PPTX Skill

Create professional PowerPoint presentations using pptxgenjs in the OpenWork environment.

---

Environment Prerequisites (CRITICAL)

OpenWork runs a non-interactive shell that does NOT load ~/.zshrc. Global npm packages are installed but NODE_PATH is not set. You MUST prefix every node command with NODE_PATH:

NODE_PATH=$(npm root -g) node script.js

Without this prefix, require('pptxgenjs') will fail with MODULE_NOT_FOUND.

Verify Setup

# Check pptxgenjs is installed globally
npm list -g pptxgenjs

# Test it can be loaded
NODE_PATH=$(npm root -g) node -e "const p = require('pptxgenjs'); console.log('pptxgenjs OK')"

If not installed, run: npm install -g pptxgenjs

Additional Dependencies (optional)

npm install -g react-icons react react-dom sharp   # For icons
pip install "markitdown[pptx]"                      # For reading existing .pptx
pip install Pillow                                  # For thumbnails

Quick Start

Write a .js script, then execute with NODE_PATH:

NODE_PATH=$(npm root -g) node generate_ppt.js

Minimal Example

const pptxgen = require("pptxgenjs");

let pres = new pptxgen();
pres.layout = "LAYOUT_16x9";
pres.author = "Jansen";

let slide = pres.addSlide();
slide.background = { color: "1E2761" };
slide.addText("Hello World", {
  x: 1, y: 2, w: 8, h: 1.5,
  fontSize: 44, fontFace: "Arial",
  color: "FFFFFF", bold: true, align: "center"
});

pres.writeFile({ fileName: "output.pptx" });

Design Guidelines

Before Starting

• Pick a bold, content-informed color palette: The palette should feel designed for THIS topic.
• Dominance over equality: One color should dominate (60-70%), with 1-2 supporting tones and one accent.
• Dark/light contrast: Dark backgrounds for title + conclusion slides, light for content.
• Commit to a visual motif: Pick ONE distinctive element and repeat it across every slide.
