SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires markitdown[pptx], Pillow, pptxgenjs, LibreOffice (soffice), poppler (pdftoppm), and includes scripts (resource) components.

What problem does it solve?

This Skill removes the guesswork of working with PowerPoint files by providing a repeatable workflow to extract content, edit slide decks, and catch visual/content issues before you ship.

Core Features & Use Cases

  • Extract and analyze .pptx content (text extraction, raw XML inspection).
    • Use case: Pull the exact text from a deck so you can rewrite sections or generate a summary.
  • Template-driven slide editing (unpack → edit slide XML → clean → repack).
    • Use case: Update a pitch deck to match a new campaign while preserving layouts and speaker notes.
  • Create decks from scratch when no template exists.
    • Use case: Generate a brand-new presentation structure using programmatic slide creation guidance.
  • Visual QA loop to detect layout defects (overflow, overlaps, placeholder leftovers) by converting slides to images and iterating fixes.
    • Use case: After editing, automatically render slides to images and inspect each slide for typography and spacing problems.
