DOCX

Why you would use it

DOCX is for Word editing, structured revision, and document cleanup. Work with Word documents, structured edits, and document revisions before export.

You would use it when the task is already clear, but you do not want to design the workflow, prompt structure, or tool wiring from scratch. A good skill gives you a pre-shaped execution path and cuts down trial and error.

The practical check is simple: does the task match, does the output match, and does your current stack fit the implementation style used in Anthropic. If those line up, the source folder is worth opening.
