parlayapi_checkout_link

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 only says 'generate a URL' but doesn't disclose whether a Stripe Checkout session is created, whether generation triggers any charge or email, or whether the link expires. For a payment-adjacent action, those behaviors matter.

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 short sentences with no filler. The action is front-loaded in the first sentence, and the second gives a relevant dependency in a clear, scannable way.

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?

The purpose and pricing dependency are present, and since an output schema exists, return-value details are not required. However, the missing side-effect disclosure and lack of parameter semantics make this only minimally complete for an agent deciding whether and how to call it.

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%, and the description never mentions the email or tier parameters. It adds zero meaning beyond the bare field names and default value in the schema, leaving the agent without guidance on how to populate the required arguments.

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 'Generate' plus a specific resource 'Stripe Checkout URL' and purpose 'upgrade'. This is immediately distinguishable from siblings like odds, pricing, and search tools, and the pointer to get_pricing reinforces the intended action.

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?

Explicitly directs the agent to parlayapi_get_pricing for current tiers and prices, establishing a useful sequencing rule before generating the link. It doesn't explicitly state when not to use this tool (e.g., for magic link or signup), so it stops short of a 5.

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