+---
+
+# PptxGenJS Slide Making Skill
+
+This skill teaches how to generate native .pptx slides using PptxGenJS (JavaScript).
+
+## PptxGenJS Reference
+
+**Read [pptxgenjs.md](pptxgenjs.md) for the complete PptxGenJS API reference**, including:
+- Setup & basic structure
+- Text & formatting
+- Lists & bullets
+- Shapes & shadows
+- Images & icons
+- Slide backgrounds
+- Tables & charts
+
+---
+
+## Font Rules
+
+### Font Family Standards
+
+| Language | Default | Alternatives |
+|----------|---------|--------------|
+| **Chinese** | Microsoft YaHei (微软雅黑) | — |
+| **English** | Arial | Georgia, Calibri, Cambria, Trebuchet MS |
+
+```javascript
+fontFace: "Microsoft YaHei"  // Chinese text
+fontFace: "Arial"            // English text (or approved alternative)
+```
+
+Use system-safe fonts for cross-platform compatibility. Header/body can use different fonts (e.g., Georgia + Calibri).
+
+### No Bold for Body Text
+
+**Plain body text and caption/legend text must NOT use bold.**
+
+- Body paragraphs, descriptions → normal weight
+- Captions, legends, footnotes → normal weight
+- Reserve bold for titles and headings only
+
+```javascript
+// ✅ Correct
+slide.addText("Main Title", { bold: true, fontSize: 36, fontFace: "Arial" });
+slide.addText("Body text here.", { bold: false, fontSize: 14, fontFace: "Arial" });
+
+// ❌ Wrong
+slide.addText("Body text here.", { bold: true, fontSize: 14 });
+```
+
+---
+
+## Color Palette Rules (MANDATORY)
+
+### Strict Palette Adherence
+
+**Use ONLY the provided color palette. Do NOT create or modify colors.**
+
+- All colors must come from the user-provided palette
+- Do NOT use colors outside the palette
+- Do NOT modify palette colors (brightness, saturation, mixing)
+- **Only exception**: Add transparency using the `transparency` property (0-100)
+
+```javascript
+// ✅ Correct: Using palette colors
+slide.addShape(pres.shapes.RECTANGLE, { fill: { color: theme.primary } });
+slide.addText("Title", { color: theme.accent });
+
+// ❌ Wrong: Colors outside palette
+slide.addShape(pres.shapes.RECTANGLE, { fill: { color: "1a1a2e" } });
+```
+
+### No Gradients
+
+**Gradients are prohibited. Use solid colors only.**
+
+```javascript
+// ✅ Correct: Solid colors
+slide.background = { color: theme.bg };
+
+// ✅ Correct: Solid + transparency for overlay
+slide.addShape(pres.shapes.RECTANGLE, { fill: { color: theme.accent, transparency: 50 } });
+```
+
+### No Animations
+
+**Animations and transitions are prohibited.** All slides must be static.
+
+---
+
+## Page Number Badge (REQUIRED)
+
+All slides **except Cover Page** MUST include a page number badge in the bottom-right corner.
+
+- **Position**: x: 9.3", y: 5.1"
+- Show current number only (e.g. `3` or `03`), NOT "3/12"
+- Use palette colors, keep subtle
+
+### Circle Badge (Default)
+
+```javascript
+slide.addShape(pres.shapes.OVAL, {
+  x: 9.3, y: 5.1, w: 0.4, h: 0.4,
+  fill: { color: theme.accent }
+});
+slide.addText("3", {
+  x: 9.3, y: 5.1, w: 0.4, h: 0.4,
+  fontSize: 12, fontFace: "Arial",
+  color: "FFFFFF", bold: true,
+  align: "center", valign: "middle"
+});
+```
+
+### Pill Badge
+
+```javascript
+slide.addShape(pres.shapes.ROUNDED_RECTANGLE, {
+  x: 9.1, y: 5.15, w: 0.6, h: 0.35,
+  fill: { color: theme.accent },
+  rectRadius: 0.15
+});
+slide.addText("03", {
+  x: 9.1, y: 5.15, w: 0.6, h: 0.35,
+  fontSize: 11, fontFace: "Arial",
+  color: "FFFFFF", bold: true,
+  align: "center", valign: "middle"
+});
+```
+
+---
+
+## Theme Object Contract (MANDATORY)
+
+The compile script passes a theme object with these **exact keys**:
+
+| Key | Purpose | Example |
+|-----|---------|---------|
+| `theme.primary` | Darkest color, titles | `"22223b"` |
+| `theme.secondary` | Dark accent, body text | `"4a4e69"` |
+| `theme.accent` | Mid-tone accent | `"9a8c98"` |
+| `theme.light` | Light accent | `"c9ada7"` |
+| `theme.bg` | Background color | `"f2e9e4"` |
+
+**NEVER use other key names** like `background`, `text`, `muted`, `darkest`, `lightest`.
+
+---
+
+## Subagent Output Format
+
+Each subagent outputs a **complete, runnable JS file**:
+
+```javascript
+// slide-01.js
+const pptxgen = require("pptxgenjs");
+
+const slideConfig = {
+  type: 'cover',
+  index: 1,
+  title: 'Presentation Title'
+};
+
+// ⚠️ MUST be synchronous (not async)
+function createSlide(pres, theme) {
+  const slide = pres.addSlide();
+  slide.background = { color: theme.bg };
+
+  slide.addText(slideConfig.title, {
+    x: 0.5, y: 2, w: 9, h: 1.2,
+    fontSize: 48, fontFace: "Arial",  // English text uses Arial
+    color: theme.primary, bold: true, align: "center"
+  });
+
+  return slide;
+}
+
+// Standalone preview - use slide-specific filename (slide-XX-preview.pptx)
+if (require.main === module) {
+  const pres = new pptxgen();
+  pres.layout = 'LAYOUT_16x9';
+  const theme = {
+    primary: "22223b",
+    secondary: "4a4e69",
+    accent: "9a8c98",
+    light: "c9ada7",
+    bg: "f2e9e4"
+  };
+  createSlide(pres, theme);
+  // Replace XX with actual slide index (01, 02, etc.) to avoid conflicts
+  pres.writeFile({ fileName: "slide-01-preview.pptx" });
+}
+
+module.exports = { createSlide, slideConfig };
+```
+
+---
+
+## Critical Pitfalls
+
+### NEVER use async/await in createSlide()
+
+```javascript
+// ❌ WRONG - compile.js won't await
+async function createSlide(pres, theme) { ... }
+
+// ✅ CORRECT
+function createSlide(pres, theme) { ... }
+```
+
+### NEVER use "#" with hex colors
+
+```javascript
+color: "FF0000"      // ✅ CORRECT
+color: "#FF0000"     // ❌ CORRUPTS FILE
+```
+
+### NEVER encode opacity in hex strings
+
+```javascript
+shadow: { color: "00000020" }              // ❌ CORRUPTS FILE
+shadow: { color: "000000", opacity: 0.12 } // ✅ CORRECT
+```
+
+### Prevent text wrapping in titles
+
+```javascript
+// ✅ Use fit:'shrink' for long titles
+slide.addText("Long Title Here", {
+  x: 0.5, y: 2, w: 9, h: 1,
+  fontSize: 48, fit: "shrink"
+});
+```
+
+---
+
+## Quick Reference
+
+- **Dimensions**: 10" × 5.625" (LAYOUT_16x9)
+- **Colors**: 6-char hex without # (e.g., `"FF0000"`)
+- **English font**: Arial (default), or approved alternatives
+- **Chinese font**: Microsoft YaHei
+- **Page badge position**: x: 9.3", y: 5.1"
+
+---
+
+## QA (Required)
+
+**Assume there are problems. Your job is to find them.**
+
+Your first render is almost never correct. Approach QA as a bug hunt, not a confirmation step. If you found zero issues on first inspection, you weren't looking hard enough.
+
+### Content QA
+
+```bash
+python -m markitdown slide-XX-preview.pptx
+```
+
+Check for missing content, typos, wrong order.
+
+**Check for leftover placeholder text:**
+
+```bash
+python -m markitdown slide-XX-preview.pptx | grep -iE "xxxx|lorem|ipsum|placeholder"
+```
+
+If grep returns results, fix them before declaring success.
+
+### Verification Loop
+
+1. Generate slide → Extract text with `python -m markitdown slide-XX-preview.pptx` → Review content
+2. **List issues found** (if none found, look again more critically)
+3. Fix issues
+4. **Re-verify** — one fix often creates another problem
+5. Repeat until verification reveals no new issues
+
+**Do not declare success until you've completed at least one fix-and-verify cycle.**

+# PptxGenJS Tutorial
+
+## Setup & Basic Structure
+
+```javascript
+const pptxgen = require("pptxgenjs");
+
+let pres = new pptxgen();
+pres.layout = 'LAYOUT_16x9';  // or 'LAYOUT_16x10', 'LAYOUT_4x3', 'LAYOUT_WIDE'
+pres.author = 'Your Name';
+pres.title = 'Presentation Title';
+
+let slide = pres.addSlide();
+slide.addText("Hello World!", { x: 0.5, y: 0.5, fontSize: 36, color: "363636" });
+
+pres.writeFile({ fileName: "Presentation.pptx" });
+```
+
+## Layout Dimensions
+
+Slide dimensions (coordinates in inches):
+- `LAYOUT_16x9`: 10" × 5.625" (default)
+- `LAYOUT_16x10`: 10" × 6.25"
+- `LAYOUT_4x3`: 10" × 7.5"
+- `LAYOUT_WIDE`: 13.3" × 7.5"
+
+---
+
+## Text & Formatting
+
+```javascript
+// Basic text
+slide.addText("Simple Text", {
+  x: 1, y: 1, w: 8, h: 2, fontSize: 24, fontFace: "Arial",
+  color: "363636", bold: true, align: "center", valign: "middle"
+});
+
+// Character spacing (use charSpacing, not letterSpacing which is silently ignored)
+slide.addText("SPACED TEXT", { x: 1, y: 1, w: 8, h: 1, charSpacing: 6 });
+
+// Rich text arrays
+slide.addText([
+  { text: "Bold ", options: { bold: true } },
+  { text: "Italic ", options: { italic: true } }
+], { x: 1, y: 3, w: 8, h: 1 });
+
+// Multi-line text (requires breakLine: true)
+slide.addText([
+  { text: "Line 1", options: { breakLine: true } },
+  { text: "Line 2", options: { breakLine: true } },
+  { text: "Line 3" }  // Last item doesn't need breakLine
+], { x: 0.5, y: 0.5, w: 8, h: 2 });
+
+// Text box margin (internal padding)
+slide.addText("Title", {
+  x: 0.5, y: 0.3, w: 9, h: 0.6,
+  margin: 0  // Use 0 when aligning text with other elements like shapes or icons
+});
+```
+
+**Tip:** Text boxes have internal margin by default. Set `margin: 0` when you need text to align precisely with shapes, lines, or icons at the same x-position.
+
+---
+
+## Lists & Bullets
+
+```javascript
+// ✅ CORRECT: Multiple bullets
+slide.addText([
+  { text: "First item", options: { bullet: true, breakLine: true } },
+  { text: "Second item", options: { bullet: true, breakLine: true } },
+  { text: "Third item", options: { bullet: true } }
+], { x: 0.5, y: 0.5, w: 8, h: 3 });
+
+// ❌ WRONG: Never use unicode bullets
+slide.addText("• First item", { ... });  // Creates double bullets
+
+// Sub-items and numbered lists
+{ text: "Sub-item", options: { bullet: true, indentLevel: 1 } }
+{ text: "First", options: { bullet: { type: "number" }, breakLine: true } }
+```
+
+---
+
+## Shapes
+
+```javascript
+slide.addShape(pres.shapes.RECTANGLE, {
+  x: 0.5, y: 0.8, w: 1.5, h: 3.0,
+  fill: { color: "FF0000" }, line: { color: "000000", width: 2 }
+});
+
+slide.addShape(pres.shapes.OVAL, { x: 4, y: 1, w: 2, h: 2, fill: { color: "0000FF" } });
+
+slide.addShape(pres.shapes.LINE, {
+  x: 1, y: 3, w: 5, h: 0, line: { color: "FF0000", width: 3, dashType: "dash" }
+});
+
+// With transparency
+slide.addShape(pres.shapes.RECTANGLE, {
+  x: 1, y: 1, w: 3, h: 2,
+  fill: { color: "0088CC", transparency: 50 }
+});
+
+// Rounded rectangle (rectRadius only works with ROUNDED_RECTANGLE, not RECTANGLE)
+// ⚠️ Don't pair with rectangular accent overlays — they won't cover rounded corners. Use RECTANGLE instead.
+slide.addShape(pres.shapes.ROUNDED_RECTANGLE, {
+  x: 1, y: 1, w: 3, h: 2,
+  fill: { color: "FFFFFF" }, rectRadius: 0.1
+});
+
+// With shadow
+slide.addShape(pres.shapes.RECTANGLE, {
+  x: 1, y: 1, w: 3, h: 2,
+  fill: { color: "FFFFFF" },
+  shadow: { type: "outer", color: "000000", blur: 6, offset: 2, angle: 135, opacity: 0.15 }
+});
+```
+
+Shadow options:
+
+| Property | Type | Range | Notes |
+|----------|------|-------|-------|
+| `type` | string | `"outer"`, `"inner"` | |
+| `color` | string | 6-char hex (e.g. `"000000"`) | No `#` prefix, no 8-char hex — see Common Pitfalls |
+| `blur` | number | 0-100 pt | |
+| `offset` | number | 0-200 pt | **Must be non-negative** — negative values corrupt the file |
+| `angle` | number | 0-359 degrees | Direction the shadow falls (135 = bottom-right, 270 = upward) |
+| `opacity` | number | 0.0-1.0 | Use this for transparency, never encode in color string |
+
+To cast a shadow upward (e.g. on a footer bar), use `angle: 270` with a positive offset — do **not** use a negative offset.
+
+**Note**: Gradient fills are not natively supported. Use a gradient image as a background instead.
+
+---
+
+## Images
+
+### Image Sources
+
+```javascript
+// From file path
+slide.addImage({ path: "images/chart.png", x: 1, y: 1, w: 5, h: 3 });
+
+// From URL
+slide.addImage({ path: "https://example.com/image.jpg", x: 1, y: 1, w: 5, h: 3 });
+
+// From base64 (faster, no file I/O)
+slide.addImage({ data: "image/png;base64,iVBORw0KGgo...", x: 1, y: 1, w: 5, h: 3 });
+```
+
+### Image Options
+
+```javascript
+slide.addImage({
+  path: "image.png",
+  x: 1, y: 1, w: 5, h: 3,
+  rotate: 45,              // 0-359 degrees
+  rounding: true,          // Circular crop
+  transparency: 50,        // 0-100
+  flipH: true,             // Horizontal flip
+  flipV: false,            // Vertical flip
+  altText: "Description",  // Accessibility
+  hyperlink: { url: "https://example.com" }
+});
+```
+
+### Image Sizing Modes
+
+```javascript
+// Contain - fit inside, preserve ratio
+{ sizing: { type: 'contain', w: 4, h: 3 } }
+
+// Cover - fill area, preserve ratio (may crop)
+{ sizing: { type: 'cover', w: 4, h: 3 } }
+
+// Crop - cut specific portion
+{ sizing: { type: 'crop', x: 0.5, y: 0.5, w: 2, h: 2 } }
+```
+
+### Calculate Dimensions (preserve aspect ratio)
+
+```javascript
+const origWidth = 1978, origHeight = 923, maxHeight = 3.0;
+const calcWidth = maxHeight * (origWidth / origHeight);
+const centerX = (10 - calcWidth) / 2;
+
+slide.addImage({ path: "image.png", x: centerX, y: 1.2, w: calcWidth, h: maxHeight });
+```
+
+### Supported Formats
+
+- **Standard**: PNG, JPG, GIF (animated GIFs work in Microsoft 365)
+- **SVG**: Works in modern PowerPoint/Microsoft 365
+
+---
+
+## Icons
+
+Use react-icons to generate SVG icons, then rasterize to PNG for universal compatibility.
+
+### Setup
+
+```javascript
+const React = require("react");
+const ReactDOMServer = require("react-dom/server");
+const sharp = require("sharp");
+const { FaCheckCircle, FaChartLine } = require("react-icons/fa");
+
+function renderIconSvg(IconComponent, color = "#000000", size = 256) {
+  return ReactDOMServer.renderToStaticMarkup(
+    React.createElement(IconComponent, { color, size: String(size) })
+  );
+}
+
+async function iconToBase64Png(IconComponent, color, size = 256) {
+  const svg = renderIconSvg(IconComponent, color, size);
+  const pngBuffer = await sharp(Buffer.from(svg)).png().toBuffer();
+  return "image/png;base64," + pngBuffer.toString("base64");
+}
+```
+
+### Add Icon to Slide
+
+```javascript
+const iconData = await iconToBase64Png(FaCheckCircle, "#4472C4", 256);
+
+slide.addImage({
+  data: iconData,
+  x: 1, y: 1, w: 0.5, h: 0.5  // Size in inches
+});
+```
+
+**Note**: Use size 256 or higher for crisp icons. The size parameter controls the rasterization resolution, not the display size on the slide (which is set by `w` and `h` in inches).
+
+### Icon Libraries
+
+Install: `npm install -g react-icons react react-dom sharp`
+
+Popular icon sets in react-icons:
+- `react-icons/fa` - Font Awesome
+- `react-icons/md` - Material Design
+- `react-icons/hi` - Heroicons
+- `react-icons/bi` - Bootstrap Icons
+
+---
+
+## Slide Backgrounds
+
+```javascript
+// Solid color
+slide.background = { color: "F1F1F1" };
+
+// Color with transparency
+slide.background = { color: "FF3399", transparency: 50 };
+
+// Image from URL
+slide.background = { path: "https://example.com/bg.jpg" };
+
+// Image from base64
+slide.background = { data: "image/png;base64,iVBORw0KGgo..." };
+```
+
+---
+
+## Tables
+
+```javascript
+slide.addTable([
+  ["Header 1", "Header 2"],
+  ["Cell 1", "Cell 2"]
+], {
+  x: 1, y: 1, w: 8, h: 2,
+  border: { pt: 1, color: "999999" }, fill: { color: "F1F1F1" }
+});
+
+// Advanced with merged cells
+let tableData = [
+  [{ text: "Header", options: { fill: { color: "6699CC" }, color: "FFFFFF", bold: true } }, "Cell"],
+  [{ text: "Merged", options: { colspan: 2 } }]
+];
+slide.addTable(tableData, { x: 1, y: 3.5, w: 8, colW: [4, 4] });
+```
+
+---
+
+## Charts
+
+```javascript
+// Bar chart
+slide.addChart(pres.charts.BAR, [{
+  name: "Sales", labels: ["Q1", "Q2", "Q3", "Q4"], values: [4500, 5500, 6200, 7100]
+}], {
+  x: 0.5, y: 0.6, w: 6, h: 3, barDir: 'col',
+  showTitle: true, title: 'Quarterly Sales'
+});
+
+// Line chart
+slide.addChart(pres.charts.LINE, [{
+  name: "Temp", labels: ["Jan", "Feb", "Mar"], values: [32, 35, 42]
+}], { x: 0.5, y: 4, w: 6, h: 3, lineSize: 3, lineSmooth: true });
+
+// Pie chart
+slide.addChart(pres.charts.PIE, [{
+  name: "Share", labels: ["A", "B", "Other"], values: [35, 45, 20]
+}], { x: 7, y: 1, w: 5, h: 4, showPercent: true });
+```
+
+### Better-Looking Charts
+
+Default charts look dated. Apply these options for a modern, clean appearance:
+
+```javascript
+slide.addChart(pres.charts.BAR, chartData, {
+  x: 0.5, y: 1, w: 9, h: 4, barDir: "col",
+
+  // Custom colors (match your presentation palette)
+  chartColors: ["0D9488", "14B8A6", "5EEAD4"],
+
+  // Clean background
+  chartArea: { fill: { color: "FFFFFF" }, roundedCorners: true },
+
+  // Muted axis labels
+  catAxisLabelColor: "64748B",
+  valAxisLabelColor: "64748B",
+
+  // Subtle grid (value axis only)
+  valGridLine: { color: "E2E8F0", size: 0.5 },
+  catGridLine: { style: "none" },
+
+  // Data labels on bars
+  showValue: true,
+  dataLabelPosition: "outEnd",
+  dataLabelColor: "1E293B",
+
+  // Hide legend for single series
+  showLegend: false,
+});
+```
+
+**Key styling options:**
+- `chartColors: [...]` - hex colors for series/segments
+- `chartArea: { fill, border, roundedCorners }` - chart background
+- `catGridLine/valGridLine: { color, style, size }` - grid lines (`style: "none"` to hide)
+- `lineSmooth: true` - curved lines (line charts)
+- `legendPos: "r"` - legend position: "b", "t", "l", "r", "tr"
+
+---
+
+## Slide Masters
+
+```javascript
+pres.defineSlideMaster({
+  title: 'TITLE_SLIDE', background: { color: '283A5E' },
+  objects: [{
+    placeholder: { options: { name: 'title', type: 'title', x: 1, y: 2, w: 8, h: 2 } }
+  }]
+});
+
+let titleSlide = pres.addSlide({ masterName: "TITLE_SLIDE" });
+titleSlide.addText("My Title", { placeholder: "title" });
+```
+
+---
+
+## Common Pitfalls
+
+⚠️ These issues cause file corruption, visual bugs, or broken output. Avoid them.
+
+1. **NEVER use "#" with hex colors** - causes file corruption
+   ```javascript
+   color: "FF0000"      // ✅ CORRECT
+   color: "#FF0000"     // ❌ WRONG
+   ```
+
+2. **NEVER encode opacity in hex color strings** - 8-char colors (e.g., `"00000020"`) corrupt the file. Use the `opacity` property instead.
+   ```javascript
+   shadow: { type: "outer", blur: 6, offset: 2, color: "00000020" }          // ❌ CORRUPTS FILE
+   shadow: { type: "outer", blur: 6, offset: 2, color: "000000", opacity: 0.12 }  // ✅ CORRECT
+   ```
+
+3. **Use `bullet: true`** - NEVER unicode symbols like "•" (creates double bullets)
+
+4. **Use `breakLine: true`** between array items or text runs together
+
+5. **Avoid `lineSpacing` with bullets** - causes excessive gaps; use `paraSpaceAfter` instead
+
+6. **Each presentation needs fresh instance** - don't reuse `pptxgen()` objects
+
+7. **NEVER reuse option objects across calls** - PptxGenJS mutates objects in-place (e.g. converting shadow values to EMU). Sharing one object between multiple calls corrupts the second shape.
+   ```javascript
+   const shadow = { type: "outer", blur: 6, offset: 2, color: "000000", opacity: 0.15 };
+   slide.addShape(pres.shapes.RECTANGLE, { shadow, ... });  // ❌ second call gets already-converted values
+   slide.addShape(pres.shapes.RECTANGLE, { shadow, ... });
+
+   const makeShadow = () => ({ type: "outer", blur: 6, offset: 2, color: "000000", opacity: 0.15 });
+   slide.addShape(pres.shapes.RECTANGLE, { shadow: makeShadow(), ... });  // ✅ fresh object each time
+   slide.addShape(pres.shapes.RECTANGLE, { shadow: makeShadow(), ... });
+   ```
+
+8. **Don't use `ROUNDED_RECTANGLE` with accent borders** - rectangular overlay bars won't cover rounded corners. Use `RECTANGLE` instead.
+   ```javascript
+   // ❌ WRONG: Accent bar doesn't cover rounded corners
+   slide.addShape(pres.shapes.ROUNDED_RECTANGLE, { x: 1, y: 1, w: 3, h: 1.5, fill: { color: "FFFFFF" } });
+   slide.addShape(pres.shapes.RECTANGLE, { x: 1, y: 1, w: 0.08, h: 1.5, fill: { color: "0891B2" } });
+
+   // ✅ CORRECT: Use RECTANGLE for clean alignment
+   slide.addShape(pres.shapes.RECTANGLE, { x: 1, y: 1, w: 3, h: 1.5, fill: { color: "FFFFFF" } });
+   slide.addShape(pres.shapes.RECTANGLE, { x: 1, y: 1, w: 0.08, h: 1.5, fill: { color: "0891B2" } });
+   ```
