get_hotel_reviews

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and idempotentHint=true, signaling a safe, non-mutating operation. The description adds value by specifying the content: verified traveler reviews, category ratings, and comments, which is beyond the annotations. However, it does not disclose pagination behavior or that results vary by provider, leaving some behavioral aspects unexplained.

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 description is a single, concise sentence that front-loads the primary action and resource. It has no fluff or redundant wording. While it could mention provider handling or pagination, the structure is efficient and appropriate for a simple fetch tool, though not maximally informative.

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?

Given the presence of an output schema and strong annotations, the description covers the core function adequately. However, it does not address potential confusion with the sibling 'get_place_reviews' or mention that results are provider-specific. Pagination is implied by schema parameters but not surfaced in the description. For a straightforward fetch tool, this is minimally complete but leaves some contextual gaps.

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 all four parameters are already documented with types, defaults, and purpose. The description adds no additional parameter-specific semantics; it merely highlights what the tool returns. The baseline of 3 applies because the schema carries the full parameter burden and the description does not need to compensate.

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 clearly states the verb 'Fetch' and the specific resource 'verified traveler reviews' with added detail on category ratings and comments. It is specific and distinct from generic review fetchers, but does not explicitly differentiate from the sibling 'get_place_reviews', which could be a similar tool. The main purpose is clear, but sibling differentiation is omitted.

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 provides no guidance on when to use this tool versus alternatives. It does not mention that it targets hotel reviews specifically or when to prefer it over 'get_place_reviews'. There is no mention of provider specifics or conditions for use. The agent is left to infer usage from the name and schema.

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