close_document

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

With no annotations, the description must disclose all behavioral traits. It mentions 'clean up temporary files' as a side effect but omits important details: whether changes are saved, what happens on error, or if the operation is reversible. Significant gaps.

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 short (2 sentences) with no superfluous information. It is front-loaded with purpose and then parameter detail. Could be slightly more structured, but efficient.

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 has one parameter, an output schema (though not described), and no annotations, the description covers the core action. However, it lacks explanation of return value, error cases, or prerequisite state (e.g., document must be open). Adequate but not thorough.

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 compensate. It adds meaning for the sole parameter: 'Handle of the document to close. Empty = __default__ slot.' This clarifies the default behavior, which is not in the schema. Adequate for one parameter.

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 'Close a document and clean up temporary files,' specifying the verb and resource. It distinguishes from siblings like open_document and save_document. However, it could be more precise about what 'close' entails (e.g., state changes, unsaved changes).

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?

No explicit guidance on when to use this tool vs. alternatives (e.g., save_document before closing). The only usage note is about the default handle, which is minimal. Lacks when-not-to-use or prerequisites.

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