Create, read, and edit Word documents — reports, memos, letters, letterheads, tables of contents, tracked changes (redlining), and comments. A .docx is a ZIP archive of XML files; this skill covers both the high-level creation path and surgical XML editing.
Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx) or Word templates (.dotx). Triggers include: any mention of "Word doc", ".docx", ".dotx", or requests for a "report", "memo", "letter", or similar deliverable as a Word file; extracting or reorganizing content from .docx files; find-and-replace in Word files; inserting images; tracked changes or comments. Do NOT use for PDFs (see the pdf skill), spreadsheets (xlsx), or presentations (powerpoint).
npm ls docx --depth=0 2>/dev/null | grep -q docx || npm install docx # creation (docx-js)
pip show pandoc >/dev/null 2>&1 || true; which pandoc || sudo apt install -y pandoc # reading
which soffice || sudo apt install -y libreoffice # rendering/verification
which pdftoppm || sudo apt install -y poppler-utils # PDF → images
pip install defusedxml lxml # validation scripts
macOS: brew install pandoc libreoffice poppler.
| Task | Approach |
|---|---|
| Create a new document | Write a docx (npm) script — see gotchas below |
| Edit an existing document | unzip → edit word/document.xml → zip (docx-js cannot open existing files) |
| Read content | pandoc -t markdown file.docx (or read_file, which auto-extracts .docx text) |
Script paths below are relative to this skill's directory.
Write the script and require('docx'). The model knows the API; these are the footguns:
page: { size: { width: 12240, height: 15840 } } (DXA; 1440 = 1″).orientation: PageOrientation.LANDSCAPE — docx-js swaps width/height internally.columnWidths on the table AND width on every cell, both in WidthType.DXA (PERCENTAGE breaks in Google Docs). Column widths must sum to the table width.ShadingType.CLEAR, never SOLID (renders black).• literally; use a numbering config with LevelFormat.BULLET.ImageRun requires type: ("png", "jpg", …).PageBreak must be inside a Paragraph.\n — use separate Paragraph elements.HeadingLevel.*; custom heading styles need outlineLevel set or they won't appear.PositionalTab (alignment: PositionalTabAlignment.RIGHT, leader: PositionalTabLeader.DOT) inside a TextRun, not literal . or space padding.After writing a .docx, render it and look at it:
python scripts/office/soffice.py --headless --convert-to pdf output.docx
pdftoppm -jpeg -r 100 output.pdf page
ls page-*.jpg # then inspect each with vision_analyze
pdftoppm zero-pads page numbers to the width of the page count (page-01.jpg…page-12.jpg).
Legacy .doc files must be converted first: python scripts/office/soffice.py --headless --convert-to docx file.doc.
unzip -q doc.docx -d unpacked/
find unpacked -type l -delete # strip symlink entries — docx from external parties is untrusted
python scripts/merge_runs.py unpacked/ # coalesce fragmented runs so text is findable
# edit unpacked/word/document.xml in place — do NOT reformat or pretty-print
(cd unpacked && rm -f ../out.docx && zip -Xr ../out.docx .)
python scripts/office/validate.py out.docx --original doc.docx # XSD checks; --auto-repair fixes common issues
# redlining? add --author "<the name you redlined under>" to check every edit is tracked
Word splits text across many <w:r> runs (revision ids, spell-check markers), so a phrase you can see in the document often doesn't exist as a contiguous string in the XML. merge_runs.py merges adjacent identically-formatted runs in word/document.xml without changing content or rendering; it also accepts a .docx directly (python scripts/merge_runs.py doc.docx -o merged.docx).
Tracked changes: when redlining, validate with --author "<the name you redlined under>" (needs --original) — it reports any text you changed without a <w:ins>/<w:del> around it, which is easy to do by accident and invisible in the accepted view. Wrap runs in <w:ins>/<w:del> with w:id, w:author, w:date attributes. Inside <w:del>, the text element is <w:delText>, not <w:t>. A deleted paragraph mark (<w:pPr><w:rPr><w:del w:id=".." w:author=".." w:date=".."/></w:rPr></w:pPr>) means "merge this paragraph into the next" — so deleting a paragraph outright is that plus a <w:del> around every run. The <w:del/> must come before the rPr's other children; their order is schema-enforced.
To produce a clean copy with all tracked changes accepted: python scripts/accept_changes.py in.docx out.docx.
Accepting a deleted paragraph mark should join that paragraph to the one below it, so a paragraph whose runs are all deleted vanishes. Word does this; accept_changes.py and pandoc --track-changes=accept don't always. Both fail the same way — they strip the deleted text but leave the emptied paragraph behind, which reads as a stray empty bullet when it was auto-numbered:
pandoc --track-changes=accept never joins the paragraphs.accept_changes.py (LibreOffice) joins them correctly, except when the deleted paragraph is followed by an empty spacer paragraph.An empty bullet in either view is an artifact of that view, not a defect in the document. Check paragraph deletions in the XML.
Comments require six cross-linked files. Use the helper — directory mode when you'll also be editing document.xml (saves an unzip/rezip cycle), .docx-direct mode otherwise:
# Against an already-unpacked directory (preferred when also placing markers)
python scripts/comment.py unpacked/ "Fees & expenses cap is too low"
python scripts/comment.py unpacked/ "Agreed" --parent 0
# Against a .docx directly
python scripts/comment.py contract.docx "This cap is too low" -o annotated.docx
The script writes comments.xml, commentsExtended.xml, commentsIds.xml, commentsExtensible.xml, the relationships, and the content-type overrides. Comment IDs are auto-assigned. It then prints the <w:commentRangeStart>/<w:commentRangeEnd>/<w:commentReference> snippet to add to word/document.xml so the comment anchors to specific text — until you place those markers, the comment exists but is not visible.
xml.etree.ElementTree — it rewrites namespace prefixes and corrupts the file. Use defusedxml.minidom for scripted transforms.cd unpacked && zip -Xr ../out.docx .) and rm the target first, or deleted parts survive in the archive.python scripts/office/validate.py out.docx --original in.docx — schema, relationship, and content-type checks; every failure names its fix.vision_analyze — look for broken tables, missing images, spacing artifacts, leftover placeholder text.pdf (PDF work), xlsx (spreadsheets), powerpoint (decks), ocr-and-documents (scanned input extraction).
