9 parameters and no output schema, yet the description is extremely brief. It doesn't explain return values, error conditions, parameter interactions, or execution flow. Under-specified for a complex agentic execution tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. Description adds no extra meaning beyond schema; it mentions 'assist request fields' but doesn't elaborate. Parameter descriptions are terse but functional.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Describes executing an agentic assistant flow by name with assist request fields. Clear verb and resource, but does not explicitly differentiate from sibling tools like 'agentic_assist' or 'run_flow_advanced'. The word 'agentic' provides context.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. No prerequisites, when-not-to-use, or usage context provided. Simply states what it does.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

auto_loginA

Automatically login with stored credentials or session. Returns access token if auto-login is configured and enabled.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4.3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears the burden of disclosure. It reveals that the tool returns an access token only under a certain condition, implying it may do nothing or fail otherwise. However, it does not specify the behavior when auto-login is not configured (e.g., error, null).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is front-loaded with the action and condition. It is concise with no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no parameters, no output schema, and no annotations, the description is mostly complete. It could improve by stating the behavior when auto-login is not configured, but it adequately conveys the core functionality.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are no parameters, so the description does not need to add parameter meaning. The schema coverage is 100% (empty), and the description suffices.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('automatically login') and the outcome ('returns access token'), including the condition ('if auto-login is configured and enabled'). It distinguishes from siblings like 'login', 'refresh_token', and 'logout'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides a clear condition for use ('if auto-login is configured and enabled'), indicating when the tool is appropriate. It does not explicitly state when not to use or name alternatives, but the context is clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

batch_create_flowsA

Create multiple flows in a single batch operation. More efficient than creating flows individually. Accepts array of flow objects.

ParametersJSON Schema
NameRequiredDescriptionDefault
flowsYesArray of flow objects to create

TDQS

A3.7/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must compensate but fails to disclose important behaviors: whether the operation is atomic, what happens on partial failure, authentication requirements, rate limits, or return value. The mention of 'batch operation' is minimal extra context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with no fluff. Front-loaded with the primary action and benefit, followed by parameter clarification. Every word serves a purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a batch creation tool with no output schema, the description is adequate but incomplete: it does not mention what is returned (e.g., created flow IDs), error handling, or whether flows are created sequentially or in parallel. Given the simplicity of parameters, this is a notable gap but not critical.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage for the single 'flows' parameter, describing each field (data, name, folder_id, description). The description adds only 'Accepts array of flow objects,' which is already clear from the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool creates multiple flows in a batch, using specific verb 'create' and resource 'flows', and distinguishes from individual creation by emphasizing batch efficiency. It leaves no ambiguity about the tool's purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states it is 'More efficient than creating flows individually,' implying its use when creating multiple flows. However, it does not specify when not to use it (e.g., for a single flow) or provide explicit alternatives, though the sibling tool 'create_flow' is implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

batch_delete_files_v2B

Batch delete multiple user-scoped files via /api/v2/files by their IDs.

ParametersJSON Schema
NameRequiredDescriptionDefault
file_idsYesFile IDs to delete

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided; description only states the destructive operation without disclosing behavioral traits (e.g., idempotency, atomicity, error handling, rate limits). Minimal transparency for a batch operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, 12 words, no fluff. Efficiently communicates purpose, scope, and method. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a simple one-parameter batch delete, but lacks details on failure behavior, results, permissions, or any nuances that differentiate it from sibling tools. With no output schema, more context would be beneficial.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers 100% of the parameter documentation. The description adds the 'user-scoped' context and endpoint, but the parameter meaning is fully explicit in the schema. Baseline 3 suffices.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (batch delete), the resource (multiple user-scoped files by IDs), and the endpoint (/api/v2/files). It effectively distinguishes from siblings like delete_file (single file) and delete_all_files_v2 (delete all files).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., delete_file_v2, delete_all_files_v2). Lacks mentions of prerequisites, constraints, or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

batch_download_files_v2B

Batch download multiple user-scoped files via /api/v2/files by their IDs.

ParametersJSON Schema
NameRequiredDescriptionDefault
file_idsYesFile IDs to download

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Only says 'batch download via API' but does not disclose return format (e.g., zip, URLs), synchronicity, or behavior on invalid IDs. Agent lacks key behavioral cues.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with no extraneous words. Efficiently conveys core action and resource.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema. Description does not hint at response format or how to handle results. With many sibling tools, lacks integration context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

One parameter (file_ids) with full schema description coverage (100%). Description adds no semantic info beyond schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description specifies verb 'batch download', resource 'user-scoped files', endpoint '/api/v2/files', and input 'by their IDs'. It clearly distinguishes from sibling tools like download_file (single) and list_files_v2 (listing).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this vs. alternatives like download_file. No mention of limits (e.g., max file count), prerequisites, or error handling (e.g., partial success).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

build_flowA

Compile and validate a flow, returning job ID for asynchronous status monitoring.

Purpose: Build and validate a flow's component graph, ensuring all nodes are properly configured and connected. Essential prerequisite for flow execution - detects configuration errors, validates component parameters, and prepares the flow for running. Returns job_id for tracking build progress asynchronously.

Parameters:

  • flow_id (required, UUID string): Flow identifier to build and validate

  • inputs (optional, object): Input values to use during build validation (key: input_name, value: test_data)

  • data (optional, object): Flow configuration override (use to build modified version without updating flow)

  • files (optional, array of strings): File paths to include in build context

  • stop_component_id (optional, string): Component ID where build should stop (useful for partial validation)

  • start_component_id (optional, string): Component ID where build should start (skip earlier components)

  • log_builds (optional, boolean, default: true): Enable detailed build logging for debugging

  • flow_name (optional, string): Override flow name during build (doesn't affect saved flow)

  • event_delivery (optional, string, default: "polling"): Delivery mode - "polling" (recommended), "streaming", or "direct"

Returns: BuildFlowResponse object containing:

  • job_id (UUID): Unique build job identifier for status polling via get_build_status

Usage Examples:

  1. Basic build: { flow_id: "550e8400-e29b-41d4-a716-446655440000" }

  2. Build with logging: { flow_id: "flow-uuid", log_builds: true }

  3. Build with test inputs: { flow_id: "flow-uuid", inputs: { "user_message": "test" } }

  4. Partial build: { flow_id: "flow-uuid", start_component_id: "node-1", stop_component_id: "node-5" }

  5. Streaming events: { flow_id: "flow-uuid", event_delivery: "streaming" }

Best Practices:

  • Always build flow before first execution to catch configuration errors early

  • Use polling event_delivery for reliable status tracking in production

  • Enable log_builds during development for detailed error diagnostics

  • Rebuild after any flow modifications (nodes, edges, parameters)

  • Monitor build status with get_build_status using returned job_id

  • Use partial builds (start/stop component) for faster validation of specific sections

  • Validate inputs during build to ensure flow accepts expected data format

  • Cache successful build status to avoid unnecessary rebuilds

Common Errors:

  • "Flow not found": flow_id doesn't exist (verify with list_flows or get_flow)

  • "Invalid flow configuration": Flow has disconnected nodes or missing required parameters

  • "Component validation failed": Node configuration is invalid (check component settings in Langflow UI)

  • "Missing required component parameters": Required fields not set on components

  • "Build timeout": Complex flow took too long; simplify or optimize component chain

  • "Invalid component ID": start_component_id or stop_component_id doesn't exist in flow

  • "Circular dependency detected": Flow has loop in node connections

Related Tools:

  • get_build_status: Poll build completion and retrieve validation results using job_id

  • run_flow: Execute flow after successful build

  • get_flow: Inspect flow structure before building

  • cancel_build: Stop long-running build job

  • update_flow: Fix configuration errors found during build

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must fully disclose behavior. It explains that the tool returns a job_id for async monitoring, performs validation, and supports partial builds via start/stop_component_id. It also mentions potential build timeout. However, it does not explicitly state whether the operation is read-only or modifies state, though it seems to prepare the flow without permanent changes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections: Purpose, Parameters, Returns, Usage Examples, Best Practices, Common Errors, Related Tools. The core purpose is stated upfront. While it is verbose and sometimes repeats schema information, each section contributes useful information and the organization is clear.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (9 parameters, nested objects, async behavior), the description is complete. It covers the purpose, each parameter's role, return value, examples, best practices, common errors, and related tools. Even without an output schema, it adequately describes the return object (job_id).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents each parameter. The description enriches this by explaining the purpose of each parameter (e.g., 'stop_component_id: Component ID where build should stop (useful for partial validation)') and provides usage examples that demonstrate parameter combinations. This adds value beyond the schema definitions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Compile and validate a flow, returning job ID for asynchronous status monitoring.' It uses specific verbs (compile, validate) and identifies the resource (flow) and output (job ID). This distinguishes it from sibling tools like run_flow and get_build_status.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states it is an 'Essential prerequisite for flow execution' and provides a 'Best Practices' section with clear guidance (e.g., 'Always build flow before first execution'). Also includes 'Common Errors' to help avoid misuse and lists related tools like get_build_status and run_flow.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

build_verticesA

⚠️ DEPRECATED: This endpoint is deprecated in Langflow API 1.6.4 and will be removed in a future version. Use "build_flow" tool instead with start_component_id/stop_component_id for partial builds.

Get vertex build order for a flow. Retrieves the ordered list of vertex IDs representing the build execution sequence. Useful for understanding flow component dependencies, optimizing build performance, and debugging build order issues. Supports partial builds with start/stop component IDs.

ParametersJSON Schema
NameRequiredDescriptionDefault
dataNoOptional flow data override for build
flow_idYesFlow ID (UUID) to retrieve vertex build order for
stop_component_idNoOptional component ID to stop build at
start_component_idNoOptional component ID to start build from

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Although no annotations are provided, the description implies a read-only operation by using verbs like 'Retrieves' and 'Get'. It also transparently notes deprecation and planned removal. However, it does not explicitly state lack of side effects or authorization requirements, which would be ideal for full transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is somewhat verbose but each sentence adds value. The deprecation warning is placed at the beginning for importance, and the core purpose follows. It could be slightly more concise, but the structure effectively prioritizes critical information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the main functionality, use cases, and the output format ('ordered list of vertex IDs'). Without an output schema, it adequately describes what the tool returns. However, it does not mention error conditions or performance implications, leaving some minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All 4 parameters are described in the schema (100% coverage). The description adds some context about partial builds involving start/stop_component_id, but this largely repeats schema info. It does not provide additional syntax, constraints, or parameter-specific guidance beyond what the schema already offers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Get vertex build order for a flow.' It specifies the action (retrieve) and resource (vertex build order), and distinguishes from the sibling tool 'build_flow' by recommending it as a replacement for partial builds.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly tells when not to use this tool (deprecated) and provides the alternative ('Use build_flow tool instead'). It also explains when the tool is useful (understanding dependencies, optimizing performance, debugging) and mentions partial build support via start/stop component IDs.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

bulk_delete_knowledge_basesB

Delete multiple knowledge bases at once. Useful for batch cleanup operations.

ParametersJSON Schema
NameRequiredDescriptionDefault
kb_namesYesArray of knowledge base names to delete

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must fully disclose behavioral traits. It only states 'delete multiple knowledge bases at once' without mentioning irreversibility, error handling (e.g., partial failures), permissions required, or impact on associated data.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with no wasted words; front-loaded with the core action and followed by a clear usage context.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive batch operation, the description lacks critical context: no warning about potential data loss, limits on batch size, behavior on invalid names, or confirmation steps. It is inadequate for safe and correct usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema documentation coverage is 100% (the only parameter 'kb_names' is described as 'Array of knowledge base names to delete'). The description adds no additional meaning beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the verb 'Delete', the object 'multiple knowledge bases', and the scope 'at once. Useful for batch cleanup operations.' This clearly distinguishes it from the sibling single-delete tool 'delete_knowledge_base'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description suggests batch cleanup as a use case, implying when to use it over individual deletes. However, it does not provide when-not-to-use guidance or mention prerequisites, limits, or risks.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

cancel_buildB

Cancel a running build job. Stops the build process for the specified job.

ParametersJSON Schema
NameRequiredDescriptionDefault
job_idYesBuild job ID to cancel

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It indicates a mutation action ('stops the build process') but does not disclose side effects (e.g., status changes, resource cleanup, behavior for invalid/completed jobs).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no fluff, front-loaded purpose. Every word adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter tool, the description covers the core purpose but lacks details on error handling, return values, and edge cases.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds no meaning beyond the input schema, which already documents job_id as 'Build job ID to cancel'. With 100% schema coverage, the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (cancel), resource (build job), and effect (stops the build process). It distinguishes from creating or monitoring builds, but does not explicitly differentiate from deleting build records (e.g., delete_monitor_builds).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no conditions. It does not mention that the job must be running or that cancellation is irreversible.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

cancel_knowledge_base_ingestA

Cancel an in-progress knowledge base ingestion job.

ParametersJSON Schema
NameRequiredDescriptionDefault
kb_nameYesKnowledge base name

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden but only states the basic action. It does not disclose side effects, permissions, or behavior when called on a non-ingesting KB.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single concise sentence with no wasted words, front-loading the essential action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple cancellation tool with one parameter and no output schema, the description is minimally viable but lacks details on prerequisites and error conditions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% so baseline is 3. Description adds no additional meaning beyond the schema's parameter description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action 'Cancel' and the resource 'in-progress knowledge base ingestion job', distinguishing it from siblings like 'ingest_knowledge_base' and 'delete_knowledge_base'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool is meant for cancelling an ongoing ingestion but provides no explicit guidance on when to use it versus alternatives or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

check_memory_base_mismatchB

Check a memory base for configuration or embedding mismatches.

ParametersJSON Schema
NameRequiredDescriptionDefault
memory_base_idYesMemory base ID

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavior. It only states the action without explaining what the check entails (e.g., whether it mutates data, requires specific permissions, or returns a report). The agent cannot infer side effects or outputs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, short sentence that efficiently conveys the tool's purpose. No redundant or extraneous text. Front-loaded with key verb and object.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (1 parameter, no output schema, no annotations), the description should at least hint at the output format (e.g., returns a boolean or list of mismatches). The current description leaves the agent guessing about what to do with the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter (memory_base_id) is fully described in the input schema (100% coverage). The tool description adds no additional meaning; it just restates the fact that the parameter identifies the memory base. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Check') and resource ('a memory base') and clearly specifies two types of mismatches (configuration or embedding). This distinguishes it from sibling tools like create_memory_base or get_memory_base.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives, no prerequisites, and no mention of expected outcomes. The description does not help an agent decide between this and other memory base tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

check_storeA

Check if the Langflow component store is enabled and accessible.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description implies a read-only check, but does not disclose what happens if the store is not enabled, the return format, or any side effects. For a simple check tool, this is adequate but minimally transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is concise and to the point. It is appropriately sized for the tool's simplicity, though it could be slightly more structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has no parameters, no output schema, and low complexity, the description is complete enough to convey its purpose. However, it could mention the return value or behavior for completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters, so the description adds no parameter info. According to guidelines, 0 params earns a baseline of 4, and the description does not need to add meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool checks if the Langflow component store is enabled and accessible, using a specific verb ('Check') and resource ('Langflow component store'). It distinguishes from the sibling tool 'check_store_api_key' which checks the API key.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives, such as when to check the store vs. checking the API key. No context or exclusions are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

check_store_api_keyB

Validate a store API key for accessing the Langflow component store.

ParametersJSON Schema
NameRequiredDescriptionDefault
api_keyYesStore API key to validate

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It only says 'validate' but does not disclose what happens on success/failure, any side effects, or whether it is read-only. Minimal transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that immediately states the purpose, with no unnecessary words or fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple validation tool with one parameter and no output schema, the description is adequate but could be improved by specifying the return value (e.g., boolean or error).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the description repeats the schema's parameter description without adding extra details like format or restrictions. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Validate') and the resource ('store API key'), and it distinguishes from sibling tools like 'save_store_api_key' which has a different purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives, nor any prerequisites or conditions for use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_api_keyA

Create a new API key with a specified name. Returns the created API key object including the key value (only shown once).

ParametersJSON Schema
NameRequiredDescriptionDefault
nameYesName/label for the API key

TDQS

A4.1/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so the description bears full responsibility. It discloses that the API key value is only shown once in the response, which is critical behavioral information. It does not cover prerequisites or side effects, but the tool is simple and non-destructive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences efficiently convey the essential information: what the tool does and a notable behavior (key shown once). No unnecessary words or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple creation tool with a single parameter and no output schema, the description covers the required input, the return value, and a key behavioral note (one-time key display). It is fully adequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% with a single parameter 'name' described as 'Name/label for the API key'. The description adds no additional meaning beyond what the schema provides, so a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (create) and the resource (API key). It identifies the required input (name) and the return value (key value shown once), distinguishing it from sibling tools like list_api_keys and delete_api_key.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives. The purpose is implicitly clear, but the description does not mention when not to use it or mention related tools for listing or deleting keys.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_authz_roleA

Create an authorization role with optional permissions and a parent role.

ParametersJSON Schema
NameRequiredDescriptionDefault
nameYesRole name
descriptionNoRole description
permissionsNoPermission identifiers
parent_role_idNoParent role ID for inheritance

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so description must disclose behavior. It only states creation with optional fields but omits idempotency, error conditions, auth requirements, or return value. Insufficient for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no verbosity, every word contributes. Front-loaded with verb and resource.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema; description fails to mention return value or side effects. At minimum should state 'returns the created role'. Adequate for a simple creation tool but incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 100% description coverage. Description summarizes but adds no new meaning beyond 'optional permissions and parent role'. Baseline 3 is appropriate as schema does the work.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states verb 'create', resource 'authorization role', and optional parameters. Distinguishes from sibling tools like update_authz_role and delete_authz_role.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit when-to-use or alternatives provided. Implies usage but lacks guidance on when not to use or comparison with related tools like create_authz_role_assignment.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_authz_role_assignmentB

Assign a role to a user, optionally scoped to a domain.

ParametersJSON Schema
NameRequiredDescriptionDefault
role_idYesRole ID
user_idYesUser ID
domain_idNoDomain ID for the scope
domain_typeNoDomain type: global, org, workspace, or project

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavioral traits. It only states the basic action. Missing details: idempotency (can the same assignment be made twice?), what happens if the user already has the role, required permissions, and whether the assignment overwrites or adds. The optional domain scope is mentioned but not elaborated (e.g., whether domain_id is required when domain_type is set).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence: 'Assign a role to a user, optionally scoped to a domain.' It is concise and contains no wasted words, directly stating the tool's function.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has 4 parameters and no output schema. The description is incomplete for safe usage: it does not explain that both user and role must already exist, whether the assignment is idempotent, what are valid domain types, or error conditions. Given no annotations, the description should provide more behavioral context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description adds no extra semantic value beyond the schema. It reiterates the optional domain scope, but the schema already describes the parameters with similar wording. No additional context about parameter relationships or validation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action: 'Assign a role to a user, optionally scoped to a domain.' It uses a specific verb ('assign') and identifies the resource ('role to a user'), distinguishing it from sibling tools like 'create_authz_role' (which creates a role definition) and 'delete_authz_role_assignment'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives, such as when to scope by domain or when not to. No mention of prerequisites (e.g., user and role must exist) or typical use cases. The description lacks any 'when-to-use' or 'when-not-to-use' context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_authz_shareB

Share a resource with a scope and optional target and permission level.

ParametersJSON Schema
NameRequiredDescriptionDefault
scopeYesShare scope: private, team, user, or public
target_idNoTarget ID for the share
resource_idYesResource ID to share
resource_typeYesResource type: flow, deployment, project, knowledge_base, variable, or file
permission_levelNoPermission level: read, write, execute, or admin

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears full responsibility. It fails to disclose behavioral traits such as whether it creates a new share, requires specific permissions, or returns the created entity. The description is too terse to inform the agent about side effects or prerequisites.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that front-loads the action and key parameters. It contains no filler, but could be slightly expanded for clarity without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 5 parameters and no output schema, the description should clarify that it creates a new authorization share and differentiate from update/delete siblings. It fails to mention creation or return value, making it incomplete for an agent to understand the full operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All 5 parameters have descriptions in the input schema (100% coverage). The description adds minimal value beyond the schema by noting 'optional target and permission level,' but does not explain relationships or constraints. Baseline 3 as schema carries the load.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's action: 'Share a resource with a scope and optional target and permission level.' It identifies the verb 'share' and the resource, listing the key components. It differentiates from sibling tools like 'create_authz_role' or 'list_authz_shares' by specifying the action and parameters.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives like 'update_authz_share' or 'delete_authz_share'. It lacks prerequisites, when-not-to-use conditions, or context for selection among sibling authorization tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_authz_teamB

Create an authorization team within an administrative domain.

ParametersJSON Schema
NameRequiredDescriptionDefault
adom_nameYesAdministrative domain name
is_activeNoWhether the team is active
team_nameYesTeam name
descriptionNoTeam description

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only states that the tool creates an authorization team but omits critical details such as error handling on duplicates, permissions required, idempotency, or whether it returns the created object. The minimal information is insufficient for safe autonomous invocation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence of 8 words, stating the purpose without any fluff. It is front-loaded with the verb and resource, making it easy to parse. Every word is necessary, and there is no wasted text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 4 parameters, no output schema, and no annotations, the description is too minimal. It fails to explain what an authorization team is, what happens upon creation, or what the return value looks like. Critical information for safe and correct usage is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description does not add any meaning beyond the schema; it merely repeats 'team_name' and 'adom_name' implicitly. No additional context or constraints are provided for parameters like 'is_active' or 'description'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Create an authorization team within an administrative domain' uses a specific verb and resource, clearly indicating the tool's action and scope. It distinguishes this creation tool from sibling operations like list, get, update, and delete, which are separate tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives such as update_authz_team or delete_authz_team. It does not mention prerequisites, context, or exclusions, leaving the agent to infer usage solely from the tool name and description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_custom_componentB

Create a new custom component with Python code. Requires component code, name, and optional description and return_type. Returns created component object.

ParametersJSON Schema

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description must carry the full burden of behavioral disclosure. It states the tool creates a component but fails to mention side effects (e.g., whether it overwrites existing components), error conditions (e.g., name collisions), or any other behavioral traits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that efficiently communicates the core purpose and parameter requirements. It is front-loaded and contains no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the basic operation but lacks details about the return object structure, error handling, or constraints like name uniqueness. Given no output schema and relatively simple parameters, the description is minimally adequate but could be more complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage with descriptions for all four parameters. The description simply lists parameter names without adding new meaning, which meets the baseline but does not exceed it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool creates a new custom component with Python code, listing required and optional parameters. However, it does not differentiate from the sibling tool 'update_custom_component', which could cause confusion about when to use each.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description specifies required parameters (code and name) and optional ones (description, return_type), providing basic usage guidance. However, it lacks context on when to use this tool over alternatives like 'update_custom_component' or any prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_flowA

Create a new Langflow workflow with optional configuration and organization.

Purpose: Initialize a new flow in your Langflow instance. Use this to create workflows from scratch or with predefined structure. The flow can be organized into folders and configured with initial data including nodes, edges, and component settings.

Parameters:

  • name (required, string, max: 255 chars): The display name of the flow (must be unique within folder)

  • description (optional, string): Brief explanation of flow's purpose and functionality

  • data (optional, object): Initial flow configuration containing nodes, edges, and component definitions

  • folder_id (optional, UUID string): ID of parent folder for organization (use list_folders to get valid IDs)

Returns: FlowRead object containing:

  • id (UUID): Newly created flow's unique identifier (save this for future operations)

  • name (string): Flow display name

  • description (string): Flow description

  • folder_id (UUID): Parent folder if specified

  • user_id (UUID): Owner user identifier

  • created_at, updated_at (ISO timestamps): Creation and modification timestamps

  • data (object): Complete flow structure with nodes and edges

Usage Examples:

  1. Create minimal flow: { name: "My Workflow" }

  2. Flow with description: { name: "Data Pipeline", description: "Processes user data" }

  3. Flow in folder: { name: "API Flow", folder_id: "folder-uuid-here" }

  4. Flow with structure: { name: "Chat Bot", data: { nodes: [...], edges: [...] } }

Best Practices:

  • Use descriptive names that indicate flow purpose (e.g., "Customer Onboarding" not "Flow1")

  • Add descriptions to document flow functionality for team collaboration

  • Organize related flows using folder_id for better project management

  • Start with minimal configuration, then use update_flow to add complexity

  • Validate data structure before passing complex flow configurations

Common Errors:

  • "Flow name already exists": Choose a unique name or specify different folder_id

  • "Invalid folder ID": Ensure folder_id is valid UUID from list_folders

  • "Name is required": Must provide name parameter

  • "Data validation failed": Check that data object follows Langflow schema structure

  • "Unauthorized": Verify LANGFLOW_API_KEY is valid

Related Tools:

  • list_flows: View all created flows

  • update_flow: Modify flow after creation

  • get_flow: Retrieve full flow details by ID

  • upload_flow: Import flow from JSON file instead of creating from scratch

  • create_folder: Create folders before organizing flows

ParametersJSON Schema
NameRequiredDescriptionDefault
dataNoOptional flow data/configuration
nameYesThe name of the flow
folder_idNoOptional folder ID to organize the flow
descriptionNoOptional description of the flow

TDQS

A4.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. It discloses creation behavior, return object details, and common error scenarios (e.g., name exists, invalid folder, validation failure, unauthorized). However, it does not explicitly mention idempotency (likely not idempotent) or potential side effects beyond creation. Still, covers key behavioral traits well.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is long but well-structured with clear sections: summary, parameters, returns, usage examples, best practices, common errors, related tools. Front-loaded with purpose. Could trim some redundant examples (e.g., example 1 and 2 are minimal variations), but overall earns its length through comprehensive guidance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool is complex with 4 parameters, nested objects, and many sibling tools. Description covers all aspects: what it does, parameter details including constraints, return object fields (saving the ID for future operations), usage examples, best practices, common errors, and related tools. With no output schema, the detailed return field descriptions are essential and well provided.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but description adds significant value: explains name must be unique within folder and max 255 chars, data object contains nodes/edges/component definitions, folder_id must be a valid UUID from list_folders. Includes four concrete usage examples showing different parameter combinations, clarifying how to use each parameter effectively.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states 'Create a new Langflow workflow with optional configuration and organization.' It specifies the verb 'create', the resource 'Langflow workflow', and distinguishes from siblings like upload_flow (import from JSON) and update_flow (modify after creation). Detailed parameter descriptions and usage examples reinforce purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states when to use ('Initialize a new flow') and provides best practices like using descriptive names, adding descriptions, organizing with folder_id, starting minimal then using update_flow. Related tools section lists alternatives: list_flows, update_flow, upload_flow, create_folder. Common errors section further guides correct usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_flow_eventB

Create a new event for a flow (e.g. deployment or lifecycle event).

ParametersJSON Schema
NameRequiredDescriptionDefault
typeYesEvent type
flow_idYesFlow ID (UUID)
summaryNoOptional event summary

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden. It only states creation of an event, omitting side effects, idempotency, error cases, or required permissions. Insufficient for a mutation operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with clear structure, no extraneous information. Efficiently conveys core purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given low complexity (3 params, no output schema), the description still lacks context about return values, async behavior, or preconditions. Incomplete for a complete understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema descriptions cover 100% of parameters. The description does not add extra meaning beyond noting the purpose; no details on event types, summary format, or constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the action ('Create') and resource ('new event for a flow') with an illustrative example ('e.g. deployment or lifecycle event'). Distinguishes from siblings like get_flow_events (listing) and other create tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use or when not to use this tool. No mention of prerequisites, alternatives, or conditions. The name provides basic intent but no strategic advice.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_flow_versionA

Create a new saved version (snapshot) of a flow. Optionally provide a body with version metadata.

ParametersJSON Schema
NameRequiredDescriptionDefault
bodyNoOptional version creation payload
flow_idYesFlow ID (UUID)

TDQS

A3.7/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description must fully disclose behavior. It notes 'snapshot' implying non-destructive, but fails to mention if it replaces existing versions, concurrency, or authorization needs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, front-loaded with purpose, no unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, so description should explain return value (e.g., created version ID). Also missing prerequisites like permissions. Adequate for basic understanding but incomplete for a creation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for both parameters. Description adds 'version metadata' hint for the body, but no extra details on expected fields inside the body object.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states 'Create a new saved version (snapshot) of a flow'. The verb 'create' and noun 'version' are specific, and it distinguishes from siblings like get_flow_version or delete_flow_version.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies usage when a new snapshot is needed, but does not explicitly mention when to use alternatives like get_flow_version or activate_flow_version. The optional body hint is useful.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_folderA

Create a new folder for organizing flows with optional nested hierarchy.

Purpose: Establish organizational structure in Langflow by creating folders to group related flows. Supports hierarchical organization through nested folders, enabling project-based or team-based flow management. Essential for maintaining organized workspace with many flows.

Parameters:

  • name (required, string, max: 255 chars): Folder display name (should be descriptive and unique)

  • description (optional, string): Purpose and contents description for documentation

  • parent_id (optional, UUID string): Parent folder ID for creating nested subfolder hierarchy (use list_folders to find valid parent IDs)

Returns: FolderRead object containing:

  • id (UUID): Newly created folder's unique identifier (use this as folder_id when creating/organizing flows)

  • name (string): Folder display name

  • description (string): Folder description

  • parent_id (UUID): Parent folder ID if nested, null for root-level folder

  • created_at, updated_at (ISO timestamps): Folder lifecycle timestamps

Usage Examples:

  1. Create root folder: { name: "Production Flows" }

  2. Folder with description: { name: "Customer Services", description: "Customer-facing automation workflows" }

  3. Create nested subfolder: { name: "API Integrations", parent_id: "parent-folder-uuid" }

  4. Project organization: { name: "Q1 2024 Project", description: "First quarter automation initiatives" }

Best Practices:

  • Use descriptive, hierarchical names (e.g., "Marketing/Email Campaigns" structure via nesting)

  • Add descriptions to document folder purpose and ownership

  • Plan folder hierarchy before creation (root categories, then subcategories)

  • Create folders before flows to enable immediate organization

  • Use consistent naming conventions across team (e.g., "Team - Project - Category")

  • Limit nesting depth to 2-3 levels for maintainability

  • Cache created folder IDs for subsequent flow creation operations

Common Errors:

  • "Folder name already exists": Choose unique name or create in different parent folder

  • "Invalid parent folder ID": Ensure parent_id is valid UUID from list_folders

  • "Parent folder not found": parent_id doesn't exist or was deleted

  • "Name is required": Must provide name parameter

  • "Maximum nesting depth exceeded": Too many nested levels (flatten hierarchy)

  • "Circular reference detected": parent_id creates loop in folder structure

Related Tools:

  • list_folders: Browse existing folders before creating new ones

  • update_folder: Modify folder name, description, or move to different parent

  • create_flow: Create flows organized within this folder using returned ID

  • get_folder: Retrieve folder details after creation

  • delete_folder: Remove folder when no longer needed

ParametersJSON Schema
NameRequiredDescriptionDefault
nameYesFolder name (required)
parent_idNoOptional parent folder ID (UUID) for nested folders
descriptionNoOptional folder description

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full responsibility. It discloses the creation behavior, support for nesting, return of FolderRead object with timestamps, and lists common errors like 'Maximum nesting depth exceeded' and 'Circular reference detected'. It does not address authorization or rate limits, but these are not critical for a create operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (Purpose, Parameters, Returns, Examples, Best Practices, Errors, Related Tools). It is somewhat lengthy but each section adds value. The front-loading of purpose and parameters is effective.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the 3 parameters and no output schema, the description compensates thoroughly. It explains the return object in detail, covers common errors, best practices, and related tools. The agent has all necessary information to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% (all three parameters in schema and description). The description adds extra meaning: name has max 255 chars and uniqueness suggestion, parent_id references list_folders, description is for documentation. This exceeds the baseline of 3 by providing valuable context beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the tool's action: 'Create a new folder for organizing flows with optional nested hierarchy.' It clearly identifies the resource (folder), verb (create), and context (organizing flows, supporting hierarchy). This clearly distinguishes it from sibling tools like list_folders, update_folder, and delete_folder, which handle different operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes a 'Related Tools' section that advises using list_folders to find parent IDs and update_folder to modify folders. Best practices guide the agent on planning hierarchy, caching IDs, and consistent naming. Common errors provide troubleshooting guidance. This gives explicit when and when-not guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_knowledge_baseC

Create a new knowledge base with an embedding provider/model and optional column configuration.

ParametersJSON Schema

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description must inform about side effects. It only says 'create' without disclosing persistence, required permissions, idempotency, or return behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Very concise single sentence; however, it omits necessary details that could be added without excess length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Missing critical information: no output schema, no mention of return value, no description of behavior on duplicate names, no prerequisites (e.g., existing project).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents parameters. Description adds no additional meaning beyond repeating the parameter types, but does not clarify column_config structure.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it creates a knowledge base with embedding provider/model and optional column config. However, it does not differentiate from sibling tools like upload_knowledge_base (which may create from file) or ingest_knowledge_base (which populates).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., when to use create vs upload or ingest). No prerequisites or context provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_mcp_serverB

Create an MCP server configuration (stdio command or remote URL based).

ParametersJSON Schema
NameRequiredDescriptionDefault
configYesMCP server config
server_nameYesMCP server name

TDQS

B3.4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must carry the behavioral burden. It indicates a creation operation but lacks details on side effects, permissions, or concurrency behavior. It does clarify the two creation modes (stdio vs remote), which adds some transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that front-loads the key action and resource. No unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and two required parameters (including a nested object), the description is adequate but incomplete. It does not mention return value or error cases, which would be helpful for a creation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% so baseline is 3. The description adds minimal value beyond the schema by hinting at the choice between command+args and url, but does not elaborate on parameter relationships or usage patterns.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool creates an MCP server configuration and mentions it can be stdio or remote URL based, distinguishing it from related list/get/update/delete tools. However, it could be slightly more specific about what exactly is created.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use this tool (to create a new MCP server config) but does not explicitly state when not to use it or mention alternatives like update_mcp_server for modifications.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_memory_baseB

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations are absent, so the description must carry the full burden of behavioral disclosure. It only notes the tool is experimental and hidden, but omits any details about side effects, mutability, permissions, or response behavior. This is insufficient for a creation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: a single sentence that front-loads the core purpose. It includes a useful qualifier ('experimental, hidden in Langflow OpenAPI'). While brief, every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having 9 parameters and no output schema, the description fails to explain what a memory base is, what the parameters control, or what the return value looks like. The context is insufficient for an agent to understand the tool's full capability.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already describes all 9 parameters. The description adds no additional meaning or context beyond what the schema provides (e.g., no explanation of how 'threshold' or 'auto_capture' affect behavior). Baseline 3 applies since the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action 'Create' and the resource 'memory base', and specifies the context 'for a flow'. It distinguishes this tool from sibling tools like list_memory_bases and get_memory_base, which serve different purposes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage guidelines are provided. The description does not indicate when to use this tool over alternatives, nor does it mention prerequisites (e.g., flow existence) or exclusions. The note about being experimental/hidden is about visibility, not usage context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so description bears full burden. Only states 'create'—a mutation—without disclosing side effects, authentication requirements, or constraints (e.g., project limits). Minimal behavioral info.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, no wasted words. Front-loaded with the action verb 'Create'. Efficient and direct.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple creation tool with two parameters and no output schema, description is adequate but lacks details on return value or confirmation of success. Does not specify whether project ID is returned.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. Description adds no additional meaning beyond schema; does not explain allowable formats or use for 'name' or 'description'.

B3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Without annotations, the description should convey behavioral traits, but it only states the endpoint and inputs. No mention of side effects, authentication, rate limits, or implications of parameters like stream or background.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence, but it omits necessary context for a 7-parameter tool. It is not overly verbose, but could better balance brevity and informativeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity and lack of output schema, the description fails to explain return values, error behavior, or how optional parameters affect the call, leaving significant gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

The description uses the specific verb 'Publish' and explicitly names the resource 'new component to the Langflow Store', clearly distinguishing it from sibling tools like 'create_custom_component' or 'list_store_components'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives (e.g., 'create_custom_component'), and no when-not or context cues are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_userC

Create a new Langflow user account.

ParametersJSON Schema
NameRequiredDescriptionDefault
optinsNoOptional opt-in preferences
passwordYesPassword
usernameYesUsername

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavior beyond creation. It lacks details on what happens on duplicate username, whether the user is immediately active, or if any notifications are sent. The description is too minimal for safe agent decision-making.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence, front-loaded with the purpose. No wasted words, appropriate length for a simple operation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations and no output schema, the description should provide more context about success/failure behavior, idempotency, or authentication requirements. It is incomplete for a creation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the description adds no value beyond the schema. The schema already describes username, password, and optins. The description does not explain the optins object, but the high coverage baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Create') and the resource ('a new Langflow user account'), making the tool's purpose unambiguous. However, it does not differentiate from the sibling tool 'register_user', which likely serves a similar role.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like 'register_user', nor are prerequisites (e.g., admin permissions) or potential side effects mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_variableB

Create a new global variable. Variables can be referenced in multiple flows.

ParametersJSON Schema

delete_flowA

Permanently remove a single flow from Langflow instance.

Purpose: Delete flows that are no longer needed, removing obsolete workflows, or cleaning up test/development flows. This operation is destructive and irreversible - deleted flows cannot be recovered unless previously backed up via download_flows.

Parameters:

  • flow_id (required, UUID string): Unique identifier of flow to delete (from list_flows or get_flow)

Returns: Success object containing:

  • success (boolean): true if deletion succeeded

  • message (string): Confirmation message

Usage Examples:

  1. Delete single flow: { flow_id: "550e8400-e29b-41d4-a716-446655440000" }

  2. Remove test flow: { flow_id: "test-flow-uuid" }

Best Practices:

  • Download flow backup with download_flows before deletion if you might need it later

  • Verify flow_id is correct using get_flow before deleting to avoid mistakes

  • Check if flow is used in production or referenced by other systems before deletion

  • Document why flow was deleted for audit purposes

  • For deleting multiple flows, use delete_flows (batch operation) instead

  • Review flow contents one final time before permanent removal

  • Consider archiving flows to dedicated folder instead of deleting

  • Ensure no running jobs or active sessions using this flow

Common Errors:

  • "Flow not found": flow_id doesn't exist or already deleted (verify with list_flows)

  • "Invalid UUID format": flow_id must be valid UUID string

  • "Cannot delete running flow": Flow has active execution (wait for completion or cancel)

  • "flow_id is required": Must provide flow_id parameter

  • "Unauthorized": API key lacks permission to delete this flow

  • "Flow is referenced": Flow is used as component in other flows (remove references first)

Related Tools:

  • download_flows: Backup flow before deletion for potential recovery

  • list_flows: Find flow_id for flows to delete

  • get_flow: Inspect flow before deletion to confirm it's the right one

  • delete_flows: Delete multiple flows at once (more efficient for bulk operations)

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesThe ID of the flow to delete

TDQS

A4.8/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description is clear about the irreversible, destructive nature of the operation: 'Permanently remove', 'destructive and irreversible', and 'cannot be recovered unless previously backed up'. It also covers common errors like unauthorized access and active flows, which adds transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections including Purpose, Parameters, Returns, Usage Examples, Best Practices, Common Errors, and Related Tools. While lengthy, it is organized and front-loaded with the purpose. Each section adds value, though some repetition could be trimmed.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly states when to use the tool (e.g., cleaning up test/development flows) and provides best practices including when not to use it (e.g., if flow is in production). It also mentions alternatives like 'delete_flows' for bulk operations and 'download_flows' for backup.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

delete_flowsA

Delete multiple flows at once. Pass array of flow IDs.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idsYesArray of flow IDs to delete

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided; description simply states destructive operation without details on rollback, permissions, or side effects. Adequate but minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, front-loaded with key action, no redundant information. Efficient and clear.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple deletion tool with one parameter, the description is nearly complete. Could optionally mention return behavior, but not necessary given tool simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%; the description ('Pass array of flow IDs') adds no new meaning beyond the schema's own description. Baseline score applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Delete multiple flows') and the resource ('flows'), and distinguishes from the sibling tool 'delete_flow' by specifying 'multiple' and 'at once'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies that this tool is for batch deletion, contrasting with the singular delete_flow. No explicit when-not or alternatives mentioned, but the context is clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

memory_base_idYesMemory base ID to delete

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must carry the full burden of behavioral disclosure. It only states 'delete' but omits critical traits such as whether the operation is irreversible, whether cascading deletion occurs (e.g., sessions, messages), permission requirements, or async behavior. This is insufficient for a destructive tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no wasted words. However, its brevity sacrifices important behavioral context, slightly lowering the score from a perfect 5.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite the tool's simplicity (one parameter), the description lacks completeness. It does not mention return value (no output schema), error conditions, or any side effects on associated data (memories, sessions). Given the presence of multiple sibling tools, more context about the deletion's scope would be expected.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Given the simplicity of the tool (one parameter, no output schema), the description is minimally adequate. It does not explain what traces are or the effect of deletion, but the sibling tools and context provide some implicit understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% (flow_id described as 'Flow ID'). The description adds context ('associated with a flow') but does not provide additional semantics beyond the parameter name and schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool deletes all traces for a flow. It uses a specific verb ('Delete') and resource ('all traces'), and the scope ('associated with a flow') distinguishes it from the sibling tool 'delete_trace' which deletes a single trace.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like 'delete_trace' or other related tools. Does not specify prerequisites or conditions for use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

delete_variableA

Delete a variable by ID. Warning: Flows using this variable may be affected.

ParametersJSON Schema
NameRequiredDescriptionDefault
variable_idYesVariable ID (UUID) to delete

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description must inform behavior. The warning about affected flows is helpful, but it omits details like irreversibility, permission requirements, or effects on linked data. Adequate but not comprehensive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences: first states the action, second adds a critical warning. No redundant information; well front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple delete operation with one parameter and no output schema, the description is sufficient. It identifies the action and cautions about side effects. Minor gap: could mention whether deletion is permanent, but not essential.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% (variable_id described), so the description adds no extra meaning beyond what the schema already provides. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Delete a variable by ID.' uses a specific verb (delete) and resource (variable by ID), clearly distinguishing it from sibling tools like create_variable, update_variable, and list_variables.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The warning about flows being affected implies caution, but there is no explicit when-to-use or when-not-to-use guidance, nor any mention of alternatives. Usage context is implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

detect_variablesA

Detect global variables referenced by one or more flow versions.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_version_idsYesFlow version IDs to scan

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, and the description does not disclose read-only nature, permissions required, or any side effects. For a tool with no annotations, the description should add behavioral context beyond the name.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with no unnecessary words. The description is efficiently front-loaded with key information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter, the description is adequate but lacks detail on the output (e.g., what does 'detect' return? variable names/IDs?). Without an output schema, more context on return value would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the parameter is already documented. The description adds no extra meaning, format, or constraints beyond the schema's 'Flow version IDs to scan'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('detect') and the resource ('global variables referenced by flow versions'), distinguishing it from siblings like 'list_variables' which likely returns all variables.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives (e.g., 'list_variables'). The context suggests it is for detecting references, but without exclusions or comparisons, the agent may not differentiate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

download_fileA

Download a specific file from a flow. Returns file content as base64.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID (UUID) containing the file
file_nameYesName of the file to download

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description must convey behavioral traits. It states the core action and return format but omits details like error cases (e.g., file not found), permissions, or size limits, which would be beneficial for an agent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no extraneous words. It is appropriately sized and front-loaded with the key action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity and the absence of an output schema, the description adequately covers the essential behavior and return format. It is complete enough for an agent to understand and use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with each parameter having a clear description. The description adds value by noting the return format (base64), which is not in the schema, but otherwise does not elaborate on parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states 'download a specific file from a flow' and specifies the return format as base64, clearly distinguishing it from sibling tools like upload_file, list_files, or delete_file.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not provide explicit guidance on when to use this tool versus alternatives or any prerequisites. It is adequate for a straightforward download but lacks contextual differentiation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

download_flowsA

Download flows as JSON export. Exports multiple flows for backup or transfer.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idsYesArray of flow IDs (UUIDs) to download

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. It does not disclose if it is read-only, any side effects, authentication needs, rate limits, or error handling. Lacks behavioral context beyond the action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no filler. First sentence states action and format, second adds purpose. Efficient and well-structured for a simple tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with one parameter and no output schema, the description is minimal. It does not explain the output format in detail, limits, or error conditions. Adequate but not complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with parameter description. Tool description adds no extra meaning beyond 'multiple flows' which is already implied by array type. Baseline 3 due to high coverage but no added semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action 'Download flows as JSON export' and the purpose 'for backup or transfer'. It uses specific verb and resource, and distinguishes from siblings like 'get_flow' (single flow) and 'download_project'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for backup or transfer but does not explicitly compare with alternatives like 'get_flow' for single flows or mention when not to use. No when-to-use or when-not-to-use guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

download_folderB

Download entire folder as compressed archive. Returns archive file containing all flows and resources in the folder.

ParametersJSON Schema
NameRequiredDescriptionDefault
folder_idYesFolder ID (UUID) to download

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description bears full responsibility. It only states it returns an archive file but fails to disclose file format, size limits, sync/async behavior, or any side effects (none expected but not confirmed).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no unnecessary words. Front-loaded with main action and output.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a simple single-parameter tool. However, missing details like expected file extension, whether it's a direct download link or binary, and if there are any rate limits or timeouts.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with clear description of 'folder_id' parameter. The tool description adds no extra meaning beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the verb 'download', the resource 'entire folder', and the output 'compressed archive'. Distinguishes from siblings like 'download_file' and 'download_flows'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Does not provide any guidance on when to use this tool versus alternatives, nor any prerequisites (e.g., folder must exist, permissions needed). No mention of when not to use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

download_projectA

Download a project as JSON export. Exports project for backup or transfer.

ParametersJSON Schema
NameRequiredDescriptionDefault
project_idYesProject ID (UUID) to download

TDQS

A3.7/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description should disclose behavioral traits. It only states the action and purpose, but does not explain how the download is delivered (e.g., file vs response body), error scenarios, or side effects. The agent lacks important behavioral details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description consists of two short, clear sentences with no redundant information. It is front-loaded and efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter and no output schema, the description covers the basic purpose and output format. However, it lacks details on the exact response behavior (e.g., file download vs JSON in body) and error handling, which are important for an agent to invoke correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% for the single parameter project_id, with a description in the schema. The tool description does not add any further meaning beyond the schema, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Download', the resource 'a project', and the format 'as JSON export'. It distinguishes from sibling tools like get_project which likely returns project data but not as a downloadable export, and upload_project which does the opposite.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions usage for 'backup or transfer', providing clear context. However, it does not explicitly state when not to use it or compare to alternatives like get_project, which might be more appropriate for viewing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

expand_flowsB

Expand flows by resolving component references into full flow definitions. Pass the expansion request payload as the body object.

ParametersJSON Schema
NameRequiredDescriptionDefault
bodyYesFlow expansion request payload

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description must disclose behavioral traits. It only says 'resolve component references', but does not mention if the operation is destructive, requires permissions, has side effects, or any rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, efficient and to the point. No unnecessary words, though it could be expanded with more detail without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has one complex object parameter, no output schema, and no annotations. The description does not explain the structure of the request body or what the response contains, leaving significant gaps for an AI agent to understand the full context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%; the description of the 'body' parameter as 'Flow expansion request payload' adds no additional meaning beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the action (expand flows) and the specific operation (resolving component references into full flow definitions). This distinguishes it from sibling tools like get_flow, run_flow, etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides basic instruction to pass the expansion request payload as the body object, but lacks explicit context on when to use this tool vs alternatives (e.g., get_flow) or any exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

flush_memory_baseB

Flush a memory base session, persisting captured memories.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesSession ID to flush
memory_base_idYesMemory base ID

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It states 'persisting captured memories' but does not explain whether the session is preserved, cleared, or deleted after flushing, nor does it mention required permissions or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no redundant words. It is front-loaded with the action and includes the key effect.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with two string parameters, the description is adequate but lacks any mention of return values, error scenarios, or behavior after execution. Given no output schema, some additional context would be helpful.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for both parameters. The description adds no extra meaning beyond the schema, meeting the baseline of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'flush' and the resource 'memory base session', and specifies the effect 'persisting captured memories'. It distinguishes this tool from siblings like delete_memory_base or update_memory_base by using the specific action 'flush'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, conditions, or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_a2a_agent_cardA

Get the A2A agent card (.well-known/agent-card.json) for a flow (Langflow 1.11.0). Requires server-side A2A enablement.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full behavioral disclosure burden. It states the tool gets a resource (read operation) and notes a requirement, but does not disclose side effects, error conditions (e.g., invalid flow_id, disabled A2A), permissions beyond enablement, or response format. Adequate for a simple read tool but could be more transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is exceptionally concise: two sentences, no filler. The first sentence states the purpose directly, and the second adds a critical prerequisite. Every word serves a purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one required parameter, no output schema, no annotations), the description is largely complete. It covers purpose, version, and a prerequisite. It could hint at error handling (e.g., what happens if not enabled) or the return format (JSON), but overall it provides sufficient context for an agent to decide and use the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage with 'flow_id' described as 'Flow ID'. The description adds context by linking the flow to Langflow 1.11.0 and specifying the card's endpoint path, which goes beyond the schema's minimal description. This aids the agent in understanding the parameter's role.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it retrieves the A2A agent card (.well-known/agent-card.json) for a specific flow, with the verb 'Get' and resource identification. It also specifies the Langflow version, aiding context. However, it does not explicitly differentiate from sibling tools like list_a2a_agents or invoke_a2a_jsonrpc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides a prerequisite ('Requires server-side A2A enablement'), which implies when the tool can be used. However, it lacks explicit guidance on when to use this tool versus alternatives, such as when to get a list of agents or invoke JSON-RPC instead. No when-not-to-use or alternative names are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_agentic_fileC

Get an agentic workspace file, optionally as a downloadable payload.

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesFile path
downloadNoReturn the file content for download

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must carry the full burden. It only states the tool can optionally return a downloadable payload but does not disclose what the response format is (e.g., raw content, URL, binary), error behavior, or any side effects. For a retrieval tool, this is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that conveys the core purpose efficiently. It is concise with no wasted words, though it could benefit from additional detail without losing brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has no output schema and two parameters, the description should explain the return value (what constitutes a 'downloadable payload'?) and the scope ('agentic workspace file' is not defined). It lacks completeness for a tool that likely returns file data.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with both parameters described adequately. The description adds minimal value beyond the schema—it hints at the download parameter's purpose but doesn't clarify the download payload format or behavior. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves an agentic workspace file with an optional download feature. It specifies the resource type (agentic workspace file) which helps distinguish it from general file tools, though it doesn't explicitly differentiate from siblings like `download_file` or `get_file_v2`.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It lacks prerequisites, exclusions, or context about when the download option is appropriate. The agent must infer usage entirely from the name and basic description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavioral traits. It implies read-only access but does not mention permissions, performance impact, or what happens when filters match no results. The description is too terse for a 9-parameter query tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no wasted words. The information is front-loaded and directly states the core function.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite 9 parameters and no output schema or annotations, the description provides almost no context about the return format, audit log semantics, or usage patterns. It is insufficient for an agent to use the tool effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All 9 parameters are described in the schema with 100% coverage. The description adds no new meaning beyond summarizing 'with filters and pagination'. Baseline of 3 is appropriate as it does not enhance understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool queries the authorization audit log with filters and pagination, using a specific verb and resource. However, it does not differentiate from sibling tools like get_logs or list_traces, which might cause confusion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. The description does not mention prerequisites, use cases, or which scenarios are appropriate, leaving the agent to infer usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Without annotations, the description carries full burden but only states the action. No mention of permissions required, error behavior, or what happens if role_id does not exist.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence with no unnecessary words. It is front-loaded and concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given low complexity (one parameter, no nested objects, no output schema), the description is adequate. It could mention that it returns a role object, but not required.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% for the single required parameter 'role_id', with its description 'Role ID'. The tool description does not add any additional meaning beyond the schema.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden for behavioral disclosure. It only states 'Get', failing to mention that this is a read-only operation, any required permissions, potential side effects, or response details. This is insufficient for an agent to understand the tool's impact.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no wasted words. It is appropriately concise for the tool's simplicity, though it could include more detail without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple getter with one parameter and no output schema, the description provides minimal but sufficient context. However, it could be improved by explaining what a 'resource share' is and what fields appear in the response.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents the share_id parameter. The description adds no additional meaning beyond what the schema provides, so baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get') and the resource ('a single resource share') with the identifier ('by ID'), distinguishing it from sibling tools like list_authz_shares, create_authz_share, etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use for retrieving a specific share, but does not provide explicit guidance on when to use it versus alternatives like list_authz_shares for multiple shares. No exclusions or prerequisites are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_authz_teamA

Get a single authorization team by ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
team_idYesTeam ID

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the fundamental action without mentioning side effects, return structure, error behavior, or permission requirements. The agent is left to assume it's a read operation with no additional context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description consists of a single sentence with 6 words, instantly conveying the tool's purpose. It is front-loaded and contains no extraneous information, making it highly efficient for an agent to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (get by ID) and the description is adequate for basic understanding. However, it lacks details about the response content (e.g., whether it returns full team details or just an ID), and there is no output schema to fill the gap. For a tool in a complex domain with many siblings, slightly more context would be beneficial.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with a single required parameter 'team_id' described as 'Team ID'. The tool description adds no further meaning beyond the schema. Given the parameter is straightforward, the minimal addition is acceptable but does not improve clarity or usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Get a single authorization team by ID.' uses a specific verb ('Get') and resource ('authorization team') with a clear method ('by ID'). It immediately distinguishes from sibling tools like list_authz_teams (which retrieves multiple teams) or create/update/delete operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when a specific team ID is known, but provides no explicit guidance on when to use this tool versus alternatives. It doesn't mention that list_authz_teams should be used for retrieving multiple teams or for discovery. The usage context is inferred but not stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_basic_examplesA

Get basic example flows. Returns a list of pre-built example flows for learning and templates.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.8/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description should disclose behavioral traits. It only states that it returns a list of pre-built example flows. No information about authentication, mutability, side effects, or response format. Minimal transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is a single, front-loaded sentence. It is appropriately concise with no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (no parameters, no output schema), the description is adequate. However, it could mention the structure or purpose of the returned list more explicitly, but overall it is sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has zero parameters, and schema coverage is 100%. Description adds no parameter info as none are needed. Baseline score of 4 applies as per rubric.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the tool retrieves basic example flows for learning and templates, using specific verb 'Get' and resource 'basic example flows'. It is easily distinguishable from siblings like 'get_flow' and 'list_flows'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Description implies usage for learning and templates but does not provide explicit guidance on when to use this tool versus alternatives or when not to use it. No exclusionary or comparative language.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_build_statusA

Get build status and events for a specific build job. Use polling mode to check async build progress.

ParametersJSON Schema
NameRequiredDescriptionDefault
job_idYesBuild job ID returned from build_flow
event_deliveryNoEvent delivery mode: "polling", "streaming", or "direct" (default: "polling")

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears the full burden of behavioral disclosure. It states the tool retrieves data (status and events), implying a read-only operation, but does not clarify side effects, authorization requirements, rate limits, or response behavior. For a tool with no annotations, this is insufficient for transparency beyond the obvious.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: two sentences with no redundancy. The first sentence states the core purpose, the second provides a practical usage hint. Every word contributes meaning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (2 params, no output schema), the description is adequate but not complete. It explains the purpose and hints at usage mode, but does not describe the structure of returned status/events or explain the alternatives (streaming, direct). For agents to use it effectively, more context about the response format would be beneficial.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already describes both parameters with 100% coverage (job_id and event_delivery). The description adds context by advising to use polling mode, which reinforces the default value. This adds modest value but does not significantly enhance understanding beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states that the tool retrieves build status and events for a specific build job. The verb 'Get' and the resource 'build status and events' are specific. The parameter 'job_id' implies it targets a single job, distinguishing it from list-oriented siblings like 'get_monitor_builds'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides a usage hint: 'Use polling mode to check async build progress.' This advises on the preferred event delivery mode. However, it does not explicitly mention when to avoid this tool or compare it to alternatives like 'streaming' or 'direct' modes, neither does it address scenarios where polling is inappropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_current_userA

Get information about the currently authenticated user. Returns user profile including id, username, email, is_active, is_superuser status, and profile image.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It correctly indicates a read-only operation and lists returned fields. However, it does not mention authentication requirements (assumed) or potential errors like unauthenticated calls.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no unnecessary words. It efficiently conveys the tool's action and output.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description lists several important return fields (id, username, email, etc.), which is fairly complete for a simple tool. Minor omission: could mention if additional fields exist, but overall sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters and schema coverage is 100%. The description adds value by explaining the tool's purpose and return fields, meeting the baseline of 4 for parameterless tools.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Get information about the currently authenticated user' using a specific verb and resource. It lists key return fields (id, username, email, is_active, etc.) and implicitly distinguishes from sibling tools like get_user or list_users by focusing on the authenticated user.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for fetching the current user's profile but does not explicitly contrast with alternatives like get_user (for a specific user) or list_users (for all users). No when-not-to-use guidance is provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_default_modelC

ParametersJSON Schema
NameRequiredDescriptionDefault
model_typeYesModel type

TDQS

C2.8/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description must fully disclose behavioral traits. It only states the action, omitting whether it is read-only, what the return value looks like, possible side effects, or required permissions. The agent is left guessing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short (8 words), which is concise but lacks sufficient detail to be useful. It sacrifices informativeness for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity (1 parameter, no output schema), the description should at least hint at the return format or behavior. It does not explain what 'default model' means, leaving a significant gap for the agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% (the sole parameter 'model_type' is described in the schema as 'Model type'). The description adds no additional meaning beyond the schema, which already sufficiently documents the parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and the resource 'default model' with a qualifying condition 'for a given model type'. It is specific and unambiguous, though it does not differentiate from sibling tools like 'list_models' or 'set_default_model'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives (e.g., when to call 'get_default_model' vs 'list_models'). There is no mention of prerequisites, context, or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_embedding_model_optionsA

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Without annotations, the description carries full burden. It truthfully states a simple read operation but does not disclose potential rate limits, authentication requirements, or whether the result is a list. Minimal disclosure is adequate for a straightforward retrieval tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no redundancy. Every word contributes to the purpose. Ideal conciseness for a simple tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no parameters and no output schema, the description is complete enough to indicate basic functionality. However, it could provide context about how the returned options are used (e.g., for setting default embedding model) to improve integration with sibling tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has zero parameters, so the baseline is 4 per guidelines. The description adds no extra meaning beyond the schema, but none is needed as there are no parameters to describe.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states 'Get available embedding model options,' which uses a specific verb and resource. It clearly differentiates from siblings like get_language_model_options and get_default_model by focusing on embedding models.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus siblings such as get_default_model or get_language_model_options. The description lacks context about its role in the model selection workflow.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_extension_eventsC

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It only states the basic action and parameter, omitting any behavior such as pagination limits, rate limiting, or what happens when no events exist. The minimal disclosure is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise—one sentence with no fluff. However, it sacrifices necessary detail for brevity. Every sentence earns its place, but additional context would improve utility.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description should explain what the response contains (e.g., array of events, fields). It does not, leaving agents to guess the return structure. Combined with missing annotations, the description is incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already explains the 'since' parameter fully. The description echoes this without adding new meaning (e.g., format constraints, default behavior). Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves extension events for the current user, with an optional cursor parameter. It uses a specific verb and resource, standing out from many sibling tools that deal with flows, models, or other entities.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the core purpose, and every word is non-redundant. It is appropriately sized for a simple retrieval tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with only 2 parameters and no output schema, the description covers the essential operation. However, it could mention the user-scoped nature explicitly and note that file_id is required (though schema already indicates this).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the description essentially restates the schema descriptions ('File ID', 'Return file content in the response'). It adds no additional meaning beyond what is already in the input schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get', the resource 'a user-scoped file by ID', and includes the API endpoint. It distinguishes this tool from sibling file tools (e.g., list_files_v2, upload_file_v2) by specifying single file retrieval.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for retrieving a file by ID and optionally its content, but it does not explicitly state when not to use this tool or mention any alternatives (e.g., download_file for raw bytes, get_file_image for thumbnails).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_flowA

Retrieve complete details and configuration of a specific flow.

Purpose: Fetch comprehensive information about a flow including its full node graph, component configurations, connections, and metadata. Essential for inspecting flow structure, debugging workflows, and preparing flows for modification or execution.

Parameters:

  • flow_id (required, UUID string): The unique identifier of the flow to retrieve (obtained from list_flows or create_flow)

Returns: FlowRead object containing:

  • id (UUID): Flow's unique identifier

  • name (string): Flow display name

  • description (string): Flow purpose description

  • folder_id (UUID): Parent folder identifier if organized

  • user_id (UUID): Owner user identifier

  • created_at, updated_at (ISO timestamps): Flow lifecycle timestamps

  • data (object): Complete flow structure including:

    • nodes (array): All component nodes with their configurations

    • edges (array): Connections between nodes

    • viewport (object): Canvas positioning data

    • description (string): Flow-level documentation

Usage Examples:

  1. Get flow details: { flow_id: "550e8400-e29b-41d4-a716-446655440000" }

  2. Inspect before modification: { flow_id: "flow-uuid-from-list" }

  3. Debug flow structure: { flow_id: "failing-flow-uuid" }

Best Practices:

  • Use list_flows first to discover available flow_id values

  • Cache flow data locally to reduce API calls when repeatedly accessing same flow

  • Check updated_at timestamp to detect if flow changed since last retrieval

  • Inspect data.nodes to understand flow's component structure

  • Review data.edges to trace data flow between components

  • Validate flow_id format (must be valid UUID) before making request

Common Errors:

  • "Flow not found": flow_id doesn't exist or was deleted (verify with list_flows)

  • "Invalid UUID format": flow_id must be valid UUID string (e.g., "550e8400-e29b-41d4-a716-446655440000")

  • "Unauthorized": API key lacks permission to access this flow

  • "Flow ID is required": Must provide flow_id parameter

  • Connection timeout: Check Langflow instance availability and network connectivity

Related Tools:

  • list_flows: Find available flow_id values

  • update_flow: Modify flow configuration after retrieval

  • run_flow: Execute flow after inspecting its structure

  • build_flow: Compile and validate flow structure

  • delete_flow: Remove flow after inspection confirms it's no longer needed

flow_idYesThe ID of the flow to retrieve

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It details the return structure (FlowRead object with nodes, edges, viewport) and common errors, implying it's a read-only operation. It does not contradict any annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear headings but is quite long for a simple retrieval tool. It could be more concise while retaining key information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite no output schema, the description thoroughly explains the return object structure, common errors, and provides examples. It covers all necessary context for an agent to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% (one parameter flow_id with type string). The description adds that flow_id is a UUID, where to obtain it (list_flows, create_flow), and includes usage examples and validation advice, adding value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves complete details and configuration of a specific flow, using specific verbs like 'Retrieve' and 'Fetch'. It distinguishes between retrieving, modifying, and executing flows in the 'Related Tools' section.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use this tool (inspect flow structure, debug, prepare for modification). It includes best practices (list_flows first, cache data, check timestamps) and explicitly lists alternative tools with explanations.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

sinceNoOptional cursor: only events since this value
flow_idYesFlow ID (UUID)

TDQS

A3.6/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must fully disclose behavioral traits. It mentions optional filtering but omits details like pagination, whether events are returned exhaustively, rate limits, or any idempotency/read-only characteristics. This is insufficient for a complete understanding.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description consists of two concise sentences, front-loading the purpose. Every word is necessary; no filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (2 parameters, no output schema) and the complete schema descriptions, the description is largely sufficient. It could briefly note that results are a stream or that it's read-only, but it covers the essential purpose and filter option. No major gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%: both parameters have descriptions in the schema. The description restates that 'since' is an optional cursor/timestamp but adds no meaningful context beyond what the schema already provides. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly uses 'Get' verb and identifies the resource as 'event stream/history for a flow'. It distinguishes from sibling tools like 'get_flow' (general info) and 'create_flow_event' (creation), making its purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Description states optional filter by cursor/timestamp but provides no explicit guidance on when to use this tool vs alternatives like 'get_workflow_events' or how it differs from 'get_flow'. Usage context is implied but exclusions are absent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_flow_note_translationsB

Get localized note translations for a flow by ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID

TDQS

B3.1/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, and the description does not disclose any behavioral traits (e.g., read-only, performance, side effects). It simply repeats the operation without additional context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that gets straight to the point with no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple lookup tool, the description adequately explains the input, but it does not mention the return value or format, which is a gap given no output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds minimal meaning over the schema: it mentions 'by ID' which aligns with the flow_id parameter. Schema coverage is 100%, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific verb 'Get' and resource 'localized note translations for a flow by ID', distinguishing it from sibling tools like get_flow or get_flow_version.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives, nor any prerequisites or exclusions. The description only states what it does.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_flow_versionC

Get a specific saved version of a flow by version ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID (UUID)
version_idYesVersion ID

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Without annotations, the description must disclose behavioral traits. It implies a read-only operation ('Get') but does not mention permissions, side effects, or what happens if the version does not exist. The description provides minimal behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, 12 words, front-loaded with the core purpose. Every word is necessary, and there is no superfluous information. It is as concise as possible.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (get by two IDs) and no output schema exists. The description fails to indicate what is returned (e.g., the version object details). It also does not clarify the relationship between flow and version. Context is incomplete for even a basic retrieval operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters are fully described in the input structure. The description adds no extra meaning beyond the schema (e.g., clarifying formats or constraints). Baseline score of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'get', the resource 'specific saved version of a flow', and the key parameter 'version ID'. It distinguishes from siblings like 'list_flow_versions' by specifying a single version retrieval. However, it could be more explicit about what constitutes a 'version' in this context.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives such as 'get_version' or 'list_flow_versions'. No mention of prerequisites, exclusions, or context. The description is purely functional without any usage hints.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_folderB

Get details of a specific folder by ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
folder_idYesFolder ID (UUID)

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It only states it 'gets details' but does not disclose side effects (presumably none), permissions, error handling, or what 'details' encompasses. Minimal transparency for a read operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no redundant words. Directly communicates the core purpose with minimal text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple get-by-ID tool with no output schema and only one parameter, the description is mostly sufficient. It could mention expectations (e.g., folder must exist) but the current text is adequate for a basic retrieval operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema documentation covers the single parameter (folder_id as UUID) at 100%. The description's phrase 'by ID' only repeats the schema. No additional semantic value added beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (Get), resource (folder details), and the required input (ID). Among siblings like list_folders, update_folder, delete_folder, this tool is unambiguously for retrieving a single folder's details.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., list_folders for all folders), no prerequisites or context provided. The agent is left to infer usage from the name and siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_health_checkA

Get the detailed health check report from the Langflow server root /health_check endpoint.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.6/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Does not disclose whether the operation is read-only, requires authentication, or has side effects. The name implies read-only but is not explicit.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with key information (verb, resource, endpoint). No unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a no-parameter, no-output-schema tool, the description is mostly adequate. It defines the action and source. However, it does not describe the return format or content of the report, which would be helpful without an output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist, so baseline is 4. Description adds value by specifying the endpoint URL, but could mention that no input is needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the verb 'Get' and the resource 'detailed health check report', with specific endpoint '/health_check', distinguishing it from other tools like 'health_check' by specifying it returns a report.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives. Does not mention prerequisites, exclusions, or context where it is appropriate, despite many sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_job_queue_metricsA

Get job queue metrics (superuser-only).

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the behavioral constraint that only superusers can use this tool, which is crucial. With no annotations, the description carries full burden, but it does not mention side effects, whether the operation is read-only (though implied by 'get'), or what response to expect (no output schema provided). This leaves some transparency gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise, using a single sentence. It front-loads the action and resource, and adds the superuser constraint efficiently. However, it could be slightly more detailed without being verbose, so a 4 rather than 5.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that there is no output schema, the description should explain what the tool returns (e.g., the structure of metrics). It fails to do so, leaving a gap in completeness. The superuser note is helpful but insufficient to fully inform an agent about the tool's output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are no parameters, so the schema coverage is trivially 100%. The description adds meaning beyond the empty schema by naming the resource and the access restriction. According to the guidelines, 0 parameters yields a baseline of 4, and the description adds relevant context, so this score is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get') and the resource ('job queue metrics'), fulfilling the specific verb+resource requirement. It also specifies a scope constraint ('superuser-only'), which helps distinguish it from other 'get_' tools among the many siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes the important context that this tool is 'superuser-only', implying restricted access. However, it does not provide explicit guidance on when to use this tool versus alternatives, nor does it state when not to use it or mention any prerequisites beyond superuser status.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_knowledge_baseA

Get detailed information about a specific knowledge base by name.

ParametersJSON Schema
NameRequiredDescriptionDefault
kb_nameYesKnowledge base name/ID

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Only says 'Get detailed information', omitting whether it requires authentication, is read-only, error handling (e.g., nonexistent kb_name), or response format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single 12-word sentence, no unnecessary words. Front-loaded and efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a simple single-parameter tool, but lacks details on return values (no output schema) and behavioral context. Could benefit from mentioning what 'detailed information' entails.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% (kb_name described). Description adds only 'by name', which reinforces but doesn't meaningfully supplement schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states verb 'Get', resource 'knowledge base', and scope 'by name'. It distinguishes from sibling tools like list_knowledge_bases (list all) or create_knowledge_base (create new).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied (call with kb_name to get details), but no explicit when-to-use or when-not-to-use guidance. No mention of alternatives among siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_knowledge_base_metadata_keysB

Get the available metadata keys for a knowledge base.

ParametersJSON Schema
NameRequiredDescriptionDefault
kb_nameYesKnowledge base name

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, but the description does not disclose any behavioral traits beyond the basic operation. It omits details like authentication requirements or whether the call is read-only, though the name implies a read.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no filler, efficiently conveying the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity (one parameter, no output schema), the description suffices for basic understanding, though it could add detail on the returned keys.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single parameter 'kb_name'. The tool description adds general context ('for a knowledge base') but not additional meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get') and the resource ('available metadata keys for a knowledge base'), distinguishing it from sibling tools like get_knowledge_base which retrieves the full object.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., when to retrieve just metadata keys vs. the full knowledge base). No exclusions or context provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_knowledge_base_runC

Get a single knowledge base ingestion run by ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
run_idYesIngestion run ID
kb_nameYesKnowledge base name

TDQS

C2.8/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must convey behavioral traits. It only states the basic action without mentioning read-only nature, required permissions, side effects, or what the response contains. The agent has insufficient information to assess safety or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very concise (one sentence) but lacks important details, making it borderline under-specified. It is not verbose, but the brevity sacrifices completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of output schema and annotations, the description is insufficient. It does not explain what data is returned, any prerequisites, or how the tool fits into workflows. The agent would need to guess the return structure.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the parameters are adequately described in the schema. The description adds no extra meaning beyond what is already in the schema, such as how to obtain run_id or the relationship between kb_name and the run.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get') and the resource ('a single knowledge base ingestion run by ID'). It is specific and distinguishes from the sibling 'list_knowledge_base_runs' through the word 'single', but does not explicitly differentiate in the description.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., list_knowledge_base_runs). It does not mention prerequisites or context for use, leaving the agent to infer from the name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.5/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavior. It implies a read-only operation but does not explain permissions, side effects, or output characteristics. Adequate but minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence with no wasted words. It is concise, but could be slightly more informative without harming brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Without an output schema, the description should clarify the return value (e.g., a list of model names/IDs). It does not, leaving agents to infer the response structure, which is insufficient for a tool with no parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters and schema coverage is 100%, so the description does not need to add parameter details. The baseline for no parameters is 4, and the description adds no extra meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'get' and the resource 'available language (LLM) model options,' distinguishing it from siblings like get_default_model (which gets a single default) and get_embedding_model_options (which gets a different type).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool over alternatives such as get_default_model or get_embedding_model_options. The description does not specify any context or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_logsA

ParametersJSON Schema
NameRequiredDescriptionDefault
streamNoEnable streaming mode for real-time logs (default: false)

TDQS

A3.7/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It only mentions streaming capability but omits important behavioral details such as authentication, rate limits, pagination, or the format of returned data. This is insufficient for a data retrieval tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, concise and to the point. Every sentence adds value, with no redundant information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one optional parameter and no output schema, the description is moderately complete. It could be improved by clarifying the scope of 'system logs' and any implicit filters, but it is adequate for basic usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with the stream parameter already described. The description restates its purpose without adding new meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Get the MCP Composer URL for a project.

ParametersJSON Schema
NameRequiredDescriptionDefault
project_idYesProject ID (UUID)

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description must carry full disclosure burden. It only states 'Get' implying a read operation, but does not clarify if it requires authentication, is idempotent, or what constraints exist (e.g., project must have composer feature enabled). Lacks side-effect or error detail.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with no fluff. It would benefit from slightly more context (e.g., purpose of the URL) but remains efficient and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the agent lacks information on what the response contains (e.g., a full URL, a path). With many similar siblings, the description is too minimal to fully equip the agent for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 100% description coverage for the single parameter (project_id as UUID). Description adds no extra meaning beyond the schema, earning the baseline score.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states it retrieves the MCP Composer URL for a project using 'Get' verb and specific resource. Distinguishes from sibling tools like get_mcp_server or get_mcp_project_config by naming the exact URL target, though does not explicitly contrast.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus related MCP tools (e.g., get_mcp_project_config). No mention of prerequisites or context, leaving the agent to infer usage entirely from the name.

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden for behavioral disclosure. It only states a read operation with an optional filter, but omits any side effects, permission requirements, rate limits, or response structure. Minimal transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no extraneous information. Front-loaded with the core action and optional filter. Efficient and well-structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and no annotations, the description is minimal. It does not explain what 'MCP configuration' includes or what the return value looks like. However, the tool is simple (read with optional filter) and part of a family, so completeness is adequate but not thorough.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description mentions the optional filter 'only MCP-enabled flows', but this directly mirrors the schema's parameter description. It adds no new meaning beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and the resource 'MCP configuration for a project', with an optional filter. It distinguishes from siblings like update_mcp_project_config (a write operation) and list_mcp_servers (which lists servers, not project config).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use this tool vs. alternatives such as get_mcp_project_installed or get_mcp_project_composer_url. The description is purely functional and does not provide context for selection.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavioral traits. It does not state whether the operation is read-only, requires permissions, or has any side effects. The tool name implies a read, but the description lacks explicit confirmation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no filler words. Every word is necessary and front-loaded with the action and resource.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple retrieval tool with one parameter, the description is functional but lacks detail about the return value (e.g., format, possible values). Without an output schema, the agent is left guessing the response structure.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds no extra meaning beyond the 'project_id' parameter's schema description. It does not explain how to obtain the ID or any constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves 'installation status of a project as an MCP server across clients,' defining a specific verb (Get) and resource (installation status). It distinguishes from siblings like 'get_mcp_server' and 'install_mcp_project' by focusing on status across clients.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool vs. alternatives, nor does it mention prerequisites or when not to use it. Agents must infer usage from the tool name and sibling context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_mcp_serverB

Get the configuration of a specific MCP server by name.

ParametersJSON Schema
NameRequiredDescriptionDefault
server_nameYesMCP server name

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states 'Get the configuration' (a read operation) but does not mention authorization requirements, error handling (e.g., what if the server does not exist), performance characteristics, or any side effects. This is insufficient for a tool with no annotation support.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is short and front-loaded with the key action and resource. Every word serves a purpose; there is no redundancy or unnecessary elaboration. This is an exemplary concise description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given there is no output schema, the description should hint at what constitutes the 'configuration' (e.g., fields returned). It only says 'configuration' without elaboration. Additionally, error cases or prerequisites are not mentioned. While the tool is simple, the description could provide a bit more context, such as typical usage context, but it is not severely lacking.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% with the parameter 'server_name' described as 'MCP server name'. The description adds 'by name' reinforcing the parameter's role. However, since the schema already conveys the same information clearly, the description adds minimal additional meaning beyond confirming the parameter's purpose. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and the resource 'configuration of a specific MCP server', using the parameter 'by name' to identify the server. This distinguishes it from sibling tools like list_mcp_servers (list all) and create_mcp_server (create new), making the purpose highly clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not provide any guidance on when to use this tool versus alternatives. It lacks explicit 'when to use' or 'when not to use' instructions, nor does it reference sibling tools. Without such context, an agent may struggle to choose the correct tool among similar options.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_memory_baseA

Get a single memory base by ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
memory_base_idYesMemory base ID

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavioral traits. It only states the action, omitting details about permissions, idempotency, error handling, or that it is a read-only operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that front-loads the action and resource. No extraneous words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple retrieval tool with one parameter and no output schema, the description is adequate but could mention the return value or prerequisites for completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single parameter, and the description adds no extra meaning beyond 'by ID' which is also explicit in the schema. The description provides marginal value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb (Get), resource (memory base), and method (by ID), distinguishing it from sibling tools like list_memory_bases which retrieve multiple memory bases.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when you have a specific memory base ID, but it lacks explicit guidance on when to use this tool versus alternatives or any caveats.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden. It indicates it is a read operation and mentions the returned data, but lacks details on permissions, rate limits, or side effects. It adds moderate behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, each adding value: purpose, retrieved data, use cases. No fluff, and essential information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter read tool with no output schema, the description covers purpose, use cases, and what is returned. It is mostly complete, though it could mention if the history is limited or paginated.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter (flow_id) is fully described in the schema. The description adds little beyond restating 'specific flow,' so the schema already covers semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and the resource 'build execution history for a specific flow,' distinguishing it from sibling tools like get_build_status or delete_monitor_builds. It also mentions the specific data model retrieved.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context by stating it is essential for monitoring, debugging, and tracking, but does not explicitly mention when not to use or direct alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_monitor_messageA

Get detailed information about a specific message by ID. Retrieves complete message data including sender, content, timestamp, and metadata. Useful for inspecting individual message details and debugging message-related issues.

ParametersJSON Schema

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses that it retrieves 'complete message data including sender, content, timestamp, and metadata', making it clear it's a read operation. No annotations are provided, so the description carries the burden; it adequately conveys behavior without side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences: first states purpose, second adds a use case. No redundant words, front-loaded with key information, efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter and no output schema, the description covers what it does, what data it returns, and when to use it. Minor omission: no mention of error behavior if message not found, but that's acceptable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter message_id is described in the schema with 'Message ID (UUID) to retrieve'. The description adds no additional semantics beyond the schema, and schema coverage is 100%, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Get detailed information about a specific message by ID', using a specific verb and resource. It differentiates from siblings like get_monitor_messages (list) and update_monitor_message by focusing on a single message retrieval.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description says it is 'useful for inspecting individual message details and debugging message-related issues', providing clear context. However, it does not explicitly mention when not to use it or suggest alternatives like get_monitor_messages for listing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_monitor_messagesB

Query chat/message history with flexible filtering options. Retrieve messages filtered by flow ID, session, sender, or sender name. Supports custom ordering for chronological or reverse-chronological message retrieval. Essential for debugging chat flows, analyzing conversation patterns, and monitoring user interactions.

sender_nameNoOptional sender name to filter messages

TDQS

B3.2/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavior. It mentions filtering and custom ordering, but does not specify if the operation is read-only, rate limits, authentication needs, or what happens with no filters (e.g., returns all). Partial but not comprehensive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with core action and purpose. Each sentence adds value. No unnecessary repetition, but could be slightly more streamlined.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description explains filtering and ordering, but lacks information on return structure, pagination, or limits. For a query tool without output schema, this is a gap. It is adequate but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with individual parameter descriptions. The description adds context about flexible filtering and custom ordering, but does not specify valid values for order_by. Since the schema already carries the burden, the description adds minimal extra value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it queries chat/message history with filtering. It distinguishes from siblings by emphasizing flexible filtering and custom ordering, but does not explicitly compare to similar monitor tools like get_monitor_sessions.

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so the description alone must convey behavior. It states it's a 'get' operation (read-only), which is correct, but does not disclose any additional traits (e.g., no side effects, no auth requirements). For a zero-parameter read tool, this is acceptable but not proactive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, no wasted words, front-loaded with key information. Perfectly concise and well-structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no parameters and no output schema, the description tells the agent what the tool does. It could implicitly suggest that no input is needed, but omitting explicit 'no input required' is a minor gap. Still, it's largely complete for a simple retrieval tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters and schema coverage is 100%, so baseline is 3. The description does not add parameter information because none exists.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Get') and clearly identifies the resource ('mapping between model providers and their required global variables'). This is distinct from sibling tools like get_default_model or get_language_model_options, so purpose is clear and differentiated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit when-to-use or alternatives are provided. The usage is implied: use when you need the mapping. For a simple retrieval tool with no parameters, this is minimally adequate but lacks guidance for complex scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_public_flowA

Get a public flow by ID without authentication. Public flows can be accessed by anyone without API key or login credentials.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID (UUID) of the public flow

It notes that streaming is not incrementally surfaced and the initial payload is returned, which is important behavioral context. However, it does not mention side effects, required permissions, or what happens on invalid job IDs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences—concise and front-loaded. The first sentence states the core purpose and version, the second adds a critical behavioral caveat. No redundant or extraneous content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description explains the tool's behavior (initial payload, non-incremental streaming) but does not describe the return format or possible error conditions. Without an output schema, this information would help completeness. Overall adequate for the tool's simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 100% (the only parameter 'job_id' is described as 'Workflow job ID'). The description does not add additional meaning beyond the schema, so per the baseline rule for high coverage, a score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 're-attach', the resource 'workflow job event stream', and specifies the key parameter 'job ID' (Langflow 1.11.0). It distinguishes this tool from siblings by focusing on event stream re-attachment.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for re-attaching to an existing event stream, but does not explicitly state when to use this tool vs alternatives like 'get_workflow_result' or 'run_workflow'. No exclusions or alternative suggestions are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_workflow_resultC

job_idNoOptional workflow job ID

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It does not state whether the tool is read-only, requires any authorization, or what happens if job_id is omitted (e.g., returns default or latest). The description lacks critical behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no wasted words. However, it could benefit from slightly more detail without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has no output schema, so the description should explain the return value. It does not mention what is returned (e.g., the status, data, or format). Given the low complexity, the description is incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the description merely echoes the schema by noting the optional job ID. No additional meaning or constraints are added. Baseline 3 is appropriate as the schema already provides adequate param documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the tool retrieves the result of a workflow run, optionally filtered by job ID. The verb 'Get' and resource 'result of a workflow run' are specific, but it does not differentiate from siblings like 'get_workflow_events', which is a related retrieval tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. It is implied for retrieving results after a workflow run, but there is no mention of prerequisites, exclusions, or when to use other tools like 'get_workflow_events' or 'get_task_status'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

health_checkA

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Description discloses return values (health status and system information) and purpose (verify operational status). No annotations, but description carries full burden and does so adequately.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no wasted words, purpose front-loaded. Perfectly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given zero parameters, no output schema, and simple nature, description covers everything needed: what it does, what it returns, and when to use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters in schema; description does not need to add parameter info. Baseline 4 for 0 parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states verb 'Check' and resource 'Langflow instance health status'. It distinguishes from siblings by focusing on health verification, which is unique among many tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says 'Use to verify the API is accessible and operational', providing clear context. No exclusions or alternatives needed for a health check.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

ingest_knowledge_baseC

Ingest a file into an existing knowledge base. Provide base64 file content, filename, and optional ingestion params.

ParametersJSON Schema
NameRequiredDescriptionDefault
paramsNoOptional ingestion parameters
kb_nameYesKnowledge base name
file_nameYesName of the file
file_contentYesBase64 encoded file content

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so the description must disclose behavioral traits. It only says 'ingest a file' without explaining what ingestion entails (e.g., overwriting, appending, async processing, error behavior). The 'params' object is left undocumented.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single, concise sentence that packs the core function and required inputs with no wasted words. Front-loaded with the action and essential details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (4 parameters, nested object, no output schema), the description lacks many important aspects: supported file types, size limits, response behavior, success/failure indicators, async nature. It covers only the bare minimum.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with brief descriptions. The description reiterates the key inputs but adds no additional constraints, formats, or example values. For a 4-parameter tool with a nested object, more detail on 'params' would be helpful.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Ingest a file into an existing knowledge base') and lists required inputs (base64 content, filename, optional params). However, it does not differentiate from sibling ingest tools like ingest_knowledge_base_folder or ingest_knowledge_base_connector.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives (e.g., folder or connector ingest). Lacks when-to-use, when-not-to-use, or prerequisites beyond the required parameters.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

ingest_knowledge_base_connectorB

Ingest content into a knowledge base from a configured connector source.

ParametersJSON Schema
NameRequiredDescriptionDefault
kb_nameYesKnowledge base name
separatorNoChunk separator
chunk_sizeNoChunk size
source_nameNoSource name label
source_typeYesConnector source type
chunk_overlapNoChunk overlap
source_configNoConnector source configuration

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description bears full responsibility. It fails to disclose whether the operation is synchronous, whether it appends or overwrites, authorization requirements, or any side effects. The single sentence provides no behavioral context beyond the basic action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single 10-word sentence, which is concise and front-loaded with the key action. However, it could include more context without becoming verbose. Still, it earns its place by stating the purpose clearly with no fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 7 parameters including nested objects, no output schema, and many sibling tools, the description is too brief. It lacks context about the ingestion process, output expectations, and how it relates to other knowledge base tools. The description does not adequately compensate for the complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, so the schema itself documents all parameters. The description adds no additional semantic meaning about how parameters like 'separator', 'chunk_size', or 'source_config' affect the ingestion process. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Ingest content into a knowledge base') and the specific method ('from a configured connector source'). It distinguishes this tool from siblings like 'ingest_knowledge_base' and 'list_knowledge_base_connectors' by specifying the source type.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives (e.g., 'ingest_knowledge_base' or 'ingest_knowledge_base_folder'). No prerequisites or context for usage are mentioned, leaving the agent without decision-making support.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

ingest_knowledge_base_folderB

Ingest a local folder into a knowledge base with chunking options.

ParametersJSON Schema

max_file_size_bytesNoMaximum file size in bytes

TDQS

B3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must fully disclose behavior. It fails to mention side effects (e.g., overwriting existing data), permissions required, or whether ingestion is synchronous or asynchronous.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, which is concise but omits critical usage and behavioral context. It is not optimally structured for quick comprehension.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 11 parameters and no output schema, the description is insufficient. It does not explain return values, error handling, or idempotency, leaving the agent without key operational context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description adds no specific parameter semantics beyond the schema, only a vague reference to 'chunking options'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (ingest), the resource (local folder into a knowledge base), and adds 'with chunking options' to differentiate from similar sibling tools like 'ingest_knowledge_base'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like 'ingest_knowledge_base' or 'upload_knowledge_base'. No prerequisites or conditions for use are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

install_mcp_projectB

Install a project as an MCP server into a target client, optionally specifying transport.

ParametersJSON Schema
NameRequiredDescriptionDefault
clientYesTarget client (e.g. cursor, claude)
transportNoOptional transport
project_idYesProject ID (UUID)

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavioral traits. It indicates a state change (installing) but omits details about side effects (e.g., whether it overwrites existing configurations), authentication needs, error conditions, or what the response contains (no output schema). This lack of transparency makes it harder for an agent to anticipate outcomes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence that immediately conveys the tool's core purpose. It is front-loaded and contains no unnecessary words or redundancies.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's mutation nature and lack of output schema, the description should explain the result of installation (e.g., success indicator or server config). It also fails to mention prerequisites like project existence or permissions. The description is insufficient for an agent to fully understand the tool's effects and usage context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for all three parameters. The tool description adds only that transport is 'optional', which repeats the schema. It does not provide additional semantic meaning, such as valid transport values or how the client parameter affects behavior. Per the guidelines, with high schema coverage, a baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action 'install a project as an MCP server into a target client', which is specific and action-oriented. It distinguishes the tool from siblings like list_mcp_servers, create_mcp_server, and get_mcp_project_installed, making its unique purpose evident.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for installation tasks but does not explicitly state when to use versus alternatives like update_mcp_server or delete_mcp_server. No exclusions or prerequisites are mentioned, though the context of sibling tools gives some implicit guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

invoke_a2a_jsonrpcB

Invoke a flow via the A2A JSON-RPC endpoint (Langflow 1.11.0). The JSON-RPC envelope is a passthrough; validation lives server-side.

ParametersJSON Schema
NameRequiredDescriptionDefault
idNoJSON-RPC request ID
methodYesJSON-RPC method name
paramsNoJSON-RPC params (object or positional array)
flow_idYesFlow ID
jsonrpcNoJSON-RPC version (e.g. "2.0")

TDQS

B3.4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the passthrough nature and server-side validation, which adds some behavioral context beyond schema. However, without annotations, it fails to mention side effects, authorization needs, or rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no extraneous information. Front-loaded with the action (invoke) and resource (flow via A2A JSON-RPC). Highly concise and efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no output schema and no annotations, the description provides adequate context: what it does, the passthrough behavior, and where validation occurs. It could mention return format or prerequisites, but overall sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the description adds no additional meaning beyond the schema. The description mentions 'JSON-RPC envelope' but doesn't elaborate on parameters. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it invokes a flow via the A2A JSON-RPC endpoint and notes it's a passthrough. However, it does not distinguish from similar invocation tools like run_flow or predict_flow, which could cause confusion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. It mentions server-side validation but lacks when/when-not or usage context. Sibling tools include many flow-related methods, but no differentiation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

like_store_componentB

Like (or toggle like on) a Langflow Store component.

ParametersJSON Schema
NameRequiredDescriptionDefault
component_idYesStore component ID

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose all behavioral traits. It mentions 'toggle' implying mutation, but fails to describe side effects, required authentication, or what happens when already liked.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no fluff, front-loaded with action and resource. Every word is necessary.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no output schema and one parameter. Description does not explain return values or behavior (e.g., success message, toggled state). Incomplete for a toggle action.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the description adds no extra meaning beyond the existing parameter description 'Store component ID'. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description specifies the verb 'Like (or toggle like on)' and the resource 'Langflow Store component', clearly distinguishing it from siblings like get_user_likes or list_store_components.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when a user wants to like or toggle like on a component, but does not explicitly state when to use this tool versus alternatives like get_user_likes to check likes.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_a2a_agentsA

List available A2A (Agent-to-Agent) agents (Langflow 1.11.0). Requires server-side A2A enablement (LANGFLOW_A2A_ENABLED).

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.6/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, description carries full burden. It notes the requirement for LANGFLOW_A2A_ENABLED, but does not disclose response format or that it is a read-only operation. Partial transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with purpose, no waste. Efficiently conveys key information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple list tool with no parameters and no output schema, description is mostly complete. Could hint at what the list contains (e.g., agent cards or just names), but still adequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters and schema coverage 100%, so baseline 3 applies. Description does not need to add parameter info.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it lists available A2A agents, specifying a version and prerequisite. It implicitly distinguishes from sibling 'get_a2a_agent_card' by using 'list' vs 'get', but does not explicitly differentiate from 'invoke_a2a_jsonrpc'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage: when you need to list A2A agents. It mentions a prerequisite (server-side enablement), but does not provide when-not-to-use or alternative tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_api_keysA

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden but only mentions pagination. It omits details like ordering, filtering, or what member information is returned. Not misleading but insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no fluff. Efficient but could benefit from additional context without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Lacks details on return values (e.g., member IDs, names) and does not differentiate from sibling tools like get_authz_team. Minimal context for a tool with three parameters and no output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with parameter descriptions. The description adds 'with pagination,' which hints at limit/offset but doesn't provide extra meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the tool lists members of an authorization team with pagination, using a specific verb and resource. This distinguishes it from siblings like list_authz_teams and get_authz_team.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like add_authz_team_member or list_authz_teams. Does not specify required permissions or context.

list_flowsA

List Langflow flows with flexible filtering and pagination.

Purpose: Retrieve flows from your Langflow instance with optional pagination and organization filters. Essential for discovering available workflows, managing large flow collections, and browsing flows within specific folders.

Parameters:

  • page (optional, number, default: 1, min: 1): Page number for pagination

  • size (optional, number, default: 50, max: 100): Number of flows per page

  • folder_id (optional, UUID string): Filter flows within a specific folder

  • components_only (optional, boolean, default: false): Return only component flows (reusable flow components)

  • get_all (optional, boolean, default: true): Retrieve all flows ignoring pagination (use with caution for large datasets)

Returns: Array of FlowRead objects containing:

  • id (UUID): Unique flow identifier

  • name (string): Flow display name

  • description (string): Flow purpose description

  • folder_id (UUID): Parent folder if organized

  • user_id (UUID): Owner user identifier

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit when-to-use guidance (e.g., 'Call this before create_flow'), best practices (cache IDs, check parent_id), common errors with explanations, and a list of related tools with their purposes. This helps an agent decide when to invoke this tool over alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

kb_nameYesKnowledge base name

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. 'List' implies read-only, but the description does not explicitly state behavior (e.g., that the tool does not modify data, what happens if kb_name is invalid, or any rate limits).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is concise and front-loaded with the purpose. No wasted words, but it could be slightly expanded to cover return values or usage tips.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description should explain what the tool returns (e.g., list of chunks with properties). It does not mention return format, error handling, or pagination behavior beyond indicating it's optional. This is insufficient for a tool with four parameters and no output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, so the baseline is 3. The description adds 'with optional pagination and search' which reinforces the roles of page/limit/search parameters, but does not add new information beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('List') and resource ('chunks stored in a knowledge base'), and mentions optional pagination and search. However, it does not differentiate from the sibling tool 'preview_knowledge_base_chunks', which may have overlapping functionality.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives, such as 'preview_knowledge_base_chunks' or other listing tools. There is no mention of prerequisites (e.g., the knowledge base must exist) or when to use pagination/search.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_knowledge_base_connectorsA

List available knowledge base ingestion connectors.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the burden. It implies a read-only list operation but lacks details about authentication, rate limits, or edge cases like empty results.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with no extraneous information; concise and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple list tool, the description is adequate but does not specify return format (e.g., list of IDs and names) despite no output schema. It could provide more detail for completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist, and schema coverage is 100%, so the baseline is 4. The description adds no parameter information, which is acceptable given no parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists knowledge base ingestion connectors, with a specific verb and resource. It distinguishes from sibling tools like ingest_knowledge_base_connector and list_knowledge_bases.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives, such as prerequisites or context for ingestion workflows.

limitNoMaximum number of results
kb_nameYesKnowledge base name

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It states 'List ingestion runs' implying a read operation, but lacks details on behavior like what happens with missing kb_name, rate limits, or pagination type (page vs cursor).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise (6 words) with no filler. Every word is necessary and the structure is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple list tool, the description is minimally complete. However, it does not mention what is returned (e.g., run objects or counts) and there is no output schema to compensate, leaving some ambiguity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the input schema already describes all 3 parameters. The description adds 'with pagination' which hints at page/limit usage but does not add meaningful detail beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'List' and the resource 'ingestion runs for a knowledge base', which is specific and distinguishes it from sibling tools like 'list_knowledge_bases' (which lists bases) and 'get_knowledge_base_run' (which gets a single run).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions pagination but does not specify when to use this tool vs alternatives, nor does it provide prerequisites (e.g., needing kb_name) or context about when listing runs is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_knowledge_basesA

List all knowledge bases for Retrieval-Augmented Generation (RAG) workflows.

Purpose: Discover available knowledge bases containing document collections for RAG applications. Essential for understanding what document repositories are available, finding knowledge bases for flow integration, and managing document-based AI applications.

Parameters: None

Returns: Array of KnowledgeBaseInfo objects containing:

  • name (string): Knowledge base identifier/name (use this in get_knowledge_base or delete_knowledge_base)

  • description (string): Purpose and contents description

  • Additional metadata varies by knowledge base implementation (document count, vector store info, embedding model)

Usage Examples:

  1. List all knowledge bases: {}

Best Practices:

  • Call this before integrating knowledge bases into RAG flows to verify availability

  • Use knowledge base names in Langflow's Vector Store or RAG components

  • Document which flows use which knowledge bases for dependency tracking

  • Monitor knowledge base list to identify unused repositories for cleanup

  • Cache knowledge base names for flow configuration validation

  • Verify knowledge base exists before flow execution to avoid runtime errors

Common Errors:

  • Empty results: No knowledge bases configured (create knowledge bases in Langflow UI or via API)

  • Connection timeout: Check Langflow instance availability and vector store connectivity

  • "Knowledge base service unavailable": Vector store backend not configured or unreachable

Related Tools:

  • get_knowledge_base: Retrieve detailed information about specific knowledge base

  • delete_knowledge_base: Remove individual knowledge base when no longer needed

  • bulk_delete_knowledge_bases: Clean up multiple knowledge bases at once

  • create_flow: Build RAG flows using knowledge base names from this list

TDQS

A4.5/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. It describes return type and fields but does not explicitly state read-only behavior or side effects. Implies non-destructive listing but lacks explicit safety guarantees.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured with sections for purpose, parameters, returns, examples, best practices, errors, and related tools. Front-loaded with purpose. Slightly verbose but every section adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Completely covers the tool's usage, return values, best practices, and common errors. No output schema, so description adequately explains return structure. Covers integration context with flows and error handling.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters, so schema coverage is 100% trivially. Description adds full semantics by detailing the structure of the returned array (name, description, additional metadata).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states 'List all knowledge bases for Retrieval-Augmented Generation (RAG) workflows.' with specific verb and resource, and distinguishes from sibling tools like get_knowledge_base.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit guidance including usage examples, best practices, common errors, and related tools. Tells when to use (before integrating, verify availability) and mentions alternatives (get_knowledge_base for details).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_knowledge_bases_detailedA

List knowledge bases with detailed metadata (embedding config, chunk counts, etc.).

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full responsibility. It indicates the output includes detailed metadata but does not disclose any behavioral traits such as read-only nature, authorization requirements, rate limits, or side effects. The description is adequate for a simple list operation but lacks depth.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that conveys the essential information without redundancy. Every word serves a purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (no parameters, no output schema), the description is sufficiently complete. It clarifies what distinguishes this tool from its basic sibling. However, it could mention if pagination or filtering is available.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters with 100% schema coverage, so the description adds meaning by specifying the kind of metadata returned (embedding config, chunk counts, etc.). This is valuable context beyond the empty schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (list knowledge bases) and the distinguishing feature (detailed metadata including embedding config, chunk counts, etc.). It effectively differentiates from the sibling 'list_knowledge_bases' which presumably returns basic info.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for obtaining detailed metadata but does not explicitly state when to use this versus 'list_knowledge_bases' or other sibling tools. There is no mention of when not to use it or any specific prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_mcp_serversA

memory_base_idYesMemory base ID

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavioral traits. It only states the action and optional filter, omitting details about pagination, ordering, side effects (none expected), or rate limits. The agent lacks information about how the list is returned or if it is paginated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that immediately conveys the tool's purpose. Every word contributes meaning, with no redundancy or unnecessary details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description does not explain the return format or any prerequisites (e.g., memory base must exist). Since there is no output schema, the agent has minimal context about what the list output contains, making it incomplete for a list operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description adds no semantic value beyond what the schema already provides; it only repeats the session filter concept. No additional meaning for page/size parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'List' and the resource 'messages stored in a memory base', and specifies an optional filter by session. It effectively distinguishes this tool from siblings like 'list_memory_bases' and 'list_memory_base_sessions'.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence with no unnecessary words. It is front-loaded and efficient, though could add minimal additional context without harming conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description should at least hint at the return format. It does not specify whether a list of names or objects is returned. For a simple listing tool, this omission leaves the agent with incomplete information.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are no parameters, so schema coverage is 100%. The description does not add parameter information, but with zero parameters, the baseline is 4. No further detail is needed.

For a zero-parameter list tool without output schema, the description sufficiently conveys the operation, though it omits return details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist, so baseline is 4. Description correctly adds no param info as schema covers 100%.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'List all available profile pictures' uses a specific verb 'List' and resource 'profile pictures', clearly distinguishing it from the sibling 'get_profile_picture' which retrieves a single picture.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for browsing all pictures, and the sibling 'get_profile_picture' suggests alternative for specific pictures, but no explicit when-not or context is provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_projectsA

List all projects with optional pagination. Projects group related flows and resources.

ParametersJSON Schema
NameRequiredDescriptionDefault
pageNoPage number for pagination (default: 1)
sizeNoNumber of items per page (default: 50, max: 100)

TDQS

A3.7/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It states 'List all projects' implying a read-only operation, but does not disclose behavioral traits such as authorization needs, result scope (user's projects vs all), or any side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no wasted words. Every sentence provides value: the purpose and a brief definition of projects.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (list with optional pagination) and has no output schema. The description adequately explains the core function but lacks details on return format, sorting, or filtering, which could help the agent anticipate results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% (page and size are described). The description adds 'optional pagination' which echoes the schema but does not provide additional meaning. Baseline 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it lists all projects with optional pagination, and defines projects as grouping related flows and resources. This distinguishes it from siblings like get_project (single) and create_project.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions optional pagination but does not explicitly exclude cases (e.g., when to use get_project instead). However, the context implies it is for listing all projects, and no other project listing sibling exists, so guidance is clear but lacks explicit exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_starter_projectsA

List available starter project templates. Returns array of pre-built project templates that can be used to quickly bootstrap new Langflow projects.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It states the return type (array of templates) and purpose but lacks details on side effects, authorization, or data freshness. For a simple read-only list, this is adequate but not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no redundancy, front-loaded with the core action. Every sentence contributes meaning without waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a parameterless tool with no output schema or annotations, the description provides sufficient information to understand its function and return value. However, it could mention whether the list is comprehensive or if there are any limitations.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With zero parameters, schema coverage is trivially 100%. The description adds value by explaining the purpose (bootstrap projects), which gives semantic context beyond the empty schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'list' and the resource 'starter project templates'. It distinguishes from sibling tools like 'list_projects' by specifying that these are pre-built templates for bootstrapping Langflow projects.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives. The context of bootstrapping is implied but not contrasted with other list or create tools.

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It declares the tool's capabilities but lacks disclosure of behaviors like read-only nature, rate limits, pagination limits (beyond max:100), or data freshness. The description is adequate but not thorough.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that efficiently conveys the tool's purpose and key features without any redundant or ambiguous phrasing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 4 parameters, no output schema, and no annotations, the description covers the essential aspects. It could mention default sorting or result structure for completeness, but the current level is sufficient for a basic list operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all four parameters. The description summarizes the functionality ('pagination, filtering by tags, and search') but adds no new semantics beyond what the parameter descriptions provide.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Browse available components in the Langflow store' with specific verb and resource, and distinguishes itself from siblings like 'get_store_component' by highlighting pagination, filtering, and search features.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions supported operations (pagination, tags, search) but does not provide explicit guidance on when to use this tool versus alternatives like 'get_store_component' or 'list_store_tags'. No when-not or exclusion conditions are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_store_tagsB

List all available component tags in the store.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavioral traits, but it only states the basic action. It fails to mention pagination, ordering, rate limits, authentication needs, or what happens if no tags are available.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence with no extraneous information. While effective, it could be slightly enriched without harming conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (no parameters, no output schema), the description is adequate but minimal. It lacks context about the store, tag usage, or relation to other tools, leaving room for improvement.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so schema coverage is trivially 100%. The description does not need to add parameter info, earning a baseline score of 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must fully disclose behavior. It correctly implies a read operation, but does not mention potential rate limits, authentication needs, or what happens with empty results. For a list tool, this is adequate but not comprehensive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence of 12 words, front-loading the action and listing filter options without any redundant or vague phrasing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a straightforward list tool with no output schema, the description covers purpose, filters, and pagination. It does not explicitly state the return format (a list of traces), but the context is clear. The completeness is high given the low complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description summarizes filters into categories (flow, session, status, query, time range) and mentions pagination, adding slight value over the schema's individual descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'List' and the resource 'execution traces', and enumerates optional filters and pagination. It distinguishes from siblings like 'get_trace' (single trace) and 'delete_traces'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use for listing with filters and pagination, but does not explicitly contrast with sibling tools like 'get_trace' or 'delete_trace'. Still, the context of optional filters provides adequate guidance for typical listing scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_usersA

List all users in the Langflow instance. Admin-only endpoint. Supports pagination with skip and limit parameters. Returns array of user objects with id, username, email, and other profile information.

ParametersJSON Schema
NameRequiredDescriptionDefault
skipNoNumber of users to skip (default: 0)
limitNoMaximum number of users to return (default: 50, max: 100)

TDQS

A4.4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. Description discloses admin requirement and return structure, but does not mention idempotency, rate limits, or potential errors. Adequate for a read-only list operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences: purpose, constraints, and details. Front-loaded and no redundant information. Efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, but description includes return type and fields. Missing error conditions or authentication details, but overall sufficient for a simple listing tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers both parameters. Description adds context: pagination usage, limit max of 100, and return type (array of user objects with fields). Adds value beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'List all users in the Langflow instance' with a specific verb and resource. It distinguishes from siblings by focusing on users and is not duplicated among other list tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_variablesB

List all global variables. Variables store reusable values across flows.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description must carry the full burden. The verb 'List' implies a read-only operation, but the description does not explicitly state the absence of side effects, required permissions, or any rate limits. For a simple list operation, this is minimally adequate but lacks depth.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise, consisting of two short sentences. The first sentence provides the core action, and the second adds context. No extraneous words are present.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no parameters, no output schema, and no annotations, the description is minimal but covers the basic purpose. However, it lacks information about return format, pagination, or any filtering capabilities. It is adequate but has clear gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters, and the schema coverage is 100% (by default). The description adds no additional meaning to parameters beyond what the schema provides. The baseline of 3 is appropriate given the absence of parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'List' and the resource 'global variables', with an additional sentence explaining what variables are. This provides a specific purpose, but does not explicitly differentiate from sibling variable-related tools (e.g., create_variable, update_variable).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. There is no mention of context, prerequisites, or when not to use it. Sibling tools like create_variable and delete_variable imply different actions, but the description does not clarify this distinction.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

loginA

Authenticate with username and password. Returns access token, optional refresh token, and token type. Use the access token in subsequent API requests.

ParametersJSON Schema
NameRequiredDescriptionDefault
passwordYesPassword for authentication
usernameYesUsername for authentication

TDQS

A3.5/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the authentication method and returned tokens (access, refresh, token type), but lacks details on error handling, rate limits, token lifetimes, or security considerations. With no annotations provided, the description carries full burden and is minimally adequate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise with two sentences, front-loaded with the action verb 'authenticate'. No unnecessary words, every sentence contributes meaning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the return values (access token, refresh token, token type) partially, but does not explain token type or mention that this tool is typically the first step for authenticated requests. With no output schema, more detail would be beneficial.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the description adds no extra meaning beyond what the schema already provides. It merely repeats the need for username and password, so baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool authenticates with username and password and returns tokens. It is specific and identifies the resource (authentication) and action (return tokens). However, it does not differentiate from sibling tools like 'auto_login' or 'refresh_token'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for obtaining an access token for subsequent API requests, but it does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives like 'auto_login'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

logoutA

Logout and invalidate current authentication session. Clears authentication tokens and terminates the session.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4.4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description effectively discloses behavioral traits: invalidating session, clearing tokens, and termination. It does not explicitly mention prerequisites (e.g., being logged in) but the action is intuitively understood.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short sentences, front-loaded with the primary action. Every word is meaningful with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity (no parameters, no output schema), the description adequately explains the tool's effect. It could mention return value or idempotency, but for a logout action, it is sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist, and schema coverage is 100%. Baseline 4 applies as the description is not required to add parameter info. It correctly omits parameter details.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: to logout, invalidate the session, clear tokens, and terminate the session. It distinguishes from sibling auth tools like 'login' and 'auto_login' by focusing on ending authentication.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use this tool (to end a session) and is clear in context. However, it does not explicitly provide alternatives or when-not-to-use guidance, though the sibling tools make those alternatives obvious.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

migrate_monitor_sessionB

Migrate messages from old session ID to new session ID. Updates all messages from the old session to belong to the new session, effectively merging or renaming sessions. Useful for session continuity, combining split sessions, or correcting session identifiers.

ParametersJSON Schema
NameRequiredDescriptionDefault
new_session_idYesTarget session ID to migrate to
old_session_idYesOriginal session ID to migrate from

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must fully disclose behavioral traits. It mentions updating messages and merging/renaming sessions, but does not clarify whether the operation is destructive (e.g., old session deleted), if there are side effects on related data, or if authorization is needed. Critical details about what happens to the old session after migration are omitted.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two efficient sentences: first states the action and effect, second lists use cases. No redundant words, front-loaded with main purpose. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a data migration operation with no output schema, the description should cover return value, error conditions, and full lifecycle effects. It adequately states purpose and use cases but lacks details on what is returned (e.g., success status, count of migrated messages) and error scenarios (e.g., missing session IDs).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with both parameters described ('Original session ID to migrate from', 'Target session ID to migrate to'). The description adds a brief restatement but no additional meaning, constraints, or examples. Baseline score of 3 is appropriate given the schema already defines parameters clearly.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool migrates messages from old to new session ID, merging/renaming sessions. It mentions use cases (session continuity, combining splits, correcting identifiers). However, it does not explicitly differentiate from the sibling tool 'migrate_shared_session' which likely has a similar role for shared sessions, leaving ambiguity about scope.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides some guidance on when to use it (session continuity, combining split sessions, correcting identifiers) but lacks explicit when-not-to-use conditions, alternatives, or prerequisites (e.g., session existence, permission requirements).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

migrate_shared_sessionC

Migrate a shared session to a new session ID within a source flow.

ParametersJSON Schema

new_session_idYesNew session ID
source_flow_idYesSource flow ID

TDQS

C2.8/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It does not disclose whether the operation creates, updates, or deletes sessions, its reversibility, or required permissions. Insufficient for agent to understand behavioral implications.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence is efficient but lacks structure. It covers the primary action but omits important context, making it under-informative for a tool with required parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Minimal description does not explain what 'shared session' means, the outcome of migration, or side effects. Given no output schema, agent lacks complete context to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema describes all three parameters with 100% coverage. Description adds no additional meaning beyond the schema, meeting baseline but not improving understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the verb 'Migrate' and resource 'shared session' to a new session ID within a source flow. Distinguishes from siblings like migrate_monitor_session by specifying 'shared session', but does not elaborate on what 'within a source flow' entails.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like migrate_monitor_session or delete_shared_session. No prerequisites or conditions mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

flow_idYesFlow ID (UUID) to predict

TDQS

A3.6/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so the description carries full burden. It only states the basic function without disclosing side effects, auth requirements, or behavior differences of the legacy endpoint.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very concise with two short sentences, front-loaded with the legacy tag, containing no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite minimal complexity, the description lacks details on return values, error cases, or when to use the legacy version. It is incomplete for an agent to fully understand the tool's behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the description merely restates the schema terms (inputs, tweaks) without adding new meaning, resulting in baseline score.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it is a legacy predict endpoint for backward compatibility, predicting flow output with inputs and optional tweaks. It distinguishes itself from siblings by being the legacy version, using specific verbs and resources.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions 'backward compatibility,' implying use for old systems, but does not explicitly name alternatives like run_flow. The context of sibling tools provides some guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Preview how a file would be chunked for knowledge base ingestion. Provide base64 file content, filename, and optional chunking params.

ParametersJSON Schema
NameRequiredDescriptionDefault
paramsNoOptional chunking parameters
file_nameYesName of the file
file_contentYesBase64 encoded file content

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided. The description indicates it's a preview (non-destructive, read-only), but does not disclose behavioral traits such as resource consumption, rate limits, or whether the tool actually processes the file (which could be expensive). Basic transparency but lacks depth.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with two sentences, front-loading the purpose and essential inputs. Every sentence is necessary and there is no fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description lacks details about return values (no output schema), error handling, or prerequisites like supported file types. Given the tool's complexity (previewing chunks) and missing annotations, the description could be more complete to inform the agent about expected outcomes.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for all three parameters. The description adds 'Provide base64 file content, filename, and optional chunking params', which aligns with the schema but does not elaborate on 'optional chunking params' (e.g., chunk size, overlap). Minimal added value beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: previewing how a file would be chunked for knowledge base ingestion. It uses a specific verb ('Preview') and resource ('how a file would be chunked'), distinguishing it from sibling tools like 'ingest_knowledge_base' or 'upload_knowledge_base' which perform actual ingestion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for testing chunking before actual ingestion ('Preview'), but does not explicitly state when to use this tool vs alternatives or provide exclusion criteria. Clear context is given, but no 'when not to use' or alternative references.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

process_flowB

Legacy process endpoint for backward compatibility. Processes a flow with inputs and optional tweaks.

ParametersJSON Schema
NameRequiredDescriptionDefault
inputsNoInput values for the flow
tweaksNoComponent-specific parameter overrides
flow_idYesFlow ID (UUID) to process

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavioral traits. It only mentions processing with inputs and tweaks, omitting side effects, permissions, return value, or any operational details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with the legacy badge, conveying essential purpose efficiently. However, it could incorporate more useful information without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and no annotations, the description should provide more context about side effects, return values, or usage scenarios. It only covers purpose, missing critical operational details for an AI agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the description does not need to add much. It mentions 'inputs' and 'optional tweaks,' but adds no meaning beyond the schema descriptions already present.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool processes a flow with inputs and optional tweaks, and labels it as a legacy endpoint for backward compatibility, distinguishing it from modern alternatives like run_flow without naming them explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for backward compatibility only ('Legacy process endpoint'), but does not explicitly name which modern tool to use instead or specify when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

refresh_tokenB

Refresh authentication token using refresh token. Returns new access token and optionally a new refresh token.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It discloses the tool returns a new access token and optionally a new refresh token, but does not specify behavior on expired or invalid tokens, side effects on authentication state, or error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no wasted words. It effectively conveys the tool's purpose and output succinctly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple token refresh tool with no parameters, the description covers its operation and return values. However, it lacks mention of error conditions, prerequisites, or security implications. Still, it is mostly complete given the tool's simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has zero parameters, so schema description coverage is 100%. The description adds no parameter info beyond the schema, but no parameters exist. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool refreshes an authentication token using a refresh token, specifying it returns a new access token and optionally a new refresh token. This distinguishes it from sibling tools like login or auto_login, which handle initial authentication.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for token refresh but provides no explicit context on when to use it vs alternatives, prerequisites (e.g., valid refresh token), or when not to use it. No guidance is given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

regenerate_memory_baseC

Regenerate a memory base, rebuilding its stored memories.

ParametersJSON Schema
NameRequiredDescriptionDefault
memory_base_idYesMemory base ID

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It only says 'rebuilding its stored memories' but does not clarify side effects, prerequisites, or whether it is destructive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with a single sentence and no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, yet the description does not hint at return values (e.g., success status). The description feels incomplete for a rebuild operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter 'memory_base_id' is described in the schema. The description adds no extra meaning beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (regenerate) and the resource (memory base), but it does not differentiate from sibling tools like 'flush_memory_base' or 'update_memory_base'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives or when not to use it. The description does not provide context for appropriate usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

register_userB

Register a new user with Langflow using their email address.

ParametersJSON Schema
NameRequiredDescriptionDefault
emailYesEmail address to register

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so the description carries full burden. It fails to disclose important behaviors such as whether it sends a verification email, requires unique email, or creates default settings. A registration action typically involves side effects that should be described.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence with no unnecessary words, efficiently conveying the core purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given one parameter and no output schema, the description lacks completeness. It does not explain return values (e.g., user object, confirmation), error conditions, or registration flow steps like uniqueness checks.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the description merely paraphrases the schema ('using their email address'). No additional semantics beyond what the JSON schema already provides for the single email parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (register) and the resource (new user) with the method (using email address). It effectively distinguishes from sibling tools like 'create_user' or 'list_users' by specifying registration.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like 'create_user'. Missing prerequisites (e.g., admin permissions, existing session), and not specifying that registration is for first-time users.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

reload_extension_bundleB

Reload an extension bundle (requires LANGFLOW_ENABLE_EXTENSION_RELOAD on the server).

ParametersJSON Schema
NameRequiredDescriptionDefault
bundle_nameYesBundle name to reload
extension_idYesExtension ID

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description lacks behavioral details beyond the act of reloading. With no annotations provided, it should disclose effects such as whether the reload is synchronous, what state changes occur, or if existing sessions are affected. The single word 'Reload' implies mutation but no further transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that includes the essential purpose and a critical precondition. Every word serves a purpose, and there is no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given good schema coverage, no output schema, and no annotations, the description minimally covers the tool's action and a key requirement. However, it lacks context on what triggers the reload, confirmation, or error states, leaving some gaps for a complete understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents both parameters adequately. The description adds no additional meaning to the parameters, so the score is at the baseline of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Reload' and the resource 'extension bundle'. It adds the server configuration requirement, which distinguishes it from simply guessing the function. However, it closely mirrors the tool name without additional context.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides a precondition ('requires LANGFLOW_ENABLE_EXTENSION_RELOAD on the server'), which helps the agent decide when the tool is available. It does not, however, mention when not to use it or suggest alternative tools for similar tasks.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

remove_authz_team_memberB

Remove a user from an authorization team.

ParametersJSON Schema
NameRequiredDescriptionDefault
team_idYesTeam ID
user_idYesUser ID to remove

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must reveal behavioral traits. It only mentions 'Remove', implying mutation, but does not disclose whether removal is reversible, what happens if the user is not a member, or any permission requirements. The description is too sparse to inform an agent of side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no unnecessary words, making it concise. However, it may be too brief; slightly more detail would improve usefulness without losing conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, no annotations, and only two parameters, the description is insufficient. It omits return values, error conditions, and any contextual constraints, leaving an agent with inadequate information for confident invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already defines team_id and user_id. The description adds no further meaning beyond the tool's action, earning the baseline score of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Remove' and the resource 'user from an authorization team', distinguishing it from sibling tools like 'add_authz_team_member' and 'list_authz_team_members'. It is specific and unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives, nor are there prerequisites or exclusions. Given many sibling tools in the authz domain, such as add_team_member or list_team_members, the description offers no context for appropriate usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rename_file_v2C

Rename a user-scoped file via /api/v2/files.

ParametersJSON Schema
NameRequiredDescriptionDefault
nameYesNew file name
file_idYesFile ID

TDQS

C2.6/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, and the description fails to disclose any behavioral traits. It does not mention whether the operation is destructive, if it requires specific permissions, or what happens to the file's metadata. The description adds no value beyond the name.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Very concise single sentence, but includes an irrelevant API endpoint ('via /api/v2/files') that adds no value for an AI agent. Could be improved by removing that detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple rename tool with 2 parameters, the description is incomplete. It doesn't explain return values, error conditions, or constraints like name uniqueness. Agents lack information to handle the tool properly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with clear parameter descriptions. The description adds minimal extra meaning (just 'user-scoped' and API path). Baseline 3 is appropriate as the schema does most of the work.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the action (rename) and resource (file), but the addition of the API endpoint is extraneous. It distinguishes from sibling file operations but could be more specific about scope (e.g., 'owned by the current user').

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives, nor any prerequisites or conditions. Agents receive no help deciding between rename_file_v2 and other file operations.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

replace_flowA

Replace an entire flow (PUT) with new content. Overwrites name, description, data, and folder for the given flow ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
dataNoOptional flow data/configuration
nameYesNew flow name
flow_idYesFlow ID (UUID) to replace
folder_idNoOptional folder ID (UUID)
descriptionNoOptional flow description

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so description must convey behavioral traits. It mentions overwriting fields but lacks details on side effects, authorization needs, or behavior when optional parameters are omitted (e.g., will fields be cleared?).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero waste. The first sentence states the action and HTTP method; the second lists overwritten fields. Front-loaded and efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 5 parameters (including nested objects) and no output schema, the description is adequate for core purpose but fails to explain return values or the effect of omitting optional parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. Description adds context (PUT, overwrites) but does not significantly enhance parameter meaning beyond the schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool replaces an entire flow using PUT, overwriting name, description, data, and folder. It uses specific verbs and resources, distinguishing it from sibling tools like update_flow (partial update).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for full replacement (PUT), but does not explicitly state when to use this vs. alternatives like update_flow, nor provides when-not-to-use guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

reset_agentic_sessionB

Reset an agentic session, optionally targeting a specific session ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idNoSession ID to reset

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavioral traits. It only states 'reset' without explaining side effects (e.g., memory cleared, tokens invalidated, impact on ongoing workflows). The description is insufficiently transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence of 12 words, efficiently conveying the purpose and optional parameter. It is front-loaded and contains no unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of output schema and annotations, the description should explain return values and behavioral context. It fails to do so, leaving the agent uncertain about what happens after resetting a session.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema covers 100% of parameters with descriptions. The tool description mentions 'session ID' but adds no additional meaning beyond the schema. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'reset' and the resource 'agentic session', and mentions optional targeting of a session ID. It is specific and distinguishable from sibling tools like 'get_session' or 'delete_monitor_sessions'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It does not explain scenarios or exclusions, such as when to reset vs. stop a workflow or delete a session.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

reset_user_passwordA

Reset password for a specific user. Admin-only endpoint. Requires user ID and new password (minimum 8 characters). Returns updated user object.

ParametersJSON Schema
NameRequiredDescriptionDefault
user_idYesUser ID (UUID) to reset password for
new_passwordYesNew password (minimum 8 characters)

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description discloses key behaviors: admin-only access, requires user ID and new password, and returns updated user object. Absence of side effects or rate limits is acceptable for a simple reset tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences cover purpose, access constraint, and required inputs/outputs with no wasted words. Front-loaded with action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has 2 parameters, no output schema, and low complexity. Description sufficiently explains admin requirement, input expectations, and return value, making it complete for agent usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema describes both parameters with UUID and minLength; description adds 'minimum 8 characters' but is largely redundant. Since schema coverage is 100%, baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Reset password for a specific user' with the verb 'reset' and resource 'password'. It distinguishes from siblings like 'update_user' by specifying a targeted action.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly notes 'Admin-only endpoint', guiding agents to use only with admin credentials. Does not mention alternatives or non-admin scenarios, but the admin constraint provides clear usage context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

resume_workflowA

Resume a paused human-in-the-loop workflow with a decision payload (Langflow 1.11.0). The decision payload is a passthrough; validation lives server-side.

ParametersJSON Schema
NameRequiredDescriptionDefault
job_idYesWorkflow job ID
decisionYesHITL decision payload

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It discloses that the decision payload is a passthrough and that validation occurs server-side, which is important behavioral context. However, it does not mention auth requirements, rate limits, or what side effects occur beyond resuming.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with purpose and version, followed by a behavioral note. Every sentence is meaningful; no verbosity or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with 2 parameters and no output schema, the description explains action and payload, but does not mention what the tool returns (e.g., status, workflow result) or any prerequisites (e.g., workflow must exist and be paused). It's slightly incomplete for an agent to fully anticipate the outcome.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema covers both parameters with descriptions. The description adds value by explaining that 'decision' is a passthrough and server-validated, which goes beyond the schema's 'HITL decision payload'. For job_id, no additional detail, but overall adds meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Resume'), resource ('paused human-in-the-loop workflow'), and includes a version context. It distinguishes itself from sibling workflow tools like 'run_workflow' or 'stop_workflow' by specifying the target state (paused) and the required payload (decision).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when a workflow is paused and needs a decision, but does not explicitly state when not to use it or mention alternatives. The context is clear enough for an agent to infer appropriate usage, but lacks explicit exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

run_flowA

    • tweaks (optional, object): Component-specific parameter overrides (key: component_id, value: parameter object)

  • context (optional, object): Request context passed alongside the input request

  • stream (optional, boolean, default: false): Streaming is currently rejected by this MCP client because streamed responses are not JSON serializable

Returns: RunResponse object containing:

  • outputs (array): Flow execution results from output components

  • session_id (string): Unique session identifier for conversation continuity

  • Additional fields vary by flow configuration (message, data, artifacts)

Usage Examples:

  1. Simple execution: { flow_id_or_name: "my-chatbot", input_request: { input_value: "Hello" } }

  2. With output type: { flow_id_or_name: "data-processor", input_request: { input_value: "data", output_type: "json" } }

  3. With context: { flow_id_or_name: "llm-chat", input_request: { input_value: "Explain AI" }, context: { tenant: "acme" } }

  4. With tweaks: { flow_id_or_name: "flow-uuid", input_request: { input_value: "test", tweaks: { "component-id": { temperature: 0.7 } } } }

Best Practices:

  • Use flow ID (UUID) for production; names may change or conflict

  • Build flow first with build_flow to ensure it's valid before execution

  • Leave stream false; this MCP client currently returns JSON tool responses only

  • Cache session_id for multi-turn conversations to maintain context

  • Set appropriate timeout values for long-running flows

  • Test flows with various inputs before production deployment

  • Use tweaks sparingly; prefer configuring flows in Langflow UI

Common Errors:

  • "Flow not found": Verify flow_id_or_name exists using list_flows

  • "Flow has not been built": Run build_flow before executing

  • "Invalid input configuration": Ensure input_request matches flow's expected inputs

  • "Component configuration error": Check tweaks object matches component IDs and parameter names

  • "Execution timeout": Flow took too long; increase timeout or optimize flow

  • "Missing required input": Flow expects input_value but none provided

Related Tools:

  • build_flow: Compile flow before execution to validate structure

  • get_flow: Inspect flow structure to understand required inputs

  • get_build_status: Check build completion before running flow

  • trigger_webhook: Alternative execution method via webhook endpoint

  • list_flows: Find available flows to execute

TDQS

A4.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Without annotations, the description carries the full burden. It explains synchronous and streaming modes (noting stream rejection), what returns (RunResponse object), and lists common errors. However, it doesn't discuss side effects, state changes, or idempotency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (Purpose, Parameters, Returns, Usage Examples, Best Practices, Common Errors, Related Tools). It is front-loaded with the purpose. However, it is somewhat verbose; could be trimmed without losing clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of 4 parameters including a nested object and no output schema, the description is very complete. It covers inputs, behavior, limitations (streaming), error handling, and related tools. The agent has sufficient information to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage but the description adds significant value by explaining each sub-parameter of input_request in detail and providing usage examples. This goes beyond the schema's brief descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Execute a Langflow flow with inputs and retrieve execution results.' It uses a specific verb (execute) and resource (flow), and distinguishes it from siblings like build_flow, get_flow, and trigger_webhook.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use the tool (e.g., testing flows, integrating workflows) and when not to (e.g., build first with build_flow, verify flow existence with list_flows). It includes best practices, common errors, and related tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

run_flow_advancedC

Advanced flow execution with full parameter control including tweaks, input/output types, session management, and streaming. Supports both flow UUID and flow name.

ParametersJSON Schema
NameRequiredDescriptionDefault
streamNoEnable streaming mode (default: false)
tweaksNoComponent-specific parameter overrides
user_idNoUser ID (UUID) for user-scoped execution
input_typeNoType of input (e.g., "chat", "text")
session_idNoSession ID for conversation continuity
input_valueNoInput value for the flow
output_typeNoExpected output type (e.g., "chat", "text", "json")
flow_id_or_nameYesFlow ID (UUID) or flow name to execute
output_componentNoSpecific output component to retrieve results from

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavioral traits. It mentions capabilities but does not describe side effects (e.g., state changes), error behavior, authentication needs, or defaults. For a complex execution tool, this is insufficient for an agent to anticipate behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: two sentences covering all major capabilities. It is front-loaded with the core purpose and immediately follows with the identifier support detail. No extraneous words or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (9 parameters, nested objects, no output schema), the description lacks critical context. It does not explain return values, error conditions, or how to use parameters together. An agent would need more information to invoke this tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the description does not need to explain parameter meaning in detail. The description reinforces categories like tweaks and streaming but adds no additional semantic value beyond the schema. This meets the baseline for high coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: advanced flow execution with full parameter control. It mentions specific features like tweaks, input/output types, session management, and streaming. However, it does not explicitly differentiate from similar sibling tools like 'run_flow', relying on the name 'advanced' to imply distinction.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives such as 'run_flow' or 'run_flow_session'. There are no prerequisites, constraints, or scenarios where the tool is not appropriate, leaving the agent without decision-making context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

run_flow_sessionB

Execute a flow with session-based state management. Maintains conversation context across multiple calls using the same session ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
streamNoStreaming is currently rejected by this MCP client
tweaksNoComponent-specific parameter overrides

input_valueNoInput value for the flow
output_typeNoExpected output type (e.g., "chat", "text", "json")
flow_id_or_nameYesFlow ID (UUID) or flow name to execute
output_componentNoSpecific output component to retrieve results from

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Only states session persistence; missing details on side effects, auth needs, rate limits, or error handling. Does not mention behavior of stream parameter noted in schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, front-loaded with purpose, second adds key distinguishing feature. No fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite 9 complex parameters (including nested objects) and no output schema, description is too brief. Lacks details on return values, error handling, session lifecycle, or interaction with other parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All 9 parameters have schema descriptions (100% coverage). Description adds no additional parameter context beyond what schema provides, so baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the tool executes a flow with session-based state management, distinguishing it from similar tools like run_flow. Verb and resource are explicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives like run_flow or run_flow_advanced. Usage context is implied through session mention but no when-not-to-use or prerequisite info.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

run_public_workflowB

Run a public (unauthenticated-eligible) workflow (Langflow 1.11.0). Stream-only execution; streaming is not incrementally surfaced.

ParametersJSON Schema
NameRequiredDescriptionDefault
inputsNoWorkflow inputs
streamNoStream the run
flow_idYesFlow ID
globalsNoRequest-level global variables

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It mentions 'stream-only execution' and 'streaming is not incrementally surfaced', which is ambiguous and does not fully clarify the streaming behavior or side effects. It omits details on permissions, rate limits, or error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise with two clauses in one sentence. It is front-loaded and free of unnecessary words. However, the second part could be split into a separate sentence for improved readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 4 parameters, no output schema, and no annotations, the description is too brief. It does not explain return values, error handling, or the exact behavior of the stream parameter despite mentioning it. The tool's complexity warrants more detail to be fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already covers all 4 parameters with descriptions (100% coverage). The description adds minimal meaning beyond the schema, only providing context that this tool is for public workflows and stream-only execution, which indirectly relates to the stream parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Run' and the resource 'public (unauthenticated-eligible) workflow', specifying the Langflow version and the stream-only execution mode. This distinguishes it from sibling tools like run_workflow, which presumably handles authenticated workflows.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for public workflows by noting 'unauthenticated-eligible', but does not explicitly state when to use this tool over alternatives like run_workflow. No exclusions or context are provided. The guidance is implicit and minimal.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

run_workflowB

Run a workflow (V2) for a flow with inputs. Supports streaming and background execution.

ParametersJSON Schema
NameRequiredDescriptionDefault
inputsNoWorkflow inputs
streamNoStream the run
flow_idYesFlow ID
globalsNoRequest-level global variables (Langflow 1.10.0)
backgroundNoRun in background

TDQS

B3.4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the burden. It discloses support for streaming and background modes but does not explain behavioral aspects like whether it is read-only or mutating, or what happens after background execution.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence, front-loading the main action and adding key features (streaming, background) without unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (5 parameters, nested objects) and absence of an output schema, the description provides no information about return values, result structure, or how to handle background runs, leaving important gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already describes all parameters. The description adds no additional parameter context beyond the schema, meeting the baseline for high coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it runs a workflow (V2) with inputs and mentions support for streaming and background execution. However, it does not differentiate from sibling tools like run_flow or run_flow_advanced, which have similar purposes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for workflows requiring streaming or background execution but provides no explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives among the many sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

save_store_api_keyA

Save the Langflow Store API key for the current user so store operations are authenticated.

ParametersJSON Schema
NameRequiredDescriptionDefault
api_keyYesLangflow Store API key

TDQS

A3.7/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description must disclose behavioral traits. It only states 'Save' without explaining whether the key is overwritten, if authentication is required, or what happens on error. This is a significant gap for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence (15 words) with no wasted words. It is front-loaded and efficiently communicates the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity (1 param, no output schema), the description is adequate but incomplete. It lacks details on idempotency, overwriting behavior, and prerequisite steps (e.g., needing a prior login).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% (one parameter with description). The description adds context that the key is saved 'for the current user so store operations are authenticated', which adds meaning beyond the parameter name and schema description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Save' and the resource 'Langflow Store API key', with the purpose for the current user to authenticate store operations. It differentiates from siblings like 'check_store_api_key' and 'list_store_components'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage before store operations but does not explicitly state when to use this tool vs alternatives like 'check_store_api_key'. No exclusions or alternative recommendations are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

set_default_modelB

model_nameYesModel name
model_typeYesModel type

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description must carry the burden. It only says 'Set,' implying mutation, but does not disclose side effects, permissions, or reversibility.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with purpose, no extraneous words. Highly concise and well-structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, no annotations. Description does not explain return values, prerequisites, effects on existing defaults, or error cases. Incomplete for a mutation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 100% coverage with descriptions, but they are minimal (single words). Description adds no extra meaning beyond parameter names; no enums or valid values are indicated.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the action (Set), resource (default model), and scope (for a given model type). It effectively distinguishes from sibling tools like get_default_model and delete_default_model.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. Sibling tools exist (get, delete) but no context is provided for selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

set_enabled_modelsC

Enable or disable specific models by provider and model ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
modelsYesArray of model status updates

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description bears the full burden of behavioral disclosure. It implies a state change ('Enable or disable') but offers no details on side effects, reversibility, permission requirements, or whether the operation is atomic. This is insufficient for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that efficiently communicates the core purpose. However, it could be expanded with a brief note on effects without sacrificing conciseness, as the tool is a mutation with no annotations.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of output schema and annotations, the description should provide more context about the outcome, such as whether it returns a confirmation or updated model list. It also does not address error conditions or the scope of the change, making it incomplete for a mutation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage with descriptions for all parameter fields. The tool description does not add any additional meaning beyond what the schema already provides, so a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Enable or disable' and the resource 'specific models by provider and model ID'. It distinguishes this tool from sibling tools like list_enabled_models, but could be more explicit about whether it updates existing model entries or sets new ones.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like validate_model_provider or list_enabled_models. There is no mention of prerequisites, such as requiring the model to already exist, or exclusions for certain scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

NameRequiredDescriptionDefault
job_idYesWorkflow job ID to stop

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description must carry full behavioral burden. It states the core action but omits details: what happens if job is already stopped, permissions needed, side effects, or irreversibility.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no extraneous words. Efficient and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a simple stop action, but lacks return value description and prerequisites. Without output schema, a brief note on response would help.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and description adds no further meaning beyond the schema's 'Workflow job ID to stop'. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the action (stop), resource (workflow job), and how (by job ID). Differentiates from siblings like run_workflow and resume_workflow.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies use when you have a running workflow job ID, but lacks explicit when-not-to-use or alternatives. Could mention that job must be running or how to obtain job ID.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

stream_vertex_buildA

⚠️ DEPRECATED: This endpoint is deprecated in Langflow API 1.6.4 and will be removed in a future version. Use "get_build_status" tool with event_delivery="streaming" to monitor build progress.

Stream real-time build events for a specific vertex. Provides live updates during vertex build process using server-sent events (SSE). Essential for monitoring long-running component builds, debugging build failures in real-time, and providing live build status to users.

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID (UUID) containing the vertex
vertex_idYesVertex ID to stream build events for

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears full responsibility. It discloses the non-destructive streaming behavior, SSE protocol, and deprecation. However, it does not mention authentication or rate limits, but these are typical and not critical for a streaming tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with two concise paragraphs: the first delivers the critical deprecation warning and alternative, the second explains usage and purposes. No extraneous text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description should clarify the SSE event format. It mentions 'live build events' but does not specify the structure of events. The alternative tool reference helps, but the response format is left vague, reducing completeness for a streaming tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%; both parameters are fully described in the schema (flow_id and vertex_id). The description adds no additional meaning beyond the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool streams real-time build events for a specific vertex, providing live updates via SSE. It explicitly differentiates from 'get_build_status' and other siblings by focusing on streaming during the build process.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly states the tool is deprecated and provides the exact alternative ('get_build_status' with event_delivery='streaming'). It also explains when to use this tool: for monitoring long-running component builds, debugging, and providing live status.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It does not disclose whether the test is destructive, what side effects occur, or what success/failure looks like. Minimal behavioral insight.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The single sentence is brief but omits critical information, indicating under-specification rather than effective conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no annotations, the description fails to explain what 'test' entails, expected results, or error conditions. Incomplete for a tool with parameters and nested objects.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Although schema coverage is 100%, the description adds no additional meaning beyond the schema's parameter descriptions. It repeats the tool's purpose without elaborating on the parameters.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 2 parameters, nested objects, no output schema, and no annotations, the description is too minimal. It does not explain the outcome (e.g., result, status) or error handling, leaving significant gaps for an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with parameter descriptions already included. The description adds no extra meaning beyond what the schema provides, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'trigger' and the resource 'flow via webhook endpoint'. It distinguishes itself from sibling flow execution tools like run_flow or process_flow by specifying webhook-based execution.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'Simplified API for webhook-based flow execution' implies a simpler alternative but does not explicitly state when to use this tool versus alternative flow execution tools or provide prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_authz_roleB

Update an existing authorization role by ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
nameNoRole name
role_idYesRole ID
descriptionNoRole description
permissionsNoPermission identifiers
parent_role_idNoParent role ID for inheritance

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Only mentions 'Update', which implies mutation but does not disclose permissions, reversibility, side effects, or auth requirements. Lacks behavioral context for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no wasted words. Could be improved by front-loading key behavioral info, but it is appropriately concise for a simple update.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, so return value behavior is unexplained. Parameters are fully covered by schema. Missing behavioral details like idempotency or success/failure responses. Adequate but not complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for all 5 parameters. Description adds no additional meaning beyond what the schema already provides, baseline of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states 'Update an existing authorization role by ID', using specific verb (update) and resource (authorization role). Differentiates from siblings like create_authz_role and delete_authz_role.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use or when not to use this tool. Implies use for updating existing roles, but no alternatives or exclusions mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_authz_shareB

Update the permission level of a resource share.

ParametersJSON Schema
NameRequiredDescriptionDefault
share_idYesShare ID
permission_levelYesPermission level: read, write, execute, or admin

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must convey all behavioral traits. It only states 'Update the permission level' but does not disclose whether the operation is destructive, requires authorization, or what the side effects are. There is no mention of return value or mutation behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is concise and directly states the tool's purpose. It is appropriately brief but could benefit from additional context without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple nature of the tool (two parameters, no output schema, no annotations), the description is minimally adequate. However, it lacks information about the return value or any potential side effects, which would make it more complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage with descriptions for both parameters (share_id and permission_level). The description adds no extra meaning beyond the schema, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the specific verb 'Update' and clearly identifies the resource as 'permission level of a resource share'. It distinguishes itself from sibling tools like create_authz_share, delete_authz_share, get_authz_share, and list_authz_shares.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives such as create_authz_share or delete_authz_share. It lacks context about scenarios or prerequisites for updating a share's permission level.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with no extraneous information, front-loads the essential purpose effectively.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Lacks specification of return value, error conditions, or constraints; for a mutation tool with no output schema and no annotations, this is incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with parameter descriptions; the description does not add additional meaning beyond what the schema provides, meeting the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action 'Update' and the resource 'authorization team' plus identifier 'by ID', distinguishing it from create and delete sibling tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives like patch or create; usage is implied but not detailed.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_custom_componentB

Update a custom component template field, recomputing the frontend node based on the provided code and field changes.

ParametersJSON Schema

codeYesCustom component source code
fieldYesTemplate field being updated
templateYesCurrent component template
tool_modeNoOptional tool-mode flag
field_valueNoNew value for the field (any JSON type)
frontend_nodeNoOptional current frontend node definition

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden for behavioral disclosure. It indicates mutation ('update') and a side effect ('recomputes the frontend node'), but does not disclose aspects like idempotency, destructive potential, authorization needs, or error conditions. This is insufficient for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that efficiently conveys the action and key side effect. No unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite moderate complexity (6 parameters, nested objects, no output schema), the description does not explain return values, optional parameters like tool_mode and frontend_node, or error states. This leaves gaps for an agent using the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions per parameter. The description adds overall context by linking code and field changes to the recomputation, but does not provide additional detail beyond the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool updates a custom component template field and recomputes the frontend node, specifying the verb (update), resource (custom component template field), and side effect. This distinguishes it from create_custom_component and other update tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives like create_custom_component. It does not mention prerequisites, exclusions, or typical scenarios, leaving the agent to infer context from the tool name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_flowA

Modify existing flow properties, configuration, or organization.

Purpose: Update flow metadata (name, description), modify flow structure (nodes, edges, components), or reorganize flows into different folders. Essential for maintaining flows, fixing configurations, renaming workflows, and managing project organization over time.

Parameters:

  • flow_id (required, UUID string): Unique identifier of flow to update (from list_flows or get_flow)

  • name (optional, string, max: 255 chars): New display name for the flow

  • description (optional, string): Updated purpose and functionality description

  • data (optional, object): New flow structure with nodes, edges, and component configurations

  • folder_id (optional, UUID string): Move flow to different folder (use list_folders for valid IDs, null for root level)

Returns: FlowRead object containing:

  • id (UUID): Flow's unique identifier (unchanged)

  • name (string): Updated flow name

  • description (string): Updated description

  • folder_id (UUID): New folder location

  • user_id (UUID): Owner identifier

  • created_at (ISO timestamp): Original creation time (unchanged)

  • updated_at (ISO timestamp): Timestamp of this update

  • data (object): Complete updated flow structure

Usage Examples:

  1. Rename flow: { flow_id: "flow-uuid", name: "Improved Customer Bot" }

  2. Update description: { flow_id: "flow-uuid", description: "Processes customer inquiries with sentiment analysis" }

  3. Move to folder: { flow_id: "flow-uuid", folder_id: "folder-uuid" }

  4. Move to root: { flow_id: "flow-uuid", folder_id: null }

  5. Update structure: { flow_id: "flow-uuid", data: { nodes: [...], edges: [...] } }

  6. Rename and move: { flow_id: "flow-uuid", name: "New Name", folder_id: "folder-uuid" }

Best Practices:

  • Get current flow data with get_flow before updating to avoid overwriting changes

  • Only specify fields you want to change (partial updates supported)

  • Rebuild flow with build_flow after data modifications to validate changes

  • Use descriptive names and descriptions for team collaboration

  • Update description when flow functionality changes significantly

  • Move flows to appropriate folders to maintain organization

  • Verify folder_id exists before moving (use list_folders)

  • Update flow name if purpose or functionality changes

Common Errors:

  • "Flow not found": flow_id doesn't exist or was deleted (verify with list_flows)

  • "Flow name already exists": Choose unique name within target folder

  • "Invalid folder ID": folder_id is not valid UUID (use list_folders to get valid IDs)

  • "Folder not found": Specified folder_id doesn't exist

  • "Invalid flow data structure": data object doesn't match Langflow schema

  • "Concurrent modification": Flow was updated by another user (re-fetch with get_flow)

  • "flow_id is required": Must provide flow_id parameter

  • "Unauthorized": API key lacks permission to modify this flow

Related Tools:

  • get_flow: Retrieve current flow state before updating

  • build_flow: Validate flow after data modifications

  • list_flows: Find flow_id for flows to update

  • list_folders: Get valid folder_id values for reorganization

folder_idNoNew folder ID
descriptionNoNew description for the flow

TDQS

A4.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, but the description covers mutation nature, partial updates, need for current data, and common errors like concurrent modification. Missing explicit mention of permissions or rate limits, but overall transparent enough.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is lengthy but well-structured with sections: purpose, parameters, returns, examples, best practices, errors, related tools. Front-loaded with purpose. Some redundancy could be trimmed, but every section provides value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 5 parameters, nested objects, and no output schema, the description comprehensively covers prerequisites, effects, examples, error handling, and related tools. It ensures an agent can correctly invoke the tool without missing information.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, but the description adds crucial context: flow_id source, name max length, folder_id valid IDs and root usage, data structure details. This adds significant value beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states it modifies flow properties, configuration, or organization. It lists specific updatable aspects (metadata, structure, folder) and clearly distinguishes from siblings like create_flow, get_flow, and delete_flow.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Includes explicit 'Best Practices' (e.g., use get_flow before updating, partial updates, rebuild with build_flow) and 'Related Tools' section listing alternatives like get_flow, build_flow, and create_flow. Provides clear when-to-use guidance and error handling tips.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_folderB

nameNoNew folder name
folder_idYesFolder ID (UUID) to update
parent_idNoNew parent folder ID (UUID)
descriptionNoNew folder description

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, and the description only lists updatable fields without disclosing behavioral traits like required permissions, side effects, response structure, or error conditions. For a mutation tool, this is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is one short sentence, directly stating the action and scope. Efficient and front-loaded, though could benefit from more structured detail without being verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 4 parameters, no output schema, and no annotations, the description is too minimal. It omits return values, constraint details, and context about the updates' effects. Incomplete for a mutation operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for all parameters. The description summarizes the updatable fields but adds no additional meaning beyond the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clear action verb 'update' with resource 'folder', and explicitly states which attributes can be changed (name, description, parent). Distinguishes from sibling tools like create_folder, delete_folder, list_folders.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implied usage for updating folders, but no explicit guidance on when to use vs alternatives, no exclusion criteria, and no mention of prerequisites or side effects.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_mcp_project_configB

Update the MCP configuration (settings and auth settings) for a project.

ParametersJSON Schema

settingsYesPer-flow MCP settings
project_idYesProject ID (UUID)
auth_settingsNoOptional auth settings

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must fully convey behavioral traits. It merely states the update action without disclosing side effects (e.g., whether it overwrites or merges), auth requirements, rate limits, or consequences of missing or invalid parameters. This is insufficient for safe agent invocation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that is concise and front-loaded. However, it sacrifices detail for brevity; additional information could be included without harming conciseness. Still, no waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is minimal: it does not explain the return value (likely success/failure), permissions needed, or any constraints. Given the absence of an output schema and annotations, the description should provide more context for a mutation tool of this complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 100%, so the schema already documents all parameters. The description adds no additional meaning beyond mentioning 'settings and auth settings', which are already covered. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the verb 'Update' and the resource 'MCP configuration', specifying the parts being updated ('settings and auth settings'). This clearly distinguishes it from sibling tools like get_mcp_project_config (read) and install_mcp_project (install).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. There are no prerequisites, conditions, or exclusions mentioned, leaving the agent to infer usage context from the tool's name and schema alone.

Update an existing MCP server configuration by name.

ParametersJSON Schema
NameRequiredDescriptionDefault
configYesMCP server config
server_nameYesMCP server name

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It indicates a mutation ('update') but does not disclose whether it overwrites or merges the config, triggers a restart, requires specific permissions, or returns a success/failure response. This lack of detail is insufficient for an agent to anticipate side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no redundant information. It achieves conciseness while conveying the core purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple update tool with two parameters (one nested) and no output schema, the description is minimally adequate but missing critical context: it does not explain the return value, behavior when server_name doesn't exist, or whether the config is merged or replaced. The nested config object adds complexity that the description does not address.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the parameter descriptions in the schema are comprehensive. The description adds no additional semantic meaning beyond what the schema already provides (server_name and config with nested fields). Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Update', the resource 'MCP server configuration', and the method 'by name'. It effectively distinguishes the tool from siblings like create_mcp_server (for new servers), get_mcp_server (for retrieval), and delete_mcp_server (for removal).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites (e.g., the server must exist). The context of sibling tools implies its purpose, but no explicit when/when-not criteria are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_memory_baseB

Update an existing memory base by ID.

memory_base_idYesMemory base ID

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It only states 'Update an existing memory base by ID' without disclosing permission requirements, mutation details (e.g., partial vs full update), error behavior, or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence of 6 words, front-loaded with the key action and resource. No unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the 4-parameter complexity, lack of output schema, and no annotations, the description is insufficient. It does not explain update semantics (partial vs full), success indicators, or error conditions, leaving the agent unsure of tool behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with clear descriptions for each parameter. The tool description adds no additional semantic value beyond the schema, so baseline 3 is appropriate.

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavior. It states 'update' but does not specify partial update behavior, side effects, authorization needs, or what happens if fields are omitted. Schema implies optional fields but description adds no clarity beyond that.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, 14 words, front-loaded with action. Every word earns its place; no redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 7 parameters, no output schema, and proximity to many related monitor tools, the description is too minimal. It does not explain what a 'monitor message' is, its relationship to other monitor entities, or the return value. The agent lacks context for proper invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% (all 7 parameters have descriptions), so baseline is 3. The description lists some fields but does not add meaning beyond the schema. It omits noting 'sender_name' as an updatable field, but schema covers it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the verb 'Update' and resource 'monitor message', listing updatable fields. Differentiates from sibling tools like get_monitor_message (read) and delete_monitor_messages (delete). Could be more specific about the system context (e.g., monitoring system).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives, no prerequisites or exclusions. The description implies usage by listing fields but does not explicitly state when to choose this over other monitor tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Simple tool with few parameters and no output schema. Description covers basic purpose but lacks usage context, return value expectations, or error handling. Adequate but not thorough.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents all parameters. The description adds minimal value by summarizing that name and description are changeable, but does not explain any constraints (e.g., required project_id, uniqueness of name). Meets baseline for high coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Update an existing project') and the specific fields that can be changed ('name or description'). This distinguishes it from sibling tools like create_project, delete_project, and get_project.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. Lacks prerequisites or conditions (e.g., the project must exist). Does not mention any limitations or when not to use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_shared_messageC

Update a shared (playground) message for a source flow.

ParametersJSON Schema
NameRequiredDescriptionDefault
textNoUpdated message text
filesNoUpdated file references
senderNoUpdated sender
message_idYesMessage ID

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden but only states 'Update' without revealing consequences such as whether the original message is overwritten, any required permissions, or side effects. The brief description lacks behavioral detail.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence, no fluff. However, it is slightly under-specified given the tool's complexity; a bit more detail could be added without sacrificing conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For an 8-parameter mutation tool with no output schema and no annotations, the description is too sparse. It doesn't cover return values, side effects, or the update semantics, leaving the agent with insufficient context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds minimal value beyond the schema, only implying the source flow context. It doesn't explain relationships between parameters or usage constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it updates a shared (playground) message for a source flow, distinguishing it from other update tools like update_monitor_message. However, it could more explicitly differentiate from siblings like get_shared_messages.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs. alternatives (e.g., get_shared_messages, delete_shared_session). No prerequisites or context for appropriate usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_userB

ParametersJSON Schema
NameRequiredDescriptionDefault
user_idYesUser ID (UUID) to update
passwordNoNew password
usernameNoNew username
profile_imageNoNew profile image URL or path

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Discloses mutation and return of updated object, but lacks details on authentication, partial updates, side effects, or error cases. Does not mention if updates are immediate or require confirmation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no redundant words. Front-loads the core purpose and quickly adds key details (updateable fields, return value). Efficient and scannable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, but description mentions return of updated user object without detailing structure. Does not address what happens if user_id is invalid or missing permissions. Given the complexity (4 params, 1 required), more context is needed for safe usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for all 4 parameters. Description adds minimal value beyond listing the updatable fields, but does not explain constraints (e.g., password format, uniqueness of username, image URL validation). Baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states verb 'update', resource 'user profile information', and lists specific modifiable fields (username, password, profile image). It distinguishes from siblings like create_user and reset_user_password by focusing on profile updates.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., reset_user_password for password-only changes, or other update tools). No context on prerequisites or scenarios where this tool is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

variable_idYesVariable ID (UUID) to update

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It only restates the fields that can be changed, without disclosing side effects, return values, validation, or authorization requirements. This is minimal added information beyond the schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short sentence that efficiently conveys the core purpose without redundancy. Every word is meaningful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity of the tool (4 parameters, no output schema), the description is minimally adequate. However, it omits key details such as return behavior, whether omitted fields remain unchanged, and potential validation rules.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds little semantic value beyond summarizing which fields can be updated; it does not explain constraints like type compatibility or partial update behavior.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'update' and the resource 'variable', and lists the changeable fields (name, value, type). It effectively distinguishes from sibling tools like create_variable and delete_variable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

ParametersJSON Schema
NameRequiredDescriptionDefault
flow_idYesFlow ID (UUID) to upload file to
file_nameYesName of the file to upload
file_contentYesBase64 encoded file content

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. Description claims 'Supports multipart/form-data' but input schema expects Base64 string, creating contradiction. Missing details on authorization, file size limits, or overwrite behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no fluff. Could be slightly improved by removing the redundant format mention, but overall concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema; description does not state what the response contains (e.g., file ID). Lacks context on success behavior or error conditions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so description adds no new meaning beyond parameter names and descriptions. Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states uploading a file to a specific flow. The verb 'upload' and resource 'file' are specific. However, it does not differentiate from similar siblings like upload_file_v2 or upload_flow.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

ParametersJSON Schema
NameRequiredDescriptionDefault
appendNoAppend to an existing file
ephemeralNoMark the file as ephemeral
file_nameYesName of the file to upload
file_contentYesBase64 encoded file content

TDQS

B3.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of disclosing behavioral traits. It fails to mention important details such as whether the file is overwritten or appended on conflict, size limits, authentication requirements, or any side effects. For a mutation tool, this is insufficient transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: two sentences that front-load the core action and parameters. Every word is necessary and informative. There is no fluff or repetition, making it easy for an AI agent to quickly understand the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 4 parameters, no annotations, and no output schema, the description is too minimal. It does not clarify what the return value looks like, potential error conditions, or any constraints like file size limits. A user-scoped file upload tool should provide more context about the operation's implications.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema covers 100% of parameters with descriptions, so the baseline is 3. The description reiterates the key parameters (base64 file content, filename) and mentions optional flags (append, ephemeral) but does not add meaningful semantic information beyond what the schema already provides. It meets the minimum bar but does not enhance understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the action (upload), resource (user-scoped file), and the specific API endpoint (/api/v2/files). It also distinguishes from other upload tools (e.g., upload_file, upload_project) by specifying 'user-scoped', which implies per-user files. This leaves no ambiguity about what the tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool is for user-scoped files, which provides some context compared to other upload tools, but it does not explicitly state when to use this tool versus alternatives (e.g., upload_file v1), nor does it mention any preconditions or when not to use it. The guidance is implicit and minimal.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

upload_flowB

Upload a flow from file data. Provide an object with name, content (stringified JSON), and optional type fields.

ParametersJSON Schema
NameRequiredDescriptionDefault
fileYesFile object with fields: name (string), content (string, max 10MB), type (optional string)

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not mention side effects, permissions, size limits (beyond schema), or what happens after upload. The schema notes a 10MB limit, but the description omits this.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no redundancy. The first sentence front-loads the action, and the second details the input. Every word serves a purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the absence of an output schema and the complexity of nested parameters, the description is minimally adequate. It explains the input but lacks behavioral details and does not specify what the tool returns.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the description paraphrases the schema without adding new meaning. It clarifies the nested structure but doesn't provide additional semantic value beyond the schema.

Upload folder from compressed archive. Provide base64-encoded file content and filename. Creates folder structure and imports all flows.

ParametersJSON Schema
NameRequiredDescriptionDefault
file_nameYesArchive filename
file_contentYesBase64-encoded archive file content

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description must fully disclose behavioral traits. It states that it creates folder structure and imports flows, but lacks details on side effects (e.g., overwrite behavior, conflict resolution, required permissions, supported archive formats, and error handling). For a mutation tool, this is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity of the tool (one parameter, no output schema), the description is mostly adequate. However, it lacks information about error behavior, return format, and whether it requires any special permissions. It is not fully complete for an agent to understand all implications.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% (the parameter 'prompt' is described as 'Prompt template to validate'). The description adds that it checks variable syntax and returns extracted variables, providing context beyond the schema. However, this is not highly detailed, so a score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'validate' and the resource 'prompt template syntax'. The second sentence specifies that it checks variable syntax and returns extracted variables. However, it does not distinguish itself from siblings; there is no mention of when to use this over other tools like validate_code.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. The description implies usage for validation but lacks explicit context, such as prerequisites or scenarios where this tool is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

C2.9/5.0
Disambiguation2/5

Many tools have overlapping purposes, especially execution (run_flow, run_flow_advanced, run_flow_session, run_workflow) and file handling (upload_file, upload_file_v2). The high count and similar descriptions make it difficult for an agent to distinguish between them.

Naming Consistency3/5

Tool names follow snake_case with a mostly predictable verb_noun pattern (list_*, create_*, delete_*), but there are inconsistencies like 'agentic_assist' and 'health_check' and many '_v2' suffixes that break the pattern slightly.

Tool Count1/5

With 216 tools, the server is far too large for an MCP server. This extreme count overwhelms agents and includes many deprecated or rarely used endpoints, making it difficult to navigate.

Completeness4/5

The tool surface covers nearly every aspect of the Langflow API (flows, folders, variables, knowledge bases, monitoring, auth, etc.), leaving few obvious gaps. However, the inclusion of deprecated endpoints and multiple variants (e.g., run_flow vs run_workflow) adds unnecessary redundancy.
