PPTX Creation, Editing & Analysis

A complete PowerPoint skill that lets Claude build, edit, read, and QA .pptx/.potx decks reliably.

What it does

  • Creates decks via pptxgenjs scripts, with a curated list of ~20 footguns that silently corrupt files (hex colors with #, negative shadow offsets, outEnd labels on stacked charts, combo charts missing axis declarations).
  • Edits existing decks and templates by unzipping the package, editing ppt/slides/slideN.xml, and repacking — with helper scripts to duplicate slides (add_slide.py) and prune orphaned parts (clean.py).
  • Reads content with markitdown (per-slide text dump) and thumbnail.py (labeled grid of every slide for picking template layouts).
  • Enforces QA: validate.py checks schema, relationships, content types and charts; a grep pass catches leftover placeholder text; PDF→JPEG rendering drives a visual checklist for overflow, overlap, and margins.
  • Design guidance: ten topic-driven color palettes, a QA-safe font list, size hierarchy, and an explicit "avoid" list (no AI-looking accent bars or underlines).

Who it's for

  • Consultants, founders, and PMs who build pitch decks and reports
  • Teams that need corporate .potx templates filled in automatically
  • Anyone extracting slide text for summaries, emails, or docs
  • Developers automating slide generation pipelines

Examples

  1. "Turn this market research into a 12-slide investor deck" → pick a palette → generate the pptxgenjs script → run validate.py → render slides and fix overflow.
  2. "Fill our company.potx layout 3 with the Q3 numbers" → thumbnail the template → duplicate slides → replace XML text → validate with --original.
  3. "Summarize kickoff.pptx into an email" → markitdown extracts slide-by-slide text for the summary.
