사용 예

코드에 대한 설명이 필요하다고 가정해 보겠습니다. 에이전트에게 응답을 평가하고 Root Signals 평가기를 사용하여 개선하도록 지시하기만 하면 됩니다.

일반 LLM 답변 후 에이전트는 자동으로

  • Root Signals MCP(이 경우 Conciseness 과 Relevance )를 통해 적절한 평가자를 발견합니다.

  • 그들을 실행하고

  • 평가자의 피드백을 바탕으로 더 높은 품질의 설명을 제공합니다.

그런 다음 두 번째 시도를 자동으로 다시 평가하여 개선된 설명이 실제로 더 높은 품질인지 확인할 수 있습니다.

Available Tools

3 tools
execute_pythonB

Execute Python code and return the output. Variables persist between executions.

ParametersJSON Schema
NameRequiredDescriptionDefault
codeYesPython code to execute
resetNoReset the Python session (clear all variables)

TDQS

B3.4/5.0
Behavior2/5

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

With no annotations provided, the description must disclose behavioral traits on its own. It does state that variables persist between executions, which is a key stateful behavior. However, it omits other critical aspects such as error handling, output format, sandboxing, timeouts, or potential side effects, making the behavior of arbitrary code execution largely opaque.

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 long, with the main action 'Execute Python code' front-loaded. Every word serves a purpose, and there is no redundant or tangential information.

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 tool that executes arbitrary code, this description is underspecified. It does not explain what 'output' includes (stdout, stderr, exceptions), nor does it address side effects, resource limits, or session behavior beyond persistence. Since there is no output schema, the description should have elaborated further, but it leaves 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 description coverage is 100%, so both parameters (code and reset) are fully described in the schema. The description adds no additional parameter semantics, but per the rubric, the high schema coverage warrants a 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 identifies the tool's function: executing Python code and returning output. This specific verb+resource combination distinguishes it from sibling tools like list_variables and install_package, 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 Guidelines3/5

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

The description implies usage when one needs to run Python code, but it provides no explicit guidance on when to use this tool vs. alternatives. It does not mention list_variables or install_package or any exclusion conditions, leaving the usage context somewhat implicit.

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

install_packageB

Install a Python package using uv

ParametersJSON Schema
NameRequiredDescriptionDefault
packageYesPackage name to install (e.g., 'pandas')

TDQS

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 the full burden of behavioral disclosure, but it only says 'Install a Python package using uv'. It does not mention side effects such as modifying the environment, requiring network access, or how conflicts are resolved. The mention of 'uv' adds a detail about the package manager but lacks consequential 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, front-loaded sentence that immediately communicates the tool's purpose. It contains no unnecessary words or fluff, making it highly concise 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?

For a simple one-parameter tool, the description provides the core action and method, but it lacks usage guidelines and behavioral transparency. Given the absence of annotations, the description is not fully complete, though it covers the basics for a basic install 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 input schema already fully describes the single parameter with 100% coverage, including an example ('pandas'). The description adds no additional semantic value beyond the schema, so the 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 specific action ('Install') the resource ('a Python package') and the method ('using uv'). It distinguishes itself from sibling tools like execute_python and list_variables by indicating a package installation operation rather than code execution or variable inspection.

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 mention situations such as needing to add a dependency, nor does it exclude using execute_python or list_variables for other tasks. The absence of any usage context or alternative comparisons leaves the agent without clear decision-making support.

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 variables in the current session

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 convey behavioral traits. It implies a read-only listing but does not state whether values are included, how the result is returned, or if there are side effects. 'Current session' is ambiguous and not elaborated.

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, direct sentence with no wasted words. It is front-loaded and appropriately sized for a zero-parameter tool.

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 and no annotations, so the description should explain what the output looks like. It only says 'list all variables', leaving unclear whether the output is names only or names with values, and what format is used. For a simple tool this might be sufficient, but it lacks 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 zero parameters, so the schema is trivially complete. The description does not need to explain parameter details; the baseline of 4 applies because there is nothing to clarify.

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 'List' and a clear resource 'variables', scoped to 'current session'. It obviously differs from sibling tools like execute_python and install_package, so purpose is 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 about when to use this tool versus alternatives. There is no mention of prerequisites, exclusions, or comparison with execute_python or install_package. The description only states the action, not the context of use.

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

TDQS

A3.8/5.0
Disambiguation5/5

Each tool has a clear, non-overlapping purpose: execute_python runs code, list_variables inspects session state, and install_package manages dependencies. There is no ambiguity in what each tool does.

Naming Consistency5/5

All tool names follow the same verb_noun pattern with snake_case: execute_python, list_variables, install_package. The naming is perfectly consistent and predictable.

Tool Count5/5

With only 3 tools, the server is tightly scoped to its purpose of providing a persistent Python execution environment. Each tool is essential and the count is well within the ideal range.

Completeness4/5

The server covers the core workflow of executing Python code, inspecting session variables, and installing packages. A minor gap is the lack of explicit session reset or variable removal, but these are not critical for typical usage.
