SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires defusedxml, lxml, Pillow, and includes scripts (resource) components.

What problem does it solve?

Working with .pptx slide decks manually forces you to juggle text extraction, layout tinkering, and validation across disconnected tools, which slows delivery and leaves styling problems unresolved.

Core Features & Use Cases

  • Guided content inspection: Use markitdown extraction plus thumbnail scripts to read, parse, and sanity-check the text and layout before touching slides.
  • Template-driven editing: Follow the editing workflow with unpack/clean/pack tools, slide duplication helpers, and thumbnail previews to update templates or restructure slide sequences.
  • Creation and design coaching: Rely on the pptxgenjs guidance, curated color palettes, typography rules, and the QA loop (visual checks, conversion scripts, subagents) to craft brand-ready decks from scratch or adapt templates for board and investor pitches.

Quick Start

First run python -m markitdown on the .pptx file to inspect the text before using the pptx skill to edit or generate the slides.
