checkout_document

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does reveal important behavior: a user prompt may occur if 'download_folder_path' is missing but needed. It also specifies return types (Document object or ToolError). However, it does not disclose side effects like locking or reservation creation, which are critical for an agent reasoning about checkout operations.

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 well-structured with a clear lead sentence, parameter documentation in a standard docstring format, and a return statement. While it is somewhat verbose, every sentence adds value and no information is redundant with the schema. The front-loading of the action helps agents quickly understand the tool's 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 the tool's complexity (4 parameters, some nested) and the presence of an output schema (not shown but detected), the description provides adequate coverage. It explains all parameters, the return type, and a unique behavioral note about user prompts. It could mention the effect on document state (e.g., reservation creation) but overall is sufficiently complete for an agent to use the tool correctly.

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 input schema has 0% top-level description coverage (no descriptions for the four primary parameters). The description compensates well by clearly explaining each parameter: identifier (ID or path), document_properties (properties to update), checkout_action (action parameters), and download_folder_path (optional with prompt behavior). This adds significant meaning beyond the raw schema.

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 first sentence clearly states the tool's action ('Checks out a document') and the resource ('content repository'). The description also clarifies that the identifier can be an ID or path, which adds specificity. However, it does not explicitly differentiate from sibling tools like 'checkin_document' or 'cancel_document_checkout', relying on the tool name for distinction.

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 lacks any guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., document not already checked out) or context (e.g., typical workflow steps). The detailed parameter documentation implies usage but does not help the agent decide between checkout and other related tools.

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