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

The annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the description adds little beyond the HTTP method. It does not mention pagination, filtering behavior, or what the response contains, missing an opportunity to add context beyond the annotations.

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 concise with no waste, but it is under-specified. A single phrase is efficient but not appropriately sized for a tool with undocumented parameters and no output schema.

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 list tool, the description is incomplete: it lacks any mention of return structure, filtering semantics, or parameter relevance. The absence of an output schema makes this gap more significant.

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?

The schema has two parameters (query, account) with zero descriptions, and the description does not explain their meaning or usage. With 0% schema description coverage, the description was expected to compensate but fails entirely.

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 action ('Listar') and the resource ('Recebimentos'), plus the HTTP endpoint, which distinguishes it from create/get/update/delete siblings. However, it does not differentiate from other list tools in the sibling set, so not a 5.

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?

No guidance is given on when to use this tool versus alternatives like gestaoclick_recebimentos_get for single-record retrieval, or how it differs from other list endpoints. The description merely states the operation without context or exclusions.

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