#What it does

The DOCX skill handles all Word document operations -- creating new documents with docx-js, editing existing ones by unpacking/repacking XML, reading and extracting content, working with tracked changes and comments, and converting between formats. It produces professional documents with proper formatting, styles, and structure.

#How to use

Activate when any .docx file is involved as input or output. This includes creating reports, memos, letters, templates, or any Word document deliverable.

#Creating New Documents

Uses docx-js (JavaScript) to generate .docx files with:

• Explicit page size (US Letter: 12240 x 15840 DXA)
• Style overrides for built-in headings with outlineLevel for TOC support
• Proper lists using LevelFormat.BULLET (never Unicode bullets)
• Tables with dual widths (columnWidths on table AND width on each cell, always DXA)
• Images with required type parameter
• Hyperlinks (external and internal with bookmarks)
• Headers/footers with page numbers
• Table of Contents using HeadingLevel only

#Editing Existing Documents

Three-step workflow:

1. Unpack: Extract XML with pretty-printing and smart quote conversion
2. Edit XML: Direct string replacement for tracked changes, comments, content modifications
3. Pack: Validate with auto-repair, condense XML, create DOCX

#Tracked Changes

Supports insertions, deletions, rejecting another author's changes, and restoring deleted content -- all with proper XML structure and formatting preservation.
