A3.9/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is clear. The description adds value by stating the data is public, not private or confidential, that the client is data controller under LGPD, and that there is a usage cost involved. This adds context beyond annotations, though it does not describe the response format or rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loaded with the main functionality, followed by relevant operational details. It does not include excessive fluff, though it could be tightened by removing some legal language, but overall it is appropriate in length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core purpose, cost, data accessibility, and legal responsibilities, which is strong context. However, it does not specify the meaning of the 'completo' parameter or describe the expected return structure beyond 'indício de óbito.' Given the lack of an output schema, this leaves some ambiguity for the agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

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 parameters. It clarifies that the CPF is the key input ('a partir do CPF'), but it does not explain the 'completo' boolean parameter. The description leaves this parameter entirely ambiguous, which is a significant gap given the low schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the tool's function: 'Verifica indício de óbito de uma pessoa a partir do CPF, em bases oficiais.' This is a specific verb and resource, clearly distinguishing it from the sibling tools, which are platform utilities rather than data lookup tools. The purpose is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides practical context: it is hosted by the platform, requires no credentials, and is pay-per-query with prepaid credit. This tells an agent when it is appropriate to use this tool (i.e., when CPF lookup is needed and the user has credit), but it does not explicitly exclude alternative approaches or mention any when-not-to-use conditions. Therefore, it offers clear usage context without explicit exclusions.

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