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

No annotations provided, so description must carry full burden. It only states it fetches docs, with no info on side effects, permissions, rate limits, or return behavior. 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.

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

Extremely concise, one sentence of 8 words. Structure is front-loaded, but lacks any parameter or usage details. For a tool with 3 params, it could be more structured.

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 3 params and no annotations, the description is incomplete. It fails to explain what 'ctx' or 'query' means, what 'library' does, or what the output contains. An existing output schema is not leveraged.

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?

Schema coverage is 0%; none of the three parameters (ctx, query, library) are described. The description adds no meaning beyond the raw schema, leaving agents to guess parameter roles.

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?

Description clearly states verb 'Fetch' and object 'documentation for a framework via Context7', indicating a documentation retrieval tool. However, it could be more specific about what kind of documentation (e.g., API, usage) and context7 is undefined.

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 guidance on when to use this tool vs siblings. The description does not mention any context, prerequisites, or alternatives, leaving the agent without direction on proper invocation.

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