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 covered. The description adds real value beyond them by describing the exact status vocabulary and the presence of a team response, which an agent cannot get from the annotations or an empty schema.

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?

The first sentence is front-loaded and information-dense, but the trailing 'Free; needs a key. Needs an API key or a connected account.' says the same auth requirement twice in two different phrasings. Halving that tail would lose nothing.

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 zero-parameter, read-only lookup with no output schema, the description supplies the salient return semantics (status values, hidden reason, team response) and the auth prerequisite. The only gap is that the tool does not say what happens when no review exists, which 'if you posted one' only gestures at.

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 tool takes zero parameters, which is the baseline-4 case, and the description correctly signals this is a self-scoped lookup requiring no input identifiers. Nothing further is needed or expected here.

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 names a specific verb ('get') and resource ('your review of the product') and enumerates the returned content: status (published, pending, hidden with reason) and the team's response. That distinguishes it from list_reviews and list_my_feedback, though the phrase 'the product' is never defined and there is no explicit sibling callout.

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?

The conditional 'if you posted one' implies when this tool is applicable, but there is no explicit routing to list_reviews or list_my_feedback for the cases where the agent wants all reviews or a broader feedback list. Usage is inferable rather than stated.

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