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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered elsewhere. The description adds no behavioral context of its own: nothing about localization (despite a language parameter), no indication of whether the response is one blob or per-topic sections, and no note on link handling for 'links' texts. It is effectively a restatement of scope only.

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?

One short sentence with zero filler and the content list front-loaded. It loses a point because the fragment style (a comma-separated topic dump) has no main clause to anchor what the agent is being told.

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 tool is simple (one optional param, no output schema), so the description does not need to explain return values in detail. However, with no output schema at all, the description should at least hint at the shape of the policy response and the fact that output language follows the language argument – neither is present.

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?

There is a single optional parameter with 100% schema description coverage, so the schema already explains 'language' and its enum and default. The description adds nothing about the parameter, and notably never signals that results are localized, so the baseline 3 for high coverage is the right ceiling rather than a 4.

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 enumerated topic list (check-in/out, cancellation, payment, pets, house rules, guest registration, extras, contact, FAQ) makes the resource returned unmistakable and clearly separable from the sibling tools, none of which cover policy content. It stops short of a 5 because the description is a bare noun fragment with no verb and no statement of what the tool actually returns (text? links? structured fields?).

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?

Usage is implied by the topic enumeration – an agent can infer it should call this for check-in or pet questions – but there is no explicit when-to-use framing, no mention of the alternative tools (get_apartment_details, get_quote) and no exclusions. For a purely informational lookup this is adequate but leaves routing to inference.

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