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

With no annotations, the description carries the behavioral burden and does well by disclosing the conditional delivery behavior and the Coinbase payment COMPLETED prerequisite. It does not cover error cases such as invalid claim_secret or list possible status values, but the main behavior is transparent.

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 sentences, front-loaded with the core return behavior and followed by the important claim_secret condition. There is no wasted text.

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 description covers the two main invocation modes and the payment-completion gate, which is enough to call the tool. However, with no output schema and no annotations, it could do more to describe response shape, possible status values, or error behavior for an invalid claim_secret.

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 coverage is 50%, and the schema already explains that without claim_secret only status is returned. The description adds useful context that claim_secret is returned once when the order opens and gates delivery on payment completion, but order_id remains self-evident and undocumented.

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 states a specific verb and resource: it returns order status, and with claim_secret includes delivery. This is clear, though it does not explicitly differentiate from any sibling because no sibling overlaps this order-specific resource.

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?

It clearly explains the key usage condition: without claim_secret only status is returned, and with claim_secret the delivery is included once payment is COMPLETED. It does not name alternatives or explicit exclusions, but for this tool the main conditional is covered.

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