"Builds docxtpl templates, DOCX extraction for RAG, and EAA accessibility checks. Use when templating Word or extracting tables; plain edits and redlines: official docx skill."

Document DOCX Skill - Quick Reference

This skill covers the specialist .docx lanes: docxtpl template pipelines, python-docx structural edits and extraction, LLM/RAG ingestion, and accessibility/EAA compliance.

Boundary: when the official Anthropic docx skill is available, prefer it for plain create/edit (docx-js), tracked-change (redline) authoring via <w:ins>/<w:del> with validate.py, and comment authoring. When the user asks for "a document" without naming a format and a document connector or artifact type is available, prefer that over generating a .docx.

Core Decision Rules

  • Non-developers own the layout in Word, and code supplies data: docxtpl. Code decides the structure: python-docx (Python) or docx (Node).
  • Render templates fail-closed. docxtpl's defaults render a missing variable as blank and insert &/< unescaped, so the file opens fine and passes a tag scan. Use scripts/docx_render_template.py (StrictUndefined + autoescape); see references/template-workflows.md.
  • Tracked changes: never promise high-level library support, and never fake redlines with colour or strikethrough. Route authoring to the official docx skill's OOXML workflow. See references/tracked-changes.md.
  • Semantic HTML from a trusted file: mammoth, then sanitise (it does no sanitisation). Markdown/JSON for RAG: a Markdown converter or scripts/docx_extract.py; see references/llm-extraction-workflows.md.
  • DOCX feeding a KB or index: tables inside content controls are silently missing from Document.tables, tables pasted as images have no text, tracked changes need an explicit accept/original policy, and filenames can lie. Run the table-count detection check in references/docx-extraction-failure-modes.md before indexing any file (load it whenever DOCX is ingestion input).
  • PDF output: Word automation for the highest fidelity; LibreOffice headless for CI and batch.
  • .doc: convert to .docx first. .docm/.dotm: treat the macros as untrusted and never execute them.
  • .docx is the editable source; PDF is the release artifact.

Quick Reference

| Task | Tool | When | |------|------|------| | Template fill, mail merge | docxtpl + scripts/docx_render_template.py | Word-authored templates, batch documents | | Structural edits in Python | python-docx (references/docx-patterns.md) | Styles, tables, sections, fields, hyperlinks | | Comments | python-docx add_comment (version-gated) or the official docx skill | Review notes without revisions | | DOCX to HTML | mammoth via scripts/docx_to_html.mjs | Trusted documents, semantic HTML | | DOCX to JSON/Markdown | scripts/docx_extract.py, Markdown converters | Automation, RAG ingestion | | Inspect revisions/comments | scripts/docx_inspect_ooxml.py | Before editing any reviewed document | | Release gate | scripts/docx_quality_gate.py | Every generated or edited file | | DOCX to PDF | Word automation / LibreOffice headless | Release artifacts, CI smoke tests |

Format And Safety Caveats

  • python-docx comments: main body only, no anchors in headers or footers, no threaded replies or resolved state, and anchors are whole runs.
  • python-docx has no tracked-change authoring, no alt-text property, no field API and no public hyperlink authoring API. The workarounds in the references use private attributes; re-verify them after upgrades.
  • A TOC and other Word fields stay empty or stale until updated in Word or rendered by LibreOffice.
  • New python-docx documents can inherit author, date and comments from the default template. Inspect core properties before distribution.

Version-Gate Before Promising A Feature

Do not assume the environment has a current library:

  • Document.add_comment() is a recent python-docx addition and raises AttributeError on older pins. Check hasattr(docx.document.Document, "add_comment") before promising comment support.
  • If a user asks for something flagged unsupported here (tracked-change authoring in python-docx, threaded replies, resolved comments), say so plainly and route to the official docx skill. Do not approximate it with formatting.

Default Workflow

  1. Identify the file type and trust level: .docx/.dotx, .docm/.dotm, or legacy .doc.
  2. If the document may carry review metadata, run scripts/docx_inspect_ooxml.py --json first.
  3. Generate or modify: docxtpl through docx_render_template.py, or python-docx/docx for structure.
  4. For a newly generated output, set doc.core_properties to the intended author, clear template comments, and set created/modified to datetime.now(timezone.utc).replace(tzinfo=None) (python-docx expects naive UTC). For edits to an existing file, preserve provenance unless the user requested a metadata reset.
  5. Run scripts/docx_quality_gate.py. It exits 2 on any issue, including a requested --check-libreoffice that could not run.
  6. Render to images and look at every page before shipping: soffice --headless --convert-to pdf out.docx && pdftoppm -png -r 80 out.pdf page, then open the page-*.png files. For external distribution, also check in Word and apply the accessibility checklist.
python3 scripts/docx_render_template.py template.docx context.json out.docx   # exit 2 on missing vars
python3 scripts/docx_quality_gate.py out.docx --json                          # exit 2 on any issue
python3 scripts/docx_extract.py in.docx --include headers footers comments --out extracted.json
node scripts/docx_to_html.mjs in.docx out.html --style-map map.txt --extract-images-dir assets/

Round-Trip Release Proof

  • Capture the expected counts of sections, tables, images, hyperlinks, comments and tracked changes before the final save.
  • Reopen the saved DOCX and compare the counts.
  • Render a copy and inspect page breaks, numbering, table overflow, missing fonts and unresolved tags.

A successful OOXML parse or text extraction does not prove layout fidelity. A visually correct PDF does not prove that comments, hyperlinks, fields or accessibility metadata survived in the editable DOCX. Record which viewer did the primary review and which secondary viewer was checked.

Learnings Loop

When prior decisions or pitfalls are relevant, consult learnings.consolidated.md if present; use learnings.md only for needed history or as the available fallback. Otherwise skip both.

After applying it, if you encountered a pattern worth remembering, a mistake worth preventing, or a domain fact that surprised you, append one dated bullet to learnings.md via agents-skills-feedback-loop/scripts/append_learning.py. Do not modify SKILL.md itself.
