Overview

This is a Slides Skill toolkit designed for AI Agents, enabling AI to generate real, editable .pptx PowerPoint files instead of HTML web presentations.

Built on PptxGenJS, it includes complete layout helpers, rendering validation scripts, and best-practice workflows.

Core Features

• Generate native PowerPoint files that open in Office/WPS/Keynote
• Preserve full editability of text, charts, and images
• Support multiple slide sizes (16:9, 4:3, etc.)

🛠️ Complete Toolchain

• Layout Helpers: pptxgenjs_helpers/ provides auto text box sizing, image cropping, LaTeX formulas, code highlighting
• Render Validation: render_slides.py converts PPTX to PNG previews
• Overflow Detection: slides_test.py automatically detects content exceeding slide boundaries
• Font Detection: detect_font.py reports missing or substituted fonts

📐 Smart Layout

• Automatic text box sizing (autoFontSize, calcTextBox)
• Intelligent image cropping and scaling (imageSizingCrop, imageSizingContain)
• Overlap and out-of-bounds warning system

🎨 Rich Content Support

• Native PowerPoint charts (bar, line, pie, etc.)
• LaTeX math formula rendering
• Syntax-highlighted code blocks
• SVG vector graphics embedding
