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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety/scope profile is covered. The description adds that only highlighted reviews (a curated subset, not the full review corpus) plus an overall rating are returned – useful, but no mention of pagination, locale effects, or data freshness.

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?

A single efficient sentence with the resource and payload front-loaded. Nothing wasted, though it is arguably too terse for the parameter surface it covers.

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?

An output schema exists so return values need not be described, but six parameters sit at zero documentation in both schema and description, and there is no usage context. For a reviews endpoint tied to a specific property, that leaves the agent guessing how to call it.

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 0% across six parameters (property_id, check_in, check_out, adults, locale, currency), and the description explains none of them. With half a dozen undocumented params, the description should have clarified at least property_id and the date/adult context needed for review relevance.

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 clear resource (Expedia Stays property) and the two things returned: overall rating and highlighted guest reviews. It implicitly distinguishes itself from expedia_properties_detail and expedia_properties_search by being the reviews-focused endpoint, though it never names those siblings.

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?

No when-to-use guidance, no mention of alternatives, and no indication of the precondition that a property_id must already be known (e.g., from expedia_properties_search). The agent gets no routing help.

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