GET /serviceCategory/:id (Service Category)

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

Annotations already declare readOnlyHint and destructiveHint. The description adds no new behavioral details (e.g., return format, authorization needs). With annotations present, the description is adequate but does not provide extra context.

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 a single, concise sentence in Portuguese. It is front-loaded with the core action, no wasted words. Could be slightly more descriptive but efficient.

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 simple retrieval tool with one parameter and annotations, the description is minimally complete. However, no information about what the returned data contains or if there are any constraints is given. Could be improved with a brief note on the scope of data returned.

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% and description does not add meaning beyond the schema. Parameter 'id' is fully defined in the schema, so baseline of 3 is appropriate.

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 'Recuperação dos dados de Categoria de Serviço' clearly indicates retrieval of service category data, distinguishing it from sibling 'list_service_categories' which would return multiple. It implies a single entity fetch, aided by the required id parameter.

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?

No explicit guidance on when to use this tool versus alternatives like 'list_service_categories'. Usage is implied by the parameter and name, but lacking explicit context for agents.

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