PPTX Skill

Choosing an approach

Extract text or data	`python -m markitdown presentation.pptx`	Also: `slides.py thumbnail` for visual grid
Modify an existing file or template	Unpack to XML, edit, repack	See EDITING.md
Generate a deck from scratch	JavaScript with `pptxgenjs`	See CREATING.md

Pre-installed sandbox packages: markitdown[pptx], Pillow, pptxgenjs (Node), react-icons + react + react-dom + sharp (icon rendering), LibreOffice (soffice), Poppler (pdftoppm).

Math and Equations

Render equations with Unicode math symbols only. Do not use OMML or generate equation images — LibreOffice cannot display either during visual QA.
