travel_confirm_booking

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

No annotations are provided, so the description must carry the burden. It mentions 'authorized booking' and 'passkey step-up' implying security, but does not disclose side effects, idempotency, rate limits, or whether the action is irreversible. The verb 'confirm' suggests a state change but details are missing.

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 with no wasted words. The core action and timing are front-loaded, achieving maximal clarity with minimal 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?

Given the simple structure (1 param, no nested objects, no output schema) and no annotations, the description provides the essential purpose and usage context. However, it lacks information about return values or error conditions, which would be needed for a complete understanding.

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 coverage is 0% and the description does not explain the 'bookingId' parameter's meaning, format, or constraints. The schema only provides the type, so the description adds no value for parameter understanding.

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 uses specific verb 'confirm' and resource 'authorized booking', clearly distinguishing it from sibling tools like travel_authorize_booking (authorization step) and travel_cancel_booking (cancellation). The phrase 'after passkey step-up' adds precision.

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 explicitly states 'after passkey step-up in a real flow', providing clear context for when to use. However, it does not mention when not to use or direct alternatives beyond the implicit sequence.

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