docx.close

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'free resources' but does not clarify important behaviors such as whether unsaved changes are discarded, whether the docId becomes invalid, or whether close is idempotent. This is insufficient for a state-changing lifecycle operation.

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, focused sentence with no filler or redundancy. It states the core action and its purpose efficiently, making it easy to parse.

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?

Although the tool is simple, it is a lifecycle/mutation operation with no annotations, no output schema, and no side-effect transparency. The description omits critical context like data-safety implications (unsaved changes) and post-close behavior of the document handle, leaving operational gaps.

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 single parameter docId is fully documented in the schema with 'Document ID returned from docx.open', so schema coverage is 100%. The description adds no additional parameter-level meaning, so the baseline score of 3 is appropriate.

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 identifies the action ('Close') and the resource ('DOCX document'), and additionally states the purpose 'free resources'. It is unambiguous and naturally distinguishes itself from sibling tools like docx.open and docx.save.

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?

Usage is implied: call this after you are done working with an opened document to release resources. However, there is no explicit guidance on when not to call it, whether it must be called before other operations, or any alternatives.

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