It includes a complete design system (color palettes, fonts, style recipes) and detailed guidance for every slide type. Quick Reference Task Approach Read/analyze content python -m markitdown presentation.pptx Edit or create from template See Editing Presentations Create from scratch See Creating from Scratch below Item Value Dimensions 10\" x 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\" Theme keys primary , secondary , accent , light , bg Shapes RECTANGLE, OVAL, LINE, ROUNDED_RECTANGLE Charts BAR, LINE, PIE, DOUGHNUT, SCATTER, BUBBLE, RADAR Reference Files File Contents slide-types.md 5 slide page types (Cover, TOC, Section Divider, Content, Summary) + additional layout patterns design-system.md Color palettes, font reference, style recipes (Sharp/Soft/Rounded/Pill), typography & spacing editing.md Template-based editing workflow, XML manipulation, formatting rules, common pitfalls pitfalls.md QA process, common mistakes, critical PptxGenJS pitfalls pptxgenjs.md Complete PptxGenJS API reference 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)",
