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

Annotations declare readOnlyHint=false, destructiveHint=true, idempotentHint=true. The description adds the critical behavioral nuance beyond annotations: this is a non-executing preparation step requiring explicit user confirmation before the real operation. This two-phase workflow context is genuinely useful; the mild tension with destructiveHint=true is not a direct contradiction since it merely prepares a potentially destructive action.

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 compact sentences, front-loaded with the core purpose and ending with the routing constraint. No filler; efficient for the content provided.

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?

Covers the workflow and confirmation requirement well, and no output schema exists so return values need no explanation. However, given 5 parameters including a nested itens array and zero schema description coverage, the definition leaves parameter usage entirely unexplained, which is a meaningful gap for a complex input.

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 adds no meaning for any of the 5 parameters (solicitacaoId, acao, itens, nivel, justificativa). It only implies the acao dimension via the title's aprovação/reprovação/cancelamento wording, leaving the nested itens and justification/nivel fields undocumented.

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?

States a specific purpose: consult current state, show target and impact, and prepare the decision. It distinguishes itself from the execution step by naming gover_confirmar_operacao, so an agent can tell what this tool does versus the confirmation tool.

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?

Explicitly says it executes nothing and routes the agent: use gover_confirmar_operacao only after explicit user confirmation. The when/when-not against the sibling is clear, though it does not discuss the aprovar/reprovar/cancelar variants beyond the enum.

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