create_checkout

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

No annotations provided. Description reveals only that a URL is created, but does not disclose side effects, required authentication, or what happens with the URL (e.g., it must be presented to user). Minimal behavioral 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?

Single sentence that is direct and free of unnecessary words. Efficiently communicates the core action.

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 no annotations, no output schema, and sibling tools like 'allowance_create', the description is incomplete. It does not explain what the checkout URL returns, how to use it, or prerequisites. Leaves significant gaps for an agent.

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?

Input schema covers both parameters with descriptions, achieving 100% coverage. Description does not add extra meaning beyond the schema, so baseline 3 is appropriate.

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?

Description clearly states it creates a Stripe checkout URL for funding agent allowance via credit card. It uses specific verb+resource and distinguishes from siblings like 'allowance_create' and 'tier_checkout'.

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?

Description implies use when the agent needs human funding, but lacks explicit guidance on when not to use or alternatives. Could be improved by noting that it requires user interaction.

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