SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires markitdown, Pillow, pptxgenjs, LibreOffice, poppler-utils, defusedxml, PptxGenJS, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill solves the problem of manually struggling with PowerPoint (.pptx) files—extracting their contents, updating slide layouts, and generating reliable outputs without corrupting the underlying OOXML structure.

Core Features & Use Cases

Extract text and inspect slide structure: Convert PPTX content to readable form for downstream use (including QA checks and placeholder detection).
Edit presentations safely: Use a template-based workflow by analyzing, unpacking, modifying slide XML, and repacking to produce a valid .pptx.
Create decks from scratch: Generate a new slide deck using code when no template/reference exists.
Visual QA loop: Convert slides to images for “bug-hunt” inspection of layout issues like overflow, spacing, and contrast.

Quick Start

Use the pptx skill to extract and review the text from the attached file 'deck.pptx' so you can prepare accurate slide edits.
