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

Annotations already indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false. The description adds no additional behavioral context beyond the endpoint. It does not contradict annotations, but it also does not disclose filtering behavior or response semantics.

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 short and to the point, which is appropriate for a simple list tool. However, the lack of parameter explanation is a bigger issue than conciseness; structure is acceptable but under-specified.

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 2 parameters with 0% schema coverage, no output schema, and no behavioral description beyond annotations, the description is incomplete. An agent cannot correctly invoke this tool without additional parameter details. The sibling tools do not provide context for this specific one.

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%. The description does not explain the 'query' or 'account' parameters at all. The agent has zero guidance on what these parameters are for, making it impossible to use them correctly. This is a critical gap.

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 states it lists services via GET /api/servicos, but it is minimal and could be confused with other list tools (e.g., gestaoclick_produtos_list, gestaoclick_clientes_list) even though the resource is named. The verb 'Listar' is clear, but it does not explain what qualifies as a 'serviço' or the scope of listing.

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?

There is no guidance on when to use this tool versus other list tools or how to use the 'query' and 'account' parameters. No alternative tools are mentioned. The description simply maps to an endpoint, leaving the agent to infer usage from context.

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