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

The description adds minimal behavioral insight beyond annotations. It restates the write nature via '[write, altera dados]', which is already conveyed by readOnlyHint=false. It does mention the HTTP method, but this is not a meaningful behavioral disclosure for the agent.

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 readable, but it includes redundant phrases like '[write, altera dados]' that repeat annotation information. It is not overly verbose, but it also fails to add necessary detail, making it somewhat wasteful in its brevity.

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 create operation, the description is incomplete. It does not explain what data the 'body' should contain, how 'account' is used, or what the response looks like. Given the lack of an output schema and annotations, this is insufficient for an agent to execute the tool 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?

The schema has 0% coverage and the description does not explain the 'body' or 'account' parameters at all. With only two string parameters and no descriptions, the agent has no idea what values these should take, making the tool effectively unusable without external knowledge.

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 tool's purpose: to create (Cadastrar) a sale (Vendas), specifying the HTTP method (POST) and endpoint (/api/vendas). It distinguishes itself from sibling tools like gestaoclick_vendas_get, list, update, and delete by clearly indicating its create semantics.

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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention when to use create vs update or any exclusions, leaving the agent to infer usage from the name alone.

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