Create Yolfi Paylink

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

Annotations are sparse (readOnlyHint, destructiveHint, idempotentHint all false, openWorldHint true). The description only adds the approval requirement, but does not disclose other behavioral traits like idempotency, error behavior, or authority needs. For a creation tool, more context is needed.

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 clear sentence that is front-loaded with the main action. It is concise and to the point, though slightly more structure could improve readability.

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 8 parameters (including nested objects) and no output schema, the description is minimal. It does not explain return values, what happens if recurringInterval is provided for ONE_TIME, or other important context. Incomplete 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?

Schema coverage is 100% (all parameters with descriptions). The description text adds 'user-approved' context but does not provide additional meaning beyond what the schema already says. 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 it creates a Yolfi payment link, which is a specific verb+resource. The name already distinguishes it from siblings like 'yolfi_paylinks_disable'. However, it could be more explicit about what a paylink is, but the purpose is clear.

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 explicitly states a precondition: 'only after the user approves...', which guides when to use the tool. It implies not to use it without prior approval, but does not explicitly mention alternatives or when not to use it.

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