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

Beyond the annotations, it discloses the account restriction, lifecycle constraints, revision precondition, and several non-cancellable cases. It does not explain the outcome of a stale revision or whether cancellation is reversible, so some useful operational behavior remains implicit.

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 short sentences front-load the account restriction, then state the valid operation and its exclusions. Every sentence adds actionable information without redundancy.

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?

Together with the annotations and output schema, the description is sufficient for an agent holding the necessary ID and revision to select and invoke the tool correctly. Its main remaining gaps are parameter provenance and behavior when the revision is stale or the request has changed state.

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 0% schema description coverage, the description only partly compensates: 'current revision' clarifies the purpose of revision, while the request wording implies what id identifies. It does not explicitly map both parameters or explain where to obtain the request ID and current revision.

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 clearly identifies cancellation of a queued booking request, rather than booking creation or general ticket deletion. The queued-state and current-revision wording gives the operation a precise scope relative to request_booking and the other 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?

It gives explicit eligibility and preconditions: private executor accounts only, a still-queued request, and its current revision. It also supplies clear when-not guidance by excluding claimed requests, booked tickets, and protected tickets.

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