Desvincular cobrança de uma location Pix

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

The description adds context beyond annotations: it states that the QR Code stops representing that link. Annotations include destructiveHint=true and idempotentHint=true, which are consistent. The description clarifies the behavioral impact on the QR Code.

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 that are front-loaded and contain no extraneous information. Every sentence serves a purpose: first defines the action, second provides usage guidance in a concise manner.

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 a single parameter and an output schema (not shown but exists), the description adequately covers the purpose and usage. It could mention the return value or side effects, but it is complete enough for the complexity level.

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 100% coverage, so the baseline is 3. The description does not add meaning to the 'id' parameter beyond the schema's generic 'Identificador do recurso'. It implies the id is the location identifier but does not explicitly state that.

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 verb 'Remove' and the resource 'vínculo entre uma location e o txid de sua cobrança Pix'. It specifically identifies the action and the entities involved, distinguishing it from siblings like 'pix_unlink_location_recurrence_automatic' which deals with recurrence locations.

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 explicit guidance on when to use the tool: 'antes de reutilizar a location ou encerrar a associação'. This tells the agent the context for invocation. However, it does not mention when not to use it or alternatives, but the given context is sufficient for most cases.

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