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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Detalhar categoria', which does not state whether this is a read-only operation, what happens if the category is not found, or any error behavior. The existence of an output schema helps, but the description adds no insight into side effects or authorization.

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 extremely concise ('Detalhar categoria' – two words), which is front-loaded and efficient. However, it borders on under-specification, lacking any additional structure or explanatory content. For a simple get-by-id tool, this is acceptable but not exemplary.

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 the tool's simplicity (1 param, output schema exists), the description is minimal but lacks important context. It does not explain parameter semantics, usage scenarios, or why this tool exists alongside similar ones. The output schema might provide return structure, but the description itself is incomplete for confident agent selection.

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 description coverage is 0%, and the description does not compensate. The sole parameter 'id' is an integer with no schema description, and the description does not explain what it refers to. The agent is left to infer that 'id' is the category identifier, but no value is added beyond the schema field name.

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 'Detalhar categoria' (Portuguese for 'Detail category') clearly indicates a retrieve-by-ID operation for a single category. It distinguishes from the sibling 'getCategories' (plural) because of the singular focus and required 'id' parameter. A specific verb and resource are present, though it could more explicitly state 'by ID'.

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 usage guidance is provided. The description does not mention when to use this tool versus alternatives like 'getCategories' or 'getCategory' (if multiple). There are no exclusions, prerequisites, or contextual hints for when this endpoint is appropriate.

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