PPTX Creation, Editing & Analysis

Official

The official Anthropic skill for building slide decks with pptxgenjs, editing .pptx/.potx templates at the XML level, extracting content, and running required file and visual QA.

What it does

  • Creates decks with pptxgenjs, front-loading the footguns that silently corrupt files: #-prefixed or 8-digit hex colors, negative shadow offsets, outEnd labels on stacked charts, secondary axes missing valAxes/catAxes, reused option objects.
  • Edits existing decks and templates via unzip → edit ppt/slides/slideN.xml → rezip, with helper scripts for safe slide duplication (add_slide.py) and orphan cleanup (clean.py).
  • Reads content with markitdown (per-slide text blocks) and thumbnail.py (labeled grid for picking template layouts).
  • Design guidance: 10 curated palettes, layout patterns, QA-safe font list, type scale, and an explicit "avoid" list (no accent stripes, no underlines beneath titles, no text-only slides).
  • Mandatory QA: validate.py for schema/relationship/chart checks (--original when template-derived) plus a PDF → JPG render loop to catch overflow, overlap, and margin issues.

Who it's for

  • Consultants and analysts turning documents into presentation decks
  • Teams that must fill corporate .potx templates without breaking them
  • Developers batch-parsing, converting, or generating PowerPoint files

Examples

  1. "Turn this market research summary into a 12-slide pitch deck" — picks a palette, writes a pptxgenjs script, validates, then reviews rendered slides for overflow.
  2. "Build the quarterly review using layout 3 from template.potx" — thumbnails the template, duplicates slides with add_slide.py, edits XML, validates with --original.
  3. "Pull the speaker notes and body text out of deck.pptx for an email recap" — runs markitdown and summarizes slide by slide.
