What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

name: docx
description: "Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files) or Word templates (.dotx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', '.dotx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx or .dotx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation."

# DOCX creation, editing, and analysis

A `.docx` is a ZIP archive of XML files. Choose your approach by task:

| 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` |

> Script paths below are relative to this skill's directory.

## Creating with docx-js — gotchas

`docx` is preinstalled — do not run `npm install` first; write the script and `require('docx')` directly. Only if that require fails: `npm install docx`. The model knows the API; these are the footguns:

- **Page size defaults to A4.** For US Letter set `page: { size: { width: 12240, height: 15840 } }` (DXA; 1440 = 1′′).
- **Landscape:** pass portrait dimensions and `orientation: PageOrientation.LANDSCAPE` — docx-js swaps width/height internally.
- **Tables need dual widths:** set `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.
- **Table shading:** use `ShadingType.CLEAR`, never `SOLID` (renders black).
- **Lists:** never insert `•` literally; use a `numbering` config with `LevelFormat.BULLET`.
- **`ImageRun` requires `type:`** (`"png"`, `"jpg"`, ...).
- **`PageBreak` must be inside a `Paragraph`.**
- **Never use `\n`** — use separate `Paragraph` elements.
- **TOC:** headings must use built-in `HeadingLevel.*`; custom heading styles need `outlineLevel` set or they won't appear.
- **Don't use a table as a horizontal rule** — use a paragraph bottom border instead.
- **Dot-leader / right-aligned-on-same-line:** use `PositionalTab` (`alignment: PositionalTabAlignment.RIGHT`, `leader: PositionalTabLeader.DOT`) inside a `TextRun`, not literal `.` or space padding.

## Verify the output

After writing a `.docx`, render it and look at it:

```bash
python scripts/office/soffice.py --headless --convert-to pdf output.docx
pdftoppm -jpeg -r 100 output.pdf page
ls page-*.jpg   # then Read the images
```

`pdftoppm` zero-pads page numbers to the width of the page count (`page-01.jpg`...`page-12.jpg`).

## Editing existing documents

Legacy `.doc` files must be converted first: `python scripts/office/soffice.py --headless --convert-to docx file.doc`.

```bash
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

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:

Questions

What does the Docx skill do?

Battle-tested Claude Code, OpenAI Codex, Cursor configs, plugins, hooks and agents with Kimi, MiniMax and GLM API support.

Is Docx safe to install?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.

What can Docx access on my machine?

The audit observed no filesystem, network or shell use at all in its source.

What do I need installed to use Docx?

Its own instructions reference width. Dependencies are pinned to exact versions.

How current is this page?

The grade is for one exact copy of the source (ae618ef5da66), read on 2026-10-12. The repository is watched, and a new audit runs when it changes — this is the first audit.
