kinematic_checkout

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

Since no annotations are provided, the description carries the behavioral disclosure burden. It states that checkout creates an order, that payment happens on-chain via Solana, and that provisioning is asynchronous via polling. It does not discuss idempotency, memo mismatch failures, or order expiration, but the core mutation and required user action are clear.

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 three sentences with zero filler. It front-loads the main action, then provides the payment step and polling follow-up, including an explicit warning about sending the memo exactly as given.

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 single-parameter tool with no output schema, the description explains the return value (wallet, memo, amount), the follow-up status tool, and the asynchronous provisioning flow. It omits edge cases like invalid memo or order failure, but the essential calling contract is covered.

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%, so the schema already documents the single email parameter as the delivery email. The description adds no extra detail about the parameter, matching the baseline for fully covered 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 opens with 'Buy a private Kinematic Drive with USDC', a specific verb and resource, then explains that it creates an order and returns payment instructions. It explicitly contrasts with kinematic_checkout_status, allowing an agent to distinguish checkout from status polling.

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 a clear workflow: call this to create an order, send USDC with the returned memo, then poll kinematic_checkout_status. It gives concrete context for when this tool is used, though it does not enumerate exclusion criteria or direct alternatives beyond the polling sibling.

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