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

No annotations are provided, so the description carries the full burden. It implies a write operation ('Create') and mentions redirect URLs for payment outcomes, which adds some behavioral context. However, it lacks details on permissions, rate limits, error handling, or what the created checkout looks like (e.g., a link or object). For a mutation tool with zero annotation coverage, this is a moderate gap.

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 well-structured with a brief purpose statement followed by a parameter list. Each parameter explanation is concise and informative. However, the list is lengthy (18 items), which might overwhelm, but every sentence earns its place by clarifying complex parameters.

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 complexity (18 parameters, 7 required) and no annotations, the description does a good job explaining parameters and implying behavior. An output schema exists, so return values needn't be described. It covers most essentials but could improve by adding usage guidelines and more behavioral details like error cases.

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 fully. It provides detailed semantics for all 18 parameters, including examples (e.g., 'MXN' for currency, '50000 for $500.00 MXN' for price), defaults, and constraints (e.g., '10 minutes to 365 days from now' for expires_at). This adds significant value beyond the bare schema.

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: 'Create a payment link (checkout).' It specifies the verb ('Create') and resource ('payment link/checkout'), making it unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'create_order' or 'create_subscription', which might also involve payment processing.

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 like 'create_order' or 'create_subscription'. It lists parameters but doesn't explain prerequisites, typical use cases, or exclusions. Without this context, an agent might struggle to choose between similar payment-related tools.

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