cancel_reservation

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 explicitly flags the operation as DESTRUCTIVE and IRREVERSIBLE, warns to confirm with the user, and discloses the refusal-if-mismatch behavior. It does not describe what happens to dependent resources beyond 'its environment' or return-value behavior, but for a cancellation tool the core destructive contract is well disclosed.

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?

Three dense sentences with zero waste. The destructive warning (ALL CAPS) is front-loaded, the confirmation requirement and name-match rule are delivered precisely. Every sentence earns its place.

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 destructive 2-param tool with an output schema, this description is nearly complete. It covers the critical destructive nature, the confirmation requirement, the confirm_name constraint, and refusal behavior. It could arguably mention what the returned output indicates, but the output schema exists to cover that. Sibling differentiation is implicitly clear via the destructive framing.

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 0%, so the description must compensate. The description explains the semantic role of confirm_name (must equal the reservation's exact name from list_reservations, refused if mismatched). It does not elaborate on reservation_id's source or format, but the description gives enough context that the agent can reasonably infer it comes from list_reservations/get_reservation.

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 states a specific verb ('Cancel (delete)') and resource ('a TechZone reservation and its environment'), clearly distinguishing from siblings like extend_reservation, get_reservation, and list_reservations. The destructive scope (reservation AND its environment) is explicit, making the tool's purpose unambiguous.

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 explicitly states when a pre-condition applies ('always confirm with the user first'), and documents the required confirmation behavior. It clearly explains that confirm_name must match the reservation's exact name from list_reservations, giving the agent actionable guidance on correct usage and the refusal behavior.

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