Overview
What it does
New decks are written with pptxgenjs; existing decks and templates are edited directly in their slide XML, with scripts to duplicate slides and clean up the package. The skill carries its own design guidance: colour palettes, type sizes, spacing, and a list of common mistakes to avoid.
What sets it apart is the quality-assurance step. The instructions make Claude convert the finished deck to images and inspect every slide for overflowing text, overlaps and contrast problems before calling the job done, and they treat that check as mandatory rather than optional.
Triggers
When Claude uses it
- Any task involving a .pptx or .potx file, as input or output.

What it needs
- Node.js with pptxgenjs; Python with markitdown, Pillow, defusedxml and lxml; LibreOffice and Poppler for rendering.
- Proprietary licence: use it through Claude or the official plugin only.
