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

Annotations indicate readOnlyHint=false, so this is a write operation, and the description explicitly notes '[write, altera dados]' which aligns. However, it does not disclose what happens on creation (e.g., whether it is idempotent, error handling, or if it overwrites existing data). The description adds the write flag but no deeper behavioral context.

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 extremely short and front-loaded with the main purpose. However, it is under-specified rather than concise; the few words do not provide enough actionable detail. It is not verbose, but the brevity is a deficiency.

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?

Given the tool has 2 parameters with zero documentation and no annotations that clarify usage, the description is incomplete. It does not explain how to construct the body or select an account, nor does it describe the response. With no output schema, additional detail is expected but absent.

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 explain the parameters. It does not mention 'body' (the payload) or 'account' (which account to use). The description adds no semantic meaning beyond the schema's type declarations, leaving the agent guessing about required fields and format.

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 states the tool creates transportadoras (carriers) via POST /api/transportadoras, which is a specific verb and resource. However, it does not distinguish from the sibling create tools (e.g., gestaoclick_clientes_create) beyond the resource name, and the name itself already implies this. It is clear but minimal.

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 gives no guidance on when to use this tool versus alternatives (e.g., update or list transportadoras). It does not mention any prerequisites like authentication or account selection, even though there is an 'account' parameter. The context is implied by the endpoint but no exclusions or conditions are provided.

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