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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description goes beyond that by disclosing the visibility filter (private ratings excluded) and result ordering ('newest first'), which are genuine behavioral traits an agent cannot get from annotations. It stops short of describing pagination behavior for the limit parameter.

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 front-loaded sentence with zero filler; the scope constraint and ordering both earn their place, and nothing is repeated from structured fields.

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 read-only list tool with no output schema and one optional param, the description covers what is returned (public client reviews) and how it's ordered. The only gap is the undocumented limit/pagination semantics, which is a minor omission otherwise.

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 single parameter (limit) has 0% schema description coverage — the schema only supplies min 1 / max 100 bounds. The description never mentions the limit or its default, so an agent gets no semantic guidance on controlling result size. This is the weakest area for a one-parameter tool with no schema documentation.

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 resource (the coach's own client ratings/reviews) with clear implicit verb (retrieve/list) and scope (own, public only). An agent can infer this returns individual reviews rather than aggregate stats, distinguishing it in spirit from get_my_rating_summary, though the sibling is never named.

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 is implied by 'the coach's own' — you call it to read your own reviews — and the 'public ones only' clause hints at what will and won't appear. However, no alternative is named (get_my_rating_summary exists as an obvious sibling) and there is no when-not guidance.

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