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

No annotations are provided, so the description carries full burden. It states it 'gets details,' implying a read-only operation, but doesn't disclose behavioral traits like authentication requirements, rate limits, error conditions (e.g., invalid payment method number), or what 'details' include (e.g., type, status, expiration). This leaves gaps for safe agent invocation.

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 appropriately sized and front-loaded with the core purpose in the first sentence. The Args section is structured but could be more integrated; overall, it avoids unnecessary verbosity while covering basics efficiently.

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's low complexity (1 required parameter) and the presence of an output schema (which handles return values), the description is reasonably complete. It covers the purpose and parameter semantics adequately, though it lacks behavioral context and usage guidelines, which are minor gaps in this simple read scenario.

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 description coverage is 0%, so the description must compensate. It adds meaning by explaining 'payment_method_number' as a 'Payment method identifier,' which clarifies its role beyond the schema's generic 'string' type. However, it doesn't provide format examples (e.g., numeric, UUID), source hints, or validation rules, leaving some ambiguity.

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 as 'Get details of a specific payment method,' which is a specific verb (get) and resource (payment method). It distinguishes itself from siblings like 'netlicensing_list_payment_methods' (which lists multiple) and 'netlicensing_update_payment_method' (which modifies), but doesn't explicitly mention these distinctions in the description itself.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a valid payment method number), contrast with 'netlicensing_list_payment_methods' for browsing, or specify use cases like verifying payment method details before an update.

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