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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorld=true, so the safety profile is partly covered. The description adds real context beyond that: it operates only under the connected Gover account's permissions, it is a two-phase prepare step that does not execute, credentials must never be passed as arguments, and result overflow goes to gover_ler_resultado. Good disclosure, though the tension between 'prepares without executing' and destructiveHint=true is left unexplained.

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?

Purpose is front-loaded in the first sentence, then ordered directives for the prepare/confirm flow and result handling. Every sentence carries an instruction, but the sequence is a bit of a list rather than tightly grouped, keeping it just below top marks.

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 complex nested-parameter, non-idempotent, destructive two-phase tool, the description covers the workflow, credential safety and result handling well. However, it gives no information about what any of the 8 parameters or the nested formData fields mean, and there is no output schema, so an agent still lacks the field-level knowledge needed to populate the call correctly.

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% across 8 top-level parameters and a nested formData object with many fields, so the schema provides no semantic help. The description's only parameter guidance is 'Os campos seguem o contrato da API', which adds nothing, plus a restriction that payment data belongs in the portal. This does not compensate for the total absence of field-level meaning.

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 opens with a specific verb+resource ('Reemitir servicos adicionais' = reissue additional services) and the title reinforces the 'prepare' framing. It is clearly distinguishable from the many search/query siblings, though it does not name a specific sibling it competes with. One notch below 5 because the resource scope is asserted rather than contrasted against an alternative.

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 gives an explicit workflow: show parameters to the user, then only after explicit confirmation call gover_confirmar_operacao. It also states that new payment data must be entered only in the Gover portal, and that large results route through gover_ler_resultado. Clear when-to-use context, but no explicit when-not-to-use beyond the confirmation gate.

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