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

Annotations already declare readOnlyHint and idempotentHint, so safety is clear. The description adds that bulk support via 'cliente_ids' is available, but does not detail behavior such as rate limits, response format, or pagination limits, providing some added value but not deep transparency.

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 with two sentences, front-loading the purpose. It is concise and efficient, though a more structured list of parameters could improve readability. No wasted words.

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?

With 8 parameters, no output schema, and 0% schema coverage, the description is insufficient. It lacks details on return structure, pagination behavior, error handling, and the 'account' parameter. Significant gaps remain despite annotations covering safety.

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%, so the description must compensate. It lists several parameters and notes a date format (YYYY-MM-DD), but does not provide details on value ranges, allowed values for status_venda, or explain the 'account' parameter present in the schema. Parameter semantics are only partially addressed.

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 'Lista vendas' (List sales) with a specific verb and resource. It lists relevant filters, distinguishing it from sibling tools like 'contaazul_get_sale' which retrieves a single sale, though it does not explicitly contrast them.

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 lists available filters and mentions bulk support, guiding basic usage. However, it does not specify when to use this tool over alternatives (e.g., for a single sale use get_sale) or any prerequisites, providing minimal contextual guidance.

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