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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds nothing beyond that: no note on pagination behavior, result ordering, or whether a host ID must be valid, despite a required page parameter implying paginated results.

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?

It is short, but this is under-specification rather than conciseness: a three-word fragment carries no actionable information and nothing is front-loaded because nothing is said.

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?

The output schema and annotations reduce the burden, but the description still fails to state what a 'listing' result represents, how many are returned, or how pagination terminates. For a tool whose only distinguishing signal is its name, this leaves the agent guessing relative to several Airbnb siblings.

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% – both id (host/user ID with example) and page (1-based, default 1) are documented in the schema. The description adds no meaning beyond that, so the baseline 3 for fully documented schemas 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?

The description 'Airbnb host listings' merely restates the tool name and does not supply a verb or clarify the operation (fetch? list?). It implies the resource is listings associated with a host, but gives no detail about scope or pagination, and does not distinguish itself from siblings like airbnb_host, airbnb_host_reviews, or airbnb_room.

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 when-to-use guidance, no prerequisites, and no mention of alternatives. An agent must infer that this is the tool for enumerating a host's listings rather than their reviews (airbnb_host_reviews) or profile (airbnb_host).

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