A toolset for creating, editing, repairing, and reviewing Microsoft Word documents in .docx format. It covers document generation, simple edits, comments, tracked changes, conversion from Markdown, and validation.

Use it to create reports, edit existing Word files, add comments or tracked changes, convert multi-section Markdown to Word, and validate or repair .docx files.

It gives coding agents defined workflows for common Word-document tasks and checks that document files are valid. It also provides a fallback output location when a requested directory cannot be used.

docx — Skill for Claude Code and Codex by XyrusCode/ai-sync

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add XyrusCode/ai-sync --skill docx

Clone the repo

git clone --depth 1 https://github.com/XyrusCode/ai-sync

Made for: Claude Code, Codex.

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 5.1	$0.00050	$0.02080
Opus 5.5	$0.00020	$0.00832
Sonnet 5.5	$0.00010	$0.00416
Haiku 4.5	$0.00005	$0.00208

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 1mo ago.

The scan reads SKILL.md. This mod also ships 15 executable files (assets/example.js, scripts/__init__.py, scripts/docx_lib/__init__.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.

DOCX Skill

Route

Task	Route	Read
Create a new `.docx`	`docx-js` script, then `{skill_path}/scripts/docx build`	`references/docx-js.md`, then `assets/example.js`
Create native Word equations	docx-js plus literal OMML helpers	`references/docx-js.md`, `references/omml.md`
Edit text/style in an existing `.docx`	`python-docx` for simple in-place edits	`references/editing.md`
Add comments or tracked changes	`DocxContext` editing module	`references/editing.md`
Convert swarm-assembled Markdown to `.docx`	`{skill_path}/scripts/docx md2docx <file.md>`	`references/md2docx-reference.md`
Validate or repair a `.docx`	`{skill_path}/scripts/docx validate <file.docx>`	this file

Output path: write to the path the user requested. If its directory is not writable (e.g. a container path like /mnt/... that does not exist here), fall back to ./outputs/ under the current working directory, create it, and report the final path. Never fail just because a hardcoded absolute directory is missing.

When to use md2docx (gate): only for a multi-section Markdown report assembled by a swarm writing skill — i.e. there is a *.agent.final.md or several *_sec{NN}.md files produced by sub-agents, with standard Markdown footnotes ([^id] + [^id]: Title. Date. URL) for citations. For a one-off document the user asks you to write, author it natively with docx-js (the Create route); hand-authored layout is cleaner than converted Markdown.

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.

docx is a skill published in the GitHub repository XyrusCode/ai-sync (2 stars, last pushed 18d ago), licensed MIT. It adds 50 tokens to every session and 2,080 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
