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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states the basic action (listing items) and the endpoint. It does not mention read-only nature, pagination behavior (though schema covers it), error handling, required permissions, or any side effects. The description adds minimal behavioral context beyond the function name.

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 very short: two sentences—one functional statement and one endpoint path. It is front-loaded with the purpose. No fluff, but it is perhaps too brief given the lack of annotations and the need for more context. Still, it earns its place.

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?

Given the tool has 3 parameters, an output schema, and many sibling tools, the description is incomplete. It does not explain how to obtain the required id_contratacao (though the schema hints at it), does not describe pagination behavior, and does not distinguish from similar siblings. The tool needs more context for effective use.

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 100% (all 3 parameters have descriptions), so the baseline is 3. The description does not add any additional parameter meaning beyond what the schema already provides. It mentions the endpoint but not the parameters. No extra context or clarification is given.

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 tool lists items of a specific contract under law 14.133, using 'Lista itens de uma contratação 14.133 específica.' It names the endpoint and resource. However, it does not differentiate from the sibling tool 'compras_contratacoes_14133_itens_listar', which could have a similar scope, reducing clarity slightly.

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 usage when you have a specific contract ID, but it gives no guidance on when to use this tool versus alternatives like 'compras_contratacoes_14133_itens_listar' or 'compras_contratacoes_14133_consultar'. There is no mention of prerequisites, when-not-to-use, or conditional context.

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