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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds real context beyond that with 'Free and public' (no cost, no authentication concern) and by disclosing the shape of the returned record.

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?

A single dense sentence with the resource and the returned fields front-loaded and zero filler. It is a sentence fragment rather than a full statement of action, which slightly blurs the leading edge.

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?

With no output schema, the description carries the return-value burden and does so by listing the fields an agent gets back. Only gaps are the semantics of the id argument and behavior when the id does not match a request.

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% and the single uuid 'id' parameter is undocumented in both schema and description. The phrase 'One request on the Requests board' only implicitly frames the id as a request identifier, so the description does little to compensate, though a lone id for a named-resource getter is largely self-evident.

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?

States a specific verb+resource (read one request) and enumerates what comes back: its answers, the linked unit or dataset version, the note, the chosen answer, and purchase status. It clearly contrasts with the sibling list_requests ('One request') but never names that alternative.

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?

'One request on the Requests board' implies you call this when you already have a single request id, and 'Free and public' hints there is no cost or auth barrier. There is no explicit when-to-use/when-not guidance and no sibling is named as the alternative for listing.

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