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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the read-only nature is clear. The description adds the POST method and pagination details, providing some context beyond annotations. However, it does not disclose potential rate limits, default values, or response behavior, which are common gaps for a read endpoint. This is adequate but not exceptional, consistent with a score of 3.

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 concise, fitting the essential info into one sentence with backtick formatting for parameters. It avoids redundancy and is easy to scan. Minor deduction for cramming the endpoint into parentheses within a single long sentence, but it remains efficient.

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 straightforward query tool with 3 parameters and no output schema, the description covers the basics: purpose, filter semantics, and pagination. However, it omits default values for pagination and any mention of the response shape, which agents may need. This is a minimum-viable description for the tool's complexity, hence a 3.

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 coverage is 0%, so the description must compensate. It explains that 'filtro' holds filter criteria per the API and that 'pagina'/'quantidade_registros' handle pagination. While this provides basic meaning, it leaves out the structure of 'filtro' (a nested object) and any default/constraint details, making the guidance incomplete. A score of 3 reflects this partial but not thorough compensation.

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 uses a specific verb 'Busca' (searches) and a clear resource ('Atendimentos (CRM/relacionamento)'), which precisely states what the tool does. It distinguishes itself from siblings by naming the domain (Atendimentos) and the underlying endpoint (POST /atendimento/consulta). No ambiguity remains about the tool's purpose.

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 implies when to use it: to search for Atendimentos by filters, with pagination instructions. It does not explicitly name alternatives or exclusions, but the scope is clear given the many sibling 'consulta' tools. This matches a score 4: clear context without explicit when-not-to-use guidance.

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