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

No annotations are provided, so the description carries the full transparency burden. It does disclose that a prior search is required (search_id/hotel_slug) and that each room has an opcao_id for later steps. However, it does not explicitly state whether it is read-only, potential errors, or any side effects.

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 two sentences: the first front-loads the main purpose and prerequisites, the second succinctly explains the output's use. Every word contributes, with no filler or redundancy.

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?

Given there is no output schema, the description adequately hints at the return data by mentioning opcao_id and its role in subsequent tools. The tool has only 3 parameters and a simple list operation, so the description covers the critical workflow context for correct invocation.

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?

With 0% schema description coverage, the description compensates by explaining the meaning and source of search_id and hotel_slug (returned by search_hotels). Token is not clarified, but it is a common auth parameter. This adds meaningful semantic value for two of the three parameters.

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 clearly states the verb 'Lista' (lists) and the resource 'apartamentos/tipos de quarto' for a single hotel within an existing search. It distinguishes itself from siblings like search_hotels and list_hotels by specifying it operates on a previous search and returns room options.

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?

The description explicitly says to use the search_id and hotel_slug returned by search_hotels, and directs the resulting opcao_id to get_quote and create_payment. This provides clear when-to-use context and workflow sequencing, though it doesn't explicitly state when not to use it or name alternatives.

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