grailed_seller_reviews

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose pagination ('Returns a page'), error behavior ('unknown username returns a typed not-found error'), and the content of the return payload. However, it omits some behavioral context such as page size, sorting, or whether rate limits apply, though these are not critical for invoking the call correctly.

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?

Three sentences, no filler. The action is front-loaded, the return content is listed compactly, the sibling contrast is concise, and the username sourcing plus error behavior are packed into the final sentence. Every clause earns its place.

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 two-parameter paginated listing tool with no output schema, the description provides the essential information: what it returns, how pagination works, where to get the input, and what happens on error. There is no output schema, so the enumerated return fields (rating, note, feedback tags, listing) are sufficient for an agent to understand what it will receive. Nothing needed for correct invocation is missing.

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 description coverage is 100%, so the baseline is 3. The description adds value beyond the schema by explaining where to source the username (from seller.username field or grailed.com/{username}) and implicitly clarifying the meaning of 'page' via the 'Returns a page' phrasing. This extra context lifts it to 4.

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 verb+resource pair: 'Get a Grailed seller's buyer feedback.' It details exactly what is returned (rating, note, feedback tags, listing) and explicitly differentiates itself from the sibling tool grailed_seller, which only carries aggregate rating_average/rating_count. This makes the tool's purpose unambiguous.

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 description explicitly names the alternative grailed-seller and states the precise differentiator: grailed_seller_reviews provides individual feedback entries that grailed-seller does not carry. It also tells the agent where to obtain the username (from listing's seller.username field or grailed.com/{username}), giving clear, actionable guidance on when and how to use the tool.

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