- LibreOffice for PDF conversion
- Playwright for HTML rendering
Instructions
Reading Content
python -m markitdown presentation.pptx
For raw XML access:
python ooxml/scripts/unpack.py presentation.pptx output_dir
Creating New Presentations (without template)
-
Design First
- Consider subject matter, tone, audience
- Choose color palette (18 preset options available)
- Use web-safe fonts only
-
Use html2pptx Workflow
- Create HTML file for each slide (720pt × 405pt for 16:9)
- Use
<p>,<h1>-<h6>,<ul>,<ol>for text - Convert HTML to PowerPoint using html2pptx.js
-
Visual Validation
python scripts/thumbnail.py output.pptx workspace/thumbnails --cols 4
Creating from Template
- Extract text:
python -m markitdown template.pptx - Create thumbnail grid for visual analysis
- Create outline with template mapping
- Rearrange slides:
python scripts/rearrange.py template.pptx working.pptx 0,34,34,50 - Extract inventory:
python scripts/inventory.py working.pptx text-inventory.json - Generate replacement text JSON
- Apply:
python scripts/replace.py working.pptx replacement.json output.pptx
Editing Existing Presentations
- Unpack:
python ooxml/scripts/unpack.py file.pptx dir - Edit XML files
- Validate:
python ooxml/scripts/validate.py dir --original file - Pack:
python ooxml/scripts/pack.py dir output.pptx
Error Handling
- Validate after each edit before packing
- Check thumbnail grid for text cutoff/overlap
- Ensure contrast for readability
Notes
- Avoid "AI slop": excessive centered layouts, purple gradients, Inter font
- Use two-column layouts for charts/tables
- Slides are 0-indexed in scripts

Drive interactive terminal (TUI) programs — CLIs, REPLs, installers, menu apps, agent CLIs, and editors like vim — through a PTY, reading semantic screen snapshots. A pattern library classifies a screen (REPL, menu, pager, fzf search, confirm dialog, form, spinner, wizard) and drives it with a ready recipe. Use when a program expects a live terminal (arrow-key menus, prompts, spinners, password fields, curses UIs), or when a piped command hangs or prints nothing.
