Reading Content

# Text extraction
python -m markitdown presentation.pptx

Creating from Scratch — Workflow

Use when no template or reference presentation is available.

Step 1: Research & Requirements

Search to understand user requirements — topic, audience, purpose, tone, content depth.

Step 2: Select Color Palette & Fonts

Use the Color Palette Reference to select a palette matching the topic and audience. Use the Font Reference to choose a font pairing.

Step 3: Select Design Style

Use the Style Recipes to choose a visual style (Sharp, Soft, Rounded, or Pill) matching the presentation tone.

Step 4: Plan Slide Outline

Classify every slide as exactly one of the 5 page types. Plan the content and layout for each slide. Ensure visual variety — do NOT repeat the same layout across slides.

Step 5: Generate Slide JS Files

Create one JS file per slide in slides/ directory. Each file must export a synchronous createSlide(pres, theme) function. Follow the Slide Output Format and the type-specific guidance in slide-types.md. Generate up to 5 slides concurrently using subagents if available.

Tell each subagent:

File naming: slides/slide-01.js, slides/slide-02.js, etc.
Images go in: slides/imgs/
Final PPTX goes in: slides/output/
Dimensions: 10" x 5.625" (LAYOUT_16x9)
Fonts: Chinese = Microsoft YaHei, English = Arial (or approved alternative)
Colors: 6-char hex without # (e.g. "FF0000")
Must use the theme object contract (see Theme Object Contract)
Must follow the PptxGenJS API reference

Step 6: Compile into Final PPTX

Create slides/compile.js to combine all slide modules:

// slides/compile.js
const pptxgen = require('pptxgenjs');
const pres = new pptxgen();
pres.layout = 'LAYOUT_16x9';

const theme = {
  primary: "22223b",    // dark color for backgrounds/text
  secondary: "4a4e69",  // secondary accent
  accent: "9a8c98",     // highlight color
  light: "c9ada7",      // light accent
  bg: "f2e9e4"          // background color
};

for (let i = 1; i <= 12; i++) {  // adjust count as needed
  const num = String(i).padStart(2, '0');
  const slideModule = require(`./slide-${num}.js`);
  slideModule.createSlide(pres, theme);
}

pres.writeFile({ fileName: './output/presentation.pptx' });

Run with: cd slides && node compile.js

Step 7: QA (Required)

See QA Process.

Output Structure

slides/
├── slide-01.js          # Slide modules
├── slide-02.js
├── ...
├── imgs/                # Images used in slides
└── output/              # Final artifacts
    └── presentation.pptx

Slide Output Format

Each slide is a complete, runnable JS file:

// 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",
    color: theme.primary, bold: true, align: "center"
  });

  return slide;
}

// Standalone preview - use slide-specific filename
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);
  pres.writeFile({ fileName: "slide-01-preview.pptx" });
}

module.exports = { createSlide, slideConfig };

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.

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)

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

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"
});

Dependencies

pip install "markitdown[pptx]" — text extraction
npm install -g pptxgenjs — creating from scratch
npm install -g react-icons react react-dom sharp — icons (optional)

minimax-pdf

modelscope.cn

Use this skill when visual quality and design identity matter for a PDF. CREATE (generate from scratch): "make a PDF", "generate a report", "write a proposal", "create a resume", "beautiful PDF", "professional document", "cover page", "polished PDF", "client-ready document". FILL (complete form fields): "fill in the form", "fill out this PDF", "complete the form fields", "write values into PDF", "what fields does this PDF have". REFORMAT (apply design to an existing doc): "reformat this document", "apply our style", "convert this Markdown/text to PDF", "make this doc look good", "re-style this PDF". This skill uses a token-based design system: color, typography, and spacing are derived from the document type and flow through every page. The output is print-ready. Prefer this skill when appearance matters, not just when any PDF output is needed.
