olist_expedicao_pesquisar_agrupamentos

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

The description provides no behavioral details beyond the fact that it is a search operation. It does not state whether it is read-only, any pagination behavior, or response format. Since there are no annotations, the description carries the full burden and fails to disclose important traits.

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 concise, consisting of three short fragments, but it is somewhat sparse. It front-loads the core purpose, then adds endpoint and documentation, which is acceptable but not particularly structured.

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 has no annotations and no output schema, and the description does not explain return values, filtering semantics, or relationship to other expedition tools. The documentation link may help, but within the description context, it is incomplete for an agent to understand full capabilities.

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?

All five parameters are documented in the input schema with descriptions, so baseline is 3. The description itself adds no parameter-level context beyond what the schema already provides.

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 that this tool searches 'agrupamentos' (groupings) via the API V2 endpoint, giving a specific verb and resource. It does not explicitly differentiate it from sibling tools like olist_expedicao_pesquisa or olist_expedicao_obter, but the resource 'agrupamentos' is specific.

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 such as olist_expedicao_pesquisa or olist_expedicao_obter. The only additional information is a documentation link, which is not in-line guidance.

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