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

The description explicitly says 'Deletar' and '[write, altera dados]', which indicates a destructive write operation. This directly contradicts the annotation `destructiveHint: false`. Therefore, the description contradicts the annotations, warranting a score of 1.

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 concise, with two sentences. It front-loads the core operation, HTTP method, endpoint, and a write signal, then adds the bulk execution feature without any redundancy.

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 delete tool with 4 parameters and no output schema, the description only addresses `id` and `ids`. It omits any explanation of `body` and `account`, and does not mention irreversibility or response behavior, making it incomplete for an agent to use 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%, so the description must compensate. It explains the `id` parameter through the endpoint path and `ids` through the bulk support note, but it says nothing about the `body` or `account` parameters, leaving them 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?

The description clearly states the operation is deleting transportadoras with the HTTP DELETE method and endpoint. It distinguishes this tool from sibling create/get/list/update tools for the same resource.

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 some usage context by mentioning bulk support via the `ids` parameter for batched execution. However, it does not explicitly discuss when to use this tool versus alternatives, such as when an update would be more appropriate.

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