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

No annotations are provided, so the description carries the full behavioral burden. The verb 'Consulta' implies a read-only operation and the description discloses data scope plus the YYYYMM date constraint. But it says nothing about response shape, pagination limits, or other operational behavior that an agent would need to know when invoking it.

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 sentences with zero waste: the first states purpose and scope with concrete payment-method examples, the second pins down the required date format with a worked example. Purpose is front-loaded.

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 query tool with 4 parameters and 1 required, the description plus fully-covered schema provide the essentials: what it does, its monthly scope, and the required parameter format. A brief note on the return shape would strengthen it, especially given the absence of an output schema, but nothing critical is missing for invoking it 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 100%, so the baseline of 3 applies. The description's YYYYMM format guidance merely repeats what the schema already states for ano_mes and adds nothing new about top, skip, or filtro.

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?

Specific verb 'Consulta' (query) plus a clear resource: 'dados mensais sobre meios de pagamento', with explicit scope enumeration (boletos, PIX, TED, DOC). The 'mensal' qualifier inherently separates it from the 'trimestral' sibling, so an agent can tell them apart without opening either tool.

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 establishes clear usage context by stating this tool covers monthly data, which implicitly contrasts with the quarterly payment-method sibling. However, it never explicitly names the alternative or states a when-not-to-use condition, leaving the routing to inference.

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