cancel_document_checkout

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

No annotations are provided, so the description carries full burden. It discloses that the tool returns a Document object on success and a ToolError on failure, and explains the identifier parameter's dual nature and prioritization. However, it could be more explicit about side effects like unlocking the document or permission requirements.

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 very concise: two paragraphs with no fluff. The first sentence states the core functionality, followed by a clear parameter description and return value documentation. Every sentence serves a 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?

For a tool with one required parameter and an output schema (not shown), the description covers the parameter semantics and return value. It could improve by providing examples or clarifying how the identifier string distinguishes between reservation_id and document_id, but it is largely complete.

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 coverage is 0%, so the description must explain the parameter. It does so thoroughly: identifier can be reservation_id or document_id, with reservation_id prioritized. This adds significant meaning beyond the schema's 'string' type.

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 the verb 'cancels' and the resource 'document checkout', making the tool's purpose unambiguous. It is distinct 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 implies that the tool is used to undo a checkout, but it does not explicitly state when to use it or when not to, nor does it mention alternatives. The context from sibling tools helps, but the description itself lacks explicit guidance.

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