cancel_booking

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

No annotations are provided, so the description carries the full behavioral burden, and it delivers almost nothing: it does not say whether cancellation is irreversible, whether it requires authorization, whether fees/refunds apply, or whether it is idempotent. Only the implicit destructiveness of 'cancel' conveys any behavioral signal.

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?

One short, front-loaded sentence with zero wasted words. It is efficient, though the brevity is the same sparseness that leaves behavioral and usage gaps.

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 trivial one-parameter destructive tool with no annotations and no output schema, the description is minimally viable but leaves the agent without irreversibility, authorization, or post-cancel state information that matters for a mutation.

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 a single required parameter at 100% schema description coverage, the schema already fully documents booking_id. The description adds no format, range, or lookup detail beyond what the schema states, so baseline 3 applies.

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?

States a specific verb+resource ('Cancel a booking') and the identifier it operates on, which lets an agent separate it from book_room and my_bookings without opening the schema. It stops short of any sibling differentiation or scope statement, so it is clear but not exemplary.

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?

There is no guidance on when to cancel versus rebooking, no prerequisite such as ownership or booking state, and no mention of an alternative tool. The agent must infer the entire usage context from the name alone.

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