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

The description adds the HTTP endpoint and clarifies that `data` is the official API body, but it doesn't disclose validation, error/response behavior, or prerequisites. Annotations mark false for read-only and destructive, adding little beyond what the description itself implies.

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 short, front-loaded sentences contain only useful information: what is created, the endpoint, and what `data` represents. No filler or 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 simple one-parameter create wrapper with no output schema, this description is sufficiently complete. Adding more detail about required fields would depend on the external official API, which is reasonably referenced.

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 coverage is 0%, so the description must compensate for the single `data` parameter. Saying `data` is the body per the official API provides essential meaning beyond the bare schema, although it remains open-ended.

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?

Description clearly states 'Cria um(a) Atendimentos (CRM/relacionamento) (POST /atendimento)', identifying the action and resource. This distinguishes it from sibling consult/get/update tools for the same entity.

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 intended use is clear: create an Atendimento record via POST. It doesn't explicitly name alternative tools, but the create action versus consult/update siblings makes the usage context obvious.

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