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

The description adds '[write, altera dados]' which confirms the mutation behavior, aligning with readOnlyHint=false. It also notes bulk support. However, it does not disclose specific side effects, permissions, or edge cases beyond what annotations already suggest.

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, using two short sentences to convey the operation, endpoint, and bulk capability. There is no fluff or redundant content, and the most critical information is front-loaded.

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 description provides the core purpose and bulk support but omits parameter semantics and deeper behavioral context. With four parameters and no output schema, a bit more detail would help an agent invoke this tool correctly, though the basics are covered.

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?

Only the 'ids' parameter is partially explained with 'Bulk support: accepts ids for batched execution.' The required 'id' parameter, 'body', and 'account' are unexplained, and schema descriptions are entirely absent (0% coverage). The description fails to compensate for the lack of parameter details.

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 the operation 'Emitir' (Issue) for consumer fiscal notes and provides the exact HTTP endpoint, distinguishing it from sibling operations like create, cancel, and update. The resource and action are specific and unambiguous.

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 description implies usage by naming the operation and mentioning bulk support, but it does not explicitly state when to use this tool over alternatives like cancelar or create. There is no 'when-not' guidance or reference to sibling tools.

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