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 discloses that the tool completes the purchase and returns an order confirmation, but does not mention idempotency, failure handling, or irreversible actions.
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 two sentences, directly stating the purpose and outcome. Every word earns its place, and it is efficiently structured with the action first.
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 tool's simplicity and the existence of an output schema (not shown), the description covers the main behavior and return. It could mention the prerequisite of having called checkout first, but overall is sufficiently complete.
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?
With 0% schema description coverage, the description adds essential semantics: 'payment_token from checkout' and 'cc_token (credit card token)'. This clarifies origin and type, but lacks format or validation details.
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 the tool confirms payment using two tokens and completes a purchase, returning an order confirmation. The verb 'confirm payment' is specific to the resource, and it is well-distinguished from siblings like 'checkout' which initiates the process.
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 phrase 'from checkout' implies this tool is used after the checkout step, providing clear context. However, it lacks explicit when-not-to-use guidance or comparison with alternatives like checkout.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool has a distinct purpose in the purchase flow: searching products, getting details, adding to cart, checking out, and confirming payment. No overlap in functionality.
All tool names follow a clear verb_noun pattern in snake_case (e.g., add_to_cart, get_product). Even 'checkout' is a standard verb that fits the pattern.
Five tools cover the core e-commerce workflow without redundancy. The number is appropriate for the server's purpose of handling basic store operations.
The set covers the essential purchase lifecycle from search to payment confirmation. Minor gaps like cart modification or order history are absent but not critical for a basic store.
