list_components

Lists all JSX components in a file, providing their locations, props, and children information to help developers navigate and understand component structure.

Instructions

TDQS

A3.8/5.0
Behavior3/5

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

With no annotations, the description carries the full burden. It describes the returned information (locations, props, children) but does not disclose side effects, error behavior, or explicitly state that it is read-only. For a simple listing tool, this is adequate but not rich.

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, front-loaded sentence that clearly states the tool's purpose and output. Every word earns its place with no extraneous 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 tool is simple (one parameter, no output schema) and the description sufficiently covers what the tool does and returns. However, without an output schema, adding a note about the return format or limitations (e.g., only parses valid TSX/JSX) 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 already fully documents the single parameter filePath with a clear description. The tool description does not add additional parameter semantics beyond what the schema provides, 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 tool 'List all JSX components in a file' with specific output details (locations, props, children info). This is a specific verb and resource, and it distinguishes from sibling tools like find_component_usages or analyze_file by focusing on component listing.

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 an overview of components in a file is needed, but does not explicitly mention when to use it over alternatives or any exclusions. No sibling tools are referenced, so guidance is limited to the natural reading of the purpose.

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