vibekit_app_env
Read-onlyIdempotent

Get the environment variables configured for an app (names and values). Read-only — use vibekit_set_env to change them.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
appIdYesApp ID (from vibekit_list_apps)

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
okYesWhether the call succeeded.
dataNoThe app's environment variables as key-value pairs.
errorNoError message when ok is false (e.g. missing/invalid VIBEKIT_API_KEY, or an API error).

A4.5/5.0
Behavior4/5

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

Annotations already provide readOnlyHint=true and idempotentHint=true. The description reinforces the read-only behavior and adds context about returning 'names and values', which is useful beyond annotations.

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 zero wasted words. First sentence states the core action, second sentence provides usage guidance. Perfectly front-loaded.

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 read-only tool with a single parameter and an output schema, the description is fully adequate. It covers purpose, usage boundaries, and return content, leaving no 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% with the single parameter 'appId' already described as 'App ID (from vibekit_list_apps)'. The description does not add additional parameter context beyond the schema, 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?

Description starts with 'Get the environment variables configured for an app (names and values),' clearly stating the specific verb 'Get' and the resource 'environment variables for an app'. It directly distinguishes from sibling 'vibekit_set_env' by noting the read-only nature.

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 'Read-only — use vibekit_set_env to change them,' providing clear when-to-use and when-not-to-use guidance with a named alternative.

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

A4/5.0
Disambiguation4/5

Most tools have distinct purposes, but vibekit_chat and vibekit_submit_task both handle AI-driven code changes, leading to potential confusion. Descriptions help differentiate, but overlap exists.

Naming Consistency4/5

All tools use the 'vibekit_' prefix and lowercase with underscores. Most follow a verb_noun pattern, but a few (e.g., 'vibekit_account') are noun-only, causing minor inconsistency.

Tool Count3/5

36 tools is on the high side, covering many aspects of the platform. While mostly justified, the count feels slightly excessive and could be streamlined.

Completeness5/5

The tool set covers the full lifecycle of apps, databases, tasks, schedules, skills, QA, and environment variables. No obvious gaps for the stated domain.
