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

The description adds 'altera dados' (changes data) and mentions bulk support, which are useful behavioral traits beyond the annotations' readOnlyHint=false. However, it does not disclose the irreversibility of deletion, potential cascading effects, or any permission requirements. Given that annotations already indicate write (readOnlyHint=false), the description adds limited extra context, though it does note the batched execution capability.

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 two short sentences, front-loaded with the purpose (resource and verb) and followed by a single note on bulk support. It contains no fluff or repetitive information, making it highly concise and easily scannable.

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 there is no output schema, the description should explain expected return values or error handling, but it does not. It also lacks clarification on the 'body' and 'account' parameters, and does not describe any side effects or prerequisites. For a delete operation with multiple params and no output schema, the description is incomplete, leaving substantial ambiguity for an agent.

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 schema has 4 parameters with 0% description coverage, so the description must compensate. It only explains that 'ids' provides bulk support, clarifying that parameter partially. However, it does not explain the 'body' or 'account' parameters at all, and it only implicitly handles 'id' via the endpoint URL. This leaves major gaps in parameter understanding.

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: 'Pagamentos: Deletar' (Payments: Delete) and provides the endpoint 'DELETE /api/pagamentos/{id}'. This distinguishes it from sibling payment tools (create, get, list, update) by explicitly naming the HTTP DELETE verb and resource. The bulk support note also adds a distinct capability.

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 implicitly indicates this tool is for deleting payment records, but it does not explicitly explain when to use it versus other delete tools (e.g., recebimentos_delete) or mention any prerequisites or conditions. There is no guidance on when not to use it or alternatives, leaving the agent to infer usage from the resource name alone.

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