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

Annotations already indicate it's not read-only (readOnlyHint=false), not idempotent, and not destructive. The description adds 'altera dados' (changes data), which is consistent but redundant. It fails to disclose important behavior such as validation constraints, required fields beyond id, or consequences of editing a fiscal document (e.g., issuance status).

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 short and front-loaded with the main purpose and REST method. The bulk support note is useful and concise. However, it repeats the tool name in the description, which adds little value, but overall it is compact and readable.

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 low complexity (no output schema, no nested objects) and annotations partially cover safety, the description is somewhat adequate but leaves gaps. It fails to explain the 'body' parameter structure, the meaning of 'account' (likely required for authentication), or any constraints on editing fiscal notas. Not fully complete but not drastically insufficient.

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 only mentions 'ids' for bulk support. Parameters like 'body', 'account', and 'id' are not explained in the description. However, the schema shows required 'id' and a 'body' string (likely JSON payload), but the description does not clarify expectations, leaving the agent to infer. It provides minimal added value beyond the schema.

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 this is an edit operation for 'Notas Fiscais de Consumidores' via PUT, distinguishing it from create/get/list/delete siblings. It is specific about the verb and resource, though it doesn't detail which fields can be edited.

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?

It implies usage for editing an existing nota fiscal, but there is no explicit guidance on when to use this vs alternatives (e.g., create for new records). The bulk note hints at multiple IDs, but no prerequisites or exclusion criteria are given.

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