Most developers don’t think of Word document generation as a coding problem — until they have to produce one programmatically. Maybe it’s a contract template that needs to be populated from a database. Maybe it’s a weekly report that gets emailed to stakeholders. Maybe it’s a client-facing deliverable that needs to look like it was formatted by a human, not exported from a script. When that moment arrives, the usual tools — python-docx, docxtemplater, mammoth — all have their quirks, and figuring out which one to use, let alone the correct API calls, eats up time you don’t have.
The docx Claude Code skill solves this. It gives Claude the specific knowledge needed to produce professional Word documents correctly — the right libraries, the right patterns for styles and tables and images, and the hard-won understanding of where the common mistakes live. Instead of reading the python-docx docs and trial-erroring your way through paragraph formatting, you describe what you want and Claude generates working code.
What the docx Skill Covers
The skill encodes a set of best practices that go beyond what you’d find in a library’s README. It covers which library to use for which task (python-docx for generation from scratch; mammoth for HTML-to-docx conversion; docxtemplater when you’re working from a template), and it handles the formatting details that trip people up: paragraph spacing, heading hierarchies, table cell padding, image anchoring, header and footer content, and page numbering.
It also covers the output side — ensuring generated files land in the right place, are valid .docx files that open correctly in Microsoft Word and LibreOffice, and don’t silently corrupt styles by mixing incompatible formatting approaches.
Installing the Skill
Skills live in your project’s skills folder and are referenced from your CLAUDE.md. To add the docx skill:
# From your project root
mkdir -p .claude/skills
# Copy or create the skill file
touch .claude/skills/docx/SKILL.mdThen in your CLAUDE.md, reference it:
## Skills
- .claude/skills/docx/SKILL.md — Use when creating or editing Word (.docx) documentsThe skill file itself contains instructions that Claude reads before generating any document-related code. You can find the community skill library on GitHub for ready-to-use versions, or write your own based on the patterns your projects use.
Example Workflow
Here’s a realistic example: generating a client report from structured data.
You have a JSON file with monthly metrics — page views, signups, conversion rates — and you need to produce a Word document with a cover page, a summary table, and a section for each month with a narrative paragraph. Without the skill, you’d spend twenty minutes finding the right python-docx calls for table formatting alone. With it:
Generate a Word document from metrics.json.
The document should have:
- A cover page with the client name and reporting period
- A summary table showing all months side by side
- One section per month with a brief narrative paragraph
- Page numbers in the footer
- Our standard heading styles (Heading 1 for months, Heading 2 for subsections)
Save to output/monthly-report.docxClaude reads the docx skill, understands the constraints (correct library, style approach, output path), and generates the full script. The result is a properly structured .docx file with real styles — not hardcoded font sizes — that you can hand to a client.
What the Skill Prevents
A few things go wrong consistently when generating Word documents without guidance:
Style pollution. If you set font sizes directly on paragraphs rather than using named styles, the document looks fine until someone opens it in Word and the Style Gallery is full of custom inline formatting. The skill enforces style-based formatting throughout.
Table cell spacing. python-docx’s default table formatting doesn’t match Word’s defaults. The skill applies correct cell margins and border widths so tables look right without manual adjustment.
Image anchoring. Inserting images inline versus as floating objects behaves very differently in Word. The skill specifies the correct approach based on context and avoids the layout issues that floating images cause in paginated documents.
Corrupt output. It’s possible to generate a .docx file that opens in some applications but fails Word’s validation. The skill ensures that the XML structure underneath is valid and that the file will open correctly everywhere.
When to Use It
The docx skill is worth reaching for any time you need to produce a Word document as part of an automated workflow. Report generation, contract population, proposal templates, letter mail merges, test result exports — wherever a human would otherwise open Word and fill in a template manually, this skill lets Claude automate it properly.
It pairs naturally with the pdf skill if your workflow ends with converting the Word document to PDF for distribution, and with the xlsx skill if you’re pulling structured data from a spreadsheet before building the document.

Document generation is one of those tasks that looks simple until you’re in it. The docx skill removes the friction by giving Claude the specific knowledge to do it right — correct library choices, correct formatting patterns, correct output. You describe the document you need, and Claude produces code that actually works.
