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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety bar is met without the description. The description goes beyond them by disclosing access-control behavior (no key needed for public items; private items restricted to reporter and team) and by describing what the response contains, including marked official team responses and a status timeline.

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?

Two tight sentences: the first front-loads what is returned, the second carries the access rule. No filler, no repetition of the title or annotations.

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 correctly takes on the job of describing the payload (status, upvotes, comments, timeline) and the auth model. It is nearly complete for a single-parameter read tool; only error/not-found behavior for a bad or inaccessible id is left unstated.

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 100% and there is only one parameter, whose schema description already explains that the id originates from list_feedback, request_feature or report_issue and gives an example. The description adds nothing further about the id, so the baseline of 3 applies.

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 opens with a specific resource and enumerates what the single item carries (status, upvotes, comments with official team responses marked, status-change timeline). 'One feedback item' implicitly contrasts with list_feedback, though it never names that sibling explicitly, so an agent must infer the singular-vs-list split.

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?

Usage context is implied by the retrieval framing and the schema note that the id comes from list_feedback/request_feature/report_issue, but the description itself never states when to fetch a single item instead of calling list_feedback or get_my_review. It does add a useful access condition (public items free, private issues visible to reporter and team) that shapes whether the call will succeed.

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