reverb_shop_feedback

Fetch paginated individual buyer feedback for a Reverb shop by slug, returning each rating, message, and order reference for detailed reputation review.

Instructions

Get a Reverb shop's buyer feedback. Returns a page of a Reverb shop's individual buyer feedback entries (rating, message, and the order each review was left for) -- reputation detail reverb-shop does not carry (reverb-shop only exposes the aggregate feedback_count/rating_percentage). slug is the shop's slug, from a listing's own shop link or reverb.com/shop/{slug}. An unknown slug returns a typed not-found error.

A4.5/5.0
Behavior4/5

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

With no annotations, the description carries the burden and does reasonably well: it discloses the returned fields (rating, message, order), that results are paginated, and that an unknown slug produces a typed not-found error. It omits auth/permission or rate-limit behavior, keeping it short of a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three front-loaded sentences, each earning its place: purpose, returned fields plus sibling contrast, then slug sourcing and error behavior. No filler or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema or annotations, yet the description covers return contents, pagination, error behavior, and the input's provenance, so an agent has everything needed to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3, but the description adds real meaning by telling the agent where the slug comes from (a listing's own shop link or reverb.com/shop/{slug}) and by describing the page parameter's paging behavior. That is useful semantics beyond the bare schema text.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Get) and resource (a Reverb shop's buyer feedback), and explicitly distinguishes it from the sibling reverb_shop by noting that reverb_shop only carries the aggregate feedback_count/rating_percentage. An agent can tell exactly what this returns without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The contrast with reverb_shop ('reputation detail reverb-shop does not carry') gives clear context for when to pick this tool over the aggregate sibling. It lacks explicit when-not-to-use guidance or prerequisites, but the sibling routing is well handled.

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