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

No annotations are provided, so the description carries full burden for behavioral disclosure. While 'List all payment links' implies a read-only operation, it doesn't mention pagination behavior (implied by limit/offset parameters), authentication requirements, rate limits, or what 'all' means in practice (e.g., active only, includes archived). The description is minimal and lacks important operational context.

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, efficient sentence that states the core purpose without any wasted words. It's appropriately sized for a simple listing tool and gets straight to the point.

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 listing tool with 2 parameters and no output schema, the description is insufficiently complete. It doesn't explain what information is returned about payment links, how results are ordered, whether filtering options exist, or what happens when no payment links are found. The lack of annotations exacerbates these gaps in operational understanding.

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 100%, with both parameters (limit and offset) clearly documented in the schema. The description doesn't add any parameter semantics beyond what the schema provides, so it meets the baseline of 3 for adequate coverage without adding value.

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 ('List') and resource ('all payment links in your account'), making the purpose immediately understandable. However, it doesn't distinguish this tool from sibling list tools like list_customers or list_invoices, which follow the same pattern but target different resources.

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. There are multiple sibling list tools (e.g., list_customers, list_invoices) and a specific get_payment_link tool for retrieving individual payment links, but the description doesn't mention any of these or provide context about when this listing approach is preferred.

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