cancel_document_checkout

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

Despite no annotations, the description explains return behavior (Document object on success, ToolError on failure) and parameter priority behavior, providing good transparency beyond what the schema offers.

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 reasonably concise but includes docstring-style param/return formatting that could be streamlined. It is front-loaded with the purpose.

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?

Given only one parameter and an output schema, the description covers the tool's behavior and parameter semantics adequately. It is complete for a simple tool.

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?

The description adds significant meaning to the single parameter 'identifier', explaining it can be a reservation_id or document_id with priority, which the input schema does not convey.

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 states it cancels a document checkout, with a specific verb and resource. It distinguishes itself from sibling tools like 'checkout_document' and 'checkin_document'.

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 does not explicitly provide when to use this tool vs alternatives, nor does it mention prerequisites or context. It only implies usage when a checkout needs cancellation.

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