What it does

Creates decks with pptxgenjs, front-loading ~20 real-world footguns that silently corrupt files (hex colors without #, negative shadow offsets, stacked-bar label positions, combo-chart axis declarations, and more).
Edits existing decks and templates by unzipping the package, editing ppt/slides/slideN.xml, and repacking — with helper scripts for slide duplication (add_slide.py) and orphan cleanup (clean.py).
Reads content via markitdown per-slide text dumps and thumbnail.py labeled slide grids for picking template layouts.
Guides design with 10 curated color palettes, a QA-safe font list, type-size and spacing rules, and an explicit "avoid" list (no accent stripes, no underlines beneath titles, no text-only slides).
Enforces QA: schema/relationship/chart validation plus PDF→JPEG rendering so overflow, overlap, and contrast defects get caught before delivery.

Who it's for

Consultants, founders, and PMs who build pitch decks and reports regularly
Teams filling corporate .potx templates over and over
Anyone extracting text from old presentations for summaries or emails
Developers automating slide generation pipelines

Example uses

"Turn this business plan into a 12-slide investor deck" → picks a palette, generates with pptxgenjs, validates, renders images, fixes defects.
"Fill our company template.potx with this quarter's numbers" → thumbnails the template, duplicates layouts, edits XML, validates with --original.
"Summarize last year's three decks into one email" → markitdown extracts slide-by-slide text for synthesis.
