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

The description's '[write, altera dados]' simply restates the annotation readOnlyHint=false and adds no meaningful behavioral context. It does not mention authentication requirements, side effects, idempotency caveats, or response behavior. There is no annotation contradiction, but the description adds no transparency beyond what annotations already declare.

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 a single, front-loaded phrase that includes the operation, endpoint, and mutation flag without unnecessary filler. It is concise, though the brevity sacrifices useful parameter and usage context.

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?

Even for a simple create tool, the description fails to explain the body payload, the meaning of the account parameter, or what a successful creation returns. The absence of an output schema and 0% parameter coverage makes this description insufficient 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?

The input schema has two string parameters, body and account, with 0% schema description coverage, and the description provides no explanation of what these values should contain or how they are used. The agent cannot determine the expected format or purpose of either parameter from the available information.

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 explicitly states 'Cadastrar' with the endpoint POST /api/pagamentos, clearly identifying a payment creation operation. This distinguishes it from sibling tools like gestaoclick_pagamentos_update, gestaoclick_pagamentos_get, and gestaoclick_pagamentos_list.

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 verb 'Cadastrar' and endpoint imply this tool is for creating payments, but there is no explicit guidance about when to use it versus updating existing payments or using other payment-related tools. No prerequisites, exclusions, or alternative tool references are provided.

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