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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method (GET) and endpoint, which confirms the read-only nature. However, it does not add further behavioral details such as pagination, response format, or any side effects, but given the annotations, the description meets the baseline.

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 extremely concise, one sentence, and includes the resource name and HTTP method. It is front-loaded and wastes no words, though it could have used a bit more space to clarify parameters or usage.

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 minimal description, the tool is under-specified. The tool complexity is low (list operation), but the two parameters are completely unexplained, and there is no guidance on expected return. Given the lack of parameter semantics and usage guidance, the description is incomplete for reliable invocation.

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 explain the 'query' or 'account' parameters at all. The schema only provides type string with no descriptions, so the agent has no clue what these parameters mean or how they affect the listing. The description must compensate but fails to do so.

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's purpose: listing employees via GET /api/funcionarios. It specifies the resource (funcionarios) and the action (listar/list). While it does not explicitly differentiate from siblings, the resource name is unique among the many list tools, so the purpose is clear.

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 provides no explicit guidance on when to use this tool versus alternatives. It only states the HTTP endpoint. There are no exclusions, prerequisites, or mention of other tools for filtering or retrieving specific records. The usage context is implied by the resource name but not articulated.

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