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

No annotations provided. Description adds billing info (3 requests per call) and speed caveat. However, does not disclose auth needs, limit, error behavior, or side effects. The billing note adds some value but leaves major gaps.

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?

Very short and to the point, but at the cost of clarity. Could include a one-sentence purpose. The billing and speed note are relevant but not enough to earn higher conciseness score.

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?

For a tool with 3 parameters and no output schema, the description is incomplete. It does not specify what is returned, how pagination works, or what the 'force' parameter actually does. The speed alternative hint helps but overall leaves agent guessing.

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 low (33%) with only 'force' having a schema description. The description does not explain any parameter meaning, e.g., 'amount' or relationship between 'username' and 'force'. No added value over schema.

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 does not explicitly state what the tool does. It starts with endpoint path and mentions a faster alternative, but purpose (retrieving user highlights by username) is only implied by the tool name and context. No verb or clear description of the resource.

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?

Provides one guideline: use by/id endpoint for speed. But lacks guidance on when to use this tool vs alternatives, prerequisites, or scenarios where it is appropriate.

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