Deck Forge: PowerPoint Build & Patch
Example session with this skill installed
Our agency has a client template at /workspace/acme-brand-template.pptx whose theme and layouts we must honor, plus a text outline in outline.md for the new Q4 pitch. Build the deck from the outline into a new file, acme-q4-pitch.pptx, pulling the template's actual palette and fonts instead of eyeballing them. Keep everything native and editable — no flattened images. Once generated, render each slide to images and check the contact sheet for clipped text, overlapping boxes, and low-contrast areas before you call it done.
- Read your context and instructions
- Compiled the deck forge
- Generated the UI component
Summary
Rebuilt the Q3 investor deck from a clean design contract: extracted the template's real palette and fonts, regenerated all 14 slides as native editable shapes, and verified the render with a slide contact sheet — no clipped text, no missing images.
| Metric | Before | After |
|---|---|---|
| Off-brand colors | 6 one-off hex values | theme tokens #101820 / #E58E1A |
| Text overflow slides | 4 | 0 |
| Broken image rels | 2 | 0 |
| Speaker notes coverage | 3 of 14 slides | 14 of 14 |
| Body font | Poppins (missing on Windows) | Arial, safe everywhere |
Deliverables: acme-q4-pitch.pptx plus render/grid.jpg contact sheet.
Next steps
- Review the contact sheet at render/grid.jpg and approve the title-band pattern.
- Swap the placeholder chart on slide 9 for the updated revenue PNG.
- Keep edits inside the python-pptx shapes; drop to raw OOXML only for comments and animation timing.

About this skill
The problem
Working with .pptx files programmatically is often fragile. High-level libraries struggle with complex layouts, while raw XML editing is prone to breaking the package structure.
What it does
- Extracts slide copy, speaker notes, and design tokens into structured Markdown or JSON.
- Generates editable decks using
python-pptxwith brand-aligned palettes and layouts. - Renders slides to PDF or high-resolution images for automated visual QA and layout inspection.
- Performs surgical repairs on broken presentations via raw OOXML patching of relationships and media.
- Inventories template layouts to map dynamic content to existing brand masters.
Frameworks & tools
Python, python-pptx, Playwright, LibreOffice (headless), ImageMagick, and OOXML/XML tools.
Why this beats prompting it yourself
Most LLMs treat PowerPoint as simple text blocks. This tool understands the ZIP-based anatomy of OOXML, allowing for precise control over themes, master inheritance, and relationship files that generic prompts often corrupt.
Use cases
- Automating executive report generation from raw data feeds.
- Auditing large slide libraries for brand compliance and broken assets.
- Converting technical documentation into polished, printable slide decks.
- Repairing corrupted presentations that won't open in desktop apps.
Known limitations
Requires a Python environment with specific dependencies like python-pptx and LibreOffice for rendering. Complex animations and transitions may be lost during raw XML patching.
