netlicensing_update_payment_method

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

No annotations provided, so description carries full burden. It states 'Update' but does not disclose side effects (e.g., overwrite vs. merge), authentication needs, or what happens to unspecified fields. No mention of return value despite an output schema being present.

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 plus an arg list. Purpose stated immediately, parameters listed clearly. No fluff or unnecessary detail.

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?

Despite low parameter count and no enums, the tool has 3 parameters, an output schema, and no annotations. Description omits return value, potential errors, and any behavioral constraints (e.g., what happens if active is null). Incomplete for an update operation.

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 0%, so description must compensate. It adds brief clarification: 'Enable or disable the payment method' for the boolean field, and 'PayPal account e-mail address' for the string. However, 'Payment method to update' is nearly redundant with the parameter name, and no additional semantics are provided for defaults or constraints.

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?

Clear verb+resource: 'Update a payment method's configuration.' Distinguishes from sibling update tools (e.g., netlicensing_update_license) by specifying the payment method resource.

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?

No guidance on when to use this tool vs. alternatives (e.g., get, list). The description does not mention prerequisites or situations where other tools would be more appropriate.

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