Remover webhook de uma chave Pix

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

Annotations already indicate destructiveHint=true, readOnlyHint=false, idempotentHint=true, and openWorldHint=true. The description adds that the webhook is removed and notifications stop, which is consistent but does not provide additional behavioral insights beyond what the annotations convey.

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?

Two sentences, no redundancy. Information is front-loaded: purpose first, usage second. Every word adds value.

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?

For a simple tool with one parameter, the description is nearly complete. It covers purpose, usage, and effect. The presence of an output schema reduces the need to explain returns. Could marginally mention prerequisites (e.g., webhook must exist), but not essential.

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 covers 100% of parameters with descriptions. The tool description does not add further meaning to the 'chave' parameter beyond what is already in the schema. Baseline 3 is appropriate.

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 action (removing webhook configuration) and the associated resource (chave Pix). It distinguishes from siblings like pix_config_webhook or pix_list_webhook by focusing on deletion. The effect (cessation of event delivery) is explicit.

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 a clear use case: when a destination should no longer receive events. It implicitly advises against using when events are still desired. While it lacks explicit mention of alternatives, the context is sufficient for an agent to decide when to invoke.

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