confirm-booking

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It indicates the core mutation—confirming a pending booking—but does not state side effects, error behavior, idempotency, permission requirements, or whether the booking must currently be in a specific status.

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 extremely concise at four words and front-loads the core action and target. No filler or redundant phrasing exists, and the simplicity of the tool warrants this brevity.

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 tool is simple with one well-documented parameter, but no output schema or annotations exist. The description is adequate for a basic understanding but does not cover return values, potential errors, or state preconditions, leaving an agent to infer some behavior.

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%, and the single parameter 'bookingUid' already has a clear description. The tool description adds no additional meaning beyond the schema, which is acceptable given the high schema coverage.

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: 'Confirm a pending booking.' It clearly communicates the action and target, and the word 'pending' distinguishes this from related operations like cancel, decline, or reschedule, though it does not explicitly name siblings.

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 no explicit guidance on when to use this tool versus alternatives such as cancel-booking, decline-booking, or reschedule-booking. The phrase 'pending booking' implies it should be used for bookings awaiting confirmation, but no when-to-use or when-not-to-use guidance is given.

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