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

Annotations already provide readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds the endpoint and category, which is useful, but it does not disclose response format, pagination, authentication needs, or other runtime behavior.

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 a single compact sentence with no filler. It front-loads the category and includes the endpoint, which is useful, but it is slightly too sparse to fully carry the informational load.

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 no output schema and 0% parameter coverage, the description is incomplete for a tool that has two parameters. It does not explain how to construct a valid call or what the agent should expect in return. Annotations cover only the safety profile, not functional usage.

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%, and neither the description nor the schema explains what 'query' or 'account' mean. The description mentions no parameters at all, so an agent cannot tell whether 'query' is a search string, filter, or something else, nor whether 'account' is an ID, name, or code.

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 specific operation ('Listar dados pagamento favorecido') and the endpoint, making the resource unmistakable. It distinguishes the tool from its create sibling by the verb 'Listar.' However, it does not explicitly differentiate it from other list tools beyond the resource name.

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?

There is no guidance on when to use this tool versus alternatives such as superlogica_contatofavorecido_create or other list endpoints. The intended usage is only implied by the tool name and the bare statement, leaving the agent to infer context.

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