Codex Doc Renderer

TL;DR

Render documentation to DOCX format via render_docx.py. Specialized utility, activate only when DOCX export is explicitly requested.

DOCX Skill

Activation

1. Activate when the task involves reading, creating, or editing .docx documents.
2. Activate on explicit $codex-doc-renderer or $docx.

When to use

• Read or review DOCX content where layout matters (tables, diagrams, pagination).
• Create or edit DOCX files with professional formatting.
• Validate visual layout before delivery.

Workflow

1. Prefer visual review (layout, tables, diagrams).
   • If soffice and pdftoppm are available, convert DOCX -> PDF -> PNGs.
   • Or use scripts/render_docx.py (requires pdf2image and Poppler).
   • If these tools are missing, install them or ask the user to review rendered pages locally.
2. Use python-docx for edits and structured creation (headings, styles, tables, lists).
3. After each meaningful change, re-render and inspect the pages.
4. If visual review is not possible, extract text with python-docx as a fallback and call out layout risk.
5. Keep intermediate outputs organized and clean up after final approval.

Temp and output conventions

• Use tmp/docs/ for intermediate files; delete when done.
• Write final artifacts under output/doc/ when working in this repo.
• Keep filenames stable and descriptive.

Dependencies (install if missing)

Prefer uv for dependency management.

Python packages:

uv pip install python-docx pdf2image

If uv is unavailable:

python3 -m pip install python-docx pdf2image

System tools (for rendering):

# macOS (Homebrew)
brew install libreoffice poppler

# Ubuntu/Debian
sudo apt-get install -y libreoffice poppler-utils

If installation isn't possible in this environment, tell the user which dependency is missing and how to install it locally.

Environment

No required environment variables.

Rendering commands

DOCX -> PDF:

soffice -env:UserInstallation=file:///tmp/lo_profile_$$ --headless --convert-to pdf --outdir $OUTDIR $INPUT_DOCX

PDF -> PNGs:

pdftoppm -png $OUTDIR/$BASENAME.pdf $OUTDIR/$BASENAME

Bundled helper:

python scripts/render_docx.py /path/to/file.docx --output_dir /tmp/docx_pages

Quality expectations

• Deliver a client-ready document: consistent typography, spacing, margins, and clear hierarchy.
• Avoid formatting defects: clipped/overlapping text, broken tables, unreadable characters, or default-template styling.
• Charts, tables, and visuals must be legible in rendered pages with correct alignment.
• Use ASCII hyphens only. Avoid U+2011 (non-breaking hyphen) and other Unicode dashes.
• Citations and references must be human-readable; never leave tool tokens or placeholder strings.

Final checks

• Re-render and inspect every page at 100% zoom before final delivery.
• Fix any spacing, alignment, or pagination issues and repeat the render loop.
• Confirm there are no leftovers (temp files, duplicate renders) unless the user asks to keep them.
