cancel_reservation

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

Annotations are absent, so the description must carry the full burden of behavioral disclosure. It signals destructive intent through 'delete/release,' but it does not disclose consequences such as resource release, irreversibility, permission requirements, or behavior when the reservation does not exist or is already canceled.

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 a single, front-loaded sentence with no filler words. It communicates the core action, target, and input requirement efficiently.

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 one-parameter tool with no annotations and no output schema, this description is minimally viable but incomplete. It omits side effects, prerequisites, success/failure feedback, and any conditions under which cancellation should happen.

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 needs to compensate. It only restates that the action happens 'by id,' which adds little beyond the schema's reservation_id parameter name and integer type. Valid values, edge cases, and meaning of the id are not clarified.

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 uses concrete action verbs ('Delete/release'), names the resource ('GLPI reservation'), and specifies the targeting mechanism ('by id'). It is clearly distinguishable from all sibling tools, none of which perform cancellation or deletion of a reservation.

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 about when to use this tool versus sibling tools like reserve_cluster, check_availability, or list_reservable_items. It also does not mention prerequisites, reversibility, or what conditions should hold before calling it.

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