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

Beyond the readOnlyHint/openWorldHint annotations, it discloses pagination behavior and a meaningful scope boundary ('Booking, account, and private review data are not included'). With an output schema and annotations already covering safety, this adds useful non-redundant context.

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?

Front-loaded and free of padding; each sentence carries material. The closing line about hotels_reviews is short but introduces ambiguity rather than clarity, keeping it just under top marks.

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?

With an output schema and full schema coverage, the description needn't explain returns, and it appropriately covers scope, pagination, and id provenance. The one genuine gap is that it never resolves how this tool differs from hotels_reviews.

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 coverage is 100%, so the schema documents every parameter. The description's property_id explanation (numeric global id from Search properties[].id) largely duplicates the schema text and adds little new syntax or format detail, so the default baseline applies.

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+resource ('Returns one page of public guest reviews for a Hotels.com property') and enumerates the returned fields. It names the sibling hotels_reviews, but the differentiation is muddled since both tools claim to return Hotels.com guest reviews, leaving the agent unsure why it would pick the archive variant.

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?

Gives real pagination guidance ('Use page and page_size to walk the archive; the response reports whether another page is available'), which is useful. However, the routing instruction 'Use hotels_reviews to get Hotels.com guest reviews' offers no condition that distinguishes the two tools, so when-to-use is only implied rather than stated.

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