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

Annotations indicate read-only and non-destructive; the description adds that it is hosted without platform credentials, paid per query, and that data is not confidential with LGPD responsibility, providing useful operational context.

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 reasonably concise, opening with the main purpose and adding payment and legal context in three sentences; it is not overly verbose.

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 no parameter details, the description leaves out critical usage information such as how to query by chassi vs renavam and what the response will contain; it provides compliance/payment context but lacks operational completeness.

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 the description does not mention any of the six parameters (chassi, renavam, login_cpf, login_senha, pkcs12_cert, pkcs12_pass), leaving their purpose and usage unexplained.

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 'DETRAN BA: Veículo, consulta em fonte oficial' and elaborates that it queries official Brazilian sources, distinguishing it from sibling platform utilities like authenticate and marketplace.

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 context of a vehicle consultation for DETRAN BA with prepaid credit is clear, but no explicit 'use when' or alternatives are given; however, the sibling list contains only generic tools, so the usage is evident.

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