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

Annotations already establish readOnly/idempotent/non-destructive behavior; the description adds the HTTP GET method and the important bulk execution trait. It does not describe errors or response shape, but this is acceptable for a simple read tool with these annotations.

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?

Two short sentences, front-loaded with the main purpose and followed by a useful bulk note. There is no filler or repetition of annotations.

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 read-only get-by-id tool with strong annotations, the endpoint and batch behavior are sufficient context. It is slightly incomplete in not addressing the account parameter or return values, but complexity is low.

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 helps by tying 'id' to the path parameter and explaining 'ids' for batched execution. However, 'account' is left completely unexplained, so it only partially compensates for the schema's lack of parameter documentation.

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?

Description uses a specific verb ('Detalha') targeting a question resource by id and gives the exact endpoint GET /questions/{id}. This clearly distinguishes it from siblings like mercadolivre_list_questions and other get_* tools.

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 bulk support note gives practical guidance for passing multiple ids, and 'por id' implies use when you have a question identifier. However, it never explicitly contrasts with list_questions or states when the batch variant should be preferred.

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