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

The description adds the behavioral detail that results may be absent if reviews are not present in the fetched response, which is useful beyond the read-only annotation. However, it does not clarify whether this tool triggers a fresh fetch or relies on previously fetched data, nor does it describe pagination behavior despite a 'page' parameter.

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 with no fluff and is front-loaded with the key action.

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 detailed. The description is adequate but lacks sufficient context about when to use this tool and how it relates to siblings, which is important given the many Airbnb-related tools.

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 the schema already documents both parameters ('id' and 'page'). The description adds no additional parameter semantics, so the baseline of 3 is appropriate.

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 states it 'returns public Airbnb review snippets', which is a clear verb+resource, but the phrase 'when present in the fetched room response' is confusing and implies this might be a secondary or derived operation rather than a standalone tool. It is not explicitly differentiated from sibling tools like airbnb_room or airbnb_host_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?

There is no guidance on when to use this tool versus alternatives like airbnb_room (which might already include reviews) or airbnb_host_reviews. The user is left to infer usage context.

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