A set of instructions for creating, reading, editing, and formatting Microsoft Word files, including `.docx` documents and `.dotx` templates. It explains which tools and methods to use for each kind of document work.

Use it to create Word documents, inspect their content, modify existing files, work with templates, or add elements such as tables of contents and headings.

It reduces mistakes caused by treating Word files like ordinary text files, especially when preserving formatting or editing existing documents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00184	$0.01762
Opus 5	$0.00092	$0.00881
Sonnet 5	$0.00037	$0.00352
Haiku 4.5	$0.00018	$0.00176

Security

Grade A, and why

docx scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 15 executable files (scripts/__init__.py, scripts/accept_changes.py, scripts/comment.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This is a copy

95% identical to docx — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:

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

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
