list_fastapi_pages

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

Annotations already declare readOnlyHint=true and openWorldHint=true, meaning the tool is a safe read with potentially dynamic results. The description adds no further behavioral context, which is acceptable given the annotations provide adequate transparency.

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

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

The description is a single, clear sentence with no redundant words. It is appropriately front-loaded and efficient.

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

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 annotations covering safety and openness, the description suffices. It could optionally hint at the output format (e.g., 'returns a list of sections'), but the current text is minimally adequate.

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

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

The input schema has zero parameters, and the description does not mention any. Since there are no parameters, the description does not need to add meaning beyond the schema. Score baseline 4.

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

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

The description 'List all available FastAPI doc pages, categorized by section' uses a specific verb ('list') and resource ('FastAPI doc pages'), clearly distinguishing it from sibling tools like 'get_fastapi_docs' which retrieve specific pages or 'search_fastapi_docs' which search.

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

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

No explicit when-to-use or when-not-to-use instructions. However, the description implies it is for browsing available pages, and sibling tool names suggest different purposes (e.g., 'compare_fastapi_approaches' for comparison). Implicit differentiation but no exclusions.

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