SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill removes the friction of working directly with PowerPoint XML when you need to read, edit, create, or validate .pptx files. It helps you turn complex presentation tasks into a predictable workflow instead of manual slide-by-slide editing.

Core Features & Use Cases

  • Read and inspect decks: Extract slide content, preview layouts with thumbnails, and verify structure before making changes.
  • Edit and build presentations: Update existing slides, duplicate layouts, create decks from templates, and generate new presentations from scratch.
  • Validate and repair: Check XML well-formedness, relationships, content types, IDs, tracked changes, and other issues that can corrupt a deck.
  • Use Case: A consultant receives a client presentation and needs to update several slides, preserve formatting, and confirm the file still opens cleanly. This Skill can unpack the deck, edit the content safely, validate the result, and repack it into a working .pptx.

Quick Start

Use the pptx skill to inspect the attached presentation, update the requested slides, and return a validated .pptx file.
