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

The annotations already declare read-only, idempotent, non-destructive, and non-open-world behavior. The description adds useful context about scope and return contents, including facts, sections, FAQ, and URL, but does not go much beyond that.

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 compact and front-loads the covered categories, with the list behavior and return contents placed afterward. The first sentence is dense and the phrase 'no other tool covers' is slightly awkward, but most content earns its place given the large topic enum.

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?

For a read-only content getter with an output schema, annotations, and fully described parameters, the description covers scope, list mode, and return shape adequately. The phrase 'the list' is slightly ambiguous about whether it means topics or something else, which keeps it from being fully complete.

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 already documents both parameters and the enum values. The description adds some meaning by grouping topics into categories and translating halbpension as half board, but otherwise largely repeats the enum and the schema note to omit topic for the list.

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 that this retrieves facts from a single hotel page and enumerates the covered categories: dining, wellness, services, activities, dates, arrival, history, and company stays. It distinguishes the tool from siblings with the claim that no other tool covers these topics, though the core action is implied rather than stated with a clean verb.

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?

It gives a clear operational rule: omit the topic parameter to get the list. The statement that no other tool covers these topics provides implicit routing guidance, but no sibling alternatives are named and there is no explicit when-not guidance.

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