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

Annotations already declare readOnlyHint=true, but the description adds real behavioral context beyond them: a hard 100-per-call cap, the Beta status of the endpoint, and the underlying Beds24 API path. It does not say whether more than 100 reviews exist or how to page past the cap, so it stops short of 5.

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 compact sentences, front-loaded with the resource and content, followed by the cap and the Beta/endpoint metadata. No filler or repetition of the title.

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, single-parameter tool with no output schema, the description covers the return contents, the row cap and the Beta caveat, which is close to sufficient. It leaves open how to retrieve reviews beyond the 100 cap or whether results are ordered by date, a minor gap for a one-parameter list endpoint.

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% and the single roomId parameter is fully documented in the schema (Beds24 room id linked to the Airbnb listing). The description adds only the phrase 'for one room', so it neither compensates for nor extends the schema meaningfully — baseline 3.

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 verb (List) and resource (Airbnb guest reviews for one room), then enumerates the returned content types (ratings, public review, private feedback, host response), which cleanly distinguishes it from the sibling beds24_list_booking_com_reviews.

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 only implied: the agent can infer you call it with a roomId to fetch that room's Airbnb reviews. There is no explicit statement of when to prefer it over the Booking.com counterpart or which room states produce results, leaving selection to inference.

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