--- name: ppt-presenter description: Create professional HTML presentations with complete word-for-word speaker scripts (逐字稿) and presenter view. Use when user asks to create a presentation, PPT, slides, tech sharing, keynote, or talk. Core feature: every slide comes with a full speaker script (150-300 words) visible in presenter view (press S) — so you can present confidently without memorizing anything. Full pipeline: (1) content planning and outline, (2) per-slide content with three-audience-layer explanations, (3) AI-generated whiteboard illustrations via Gemini API, (4) reveal.js HTML assembly with lightbox, (5) word-for-word 逐字稿 in presenter view.

Content Planning (outline + page count) ↓ 2. Per-Slide Content (title, board description, speaker notes) ↓ 3. Image Generation (Gemini 3 Pro Image, one per slide) ↓ 4. HTML Assembly (reveal.js + lightbox + presenter view) ↓ 5. Speaker Scripts (word-for-word 逐字稿 in <aside class="notes">) ``` ## Step 1: Content Planning From user's topic, notes, or markdown files, produce an outline: - Determine audience (technical level, mixed audiences) - Plan 15-25 slides grouped into 4-7 sections - Each section gets a divider slide (colored section number + title) - Structure: Opening hook → Sections → Quick Start → Takeaway + Q&A If user provides existing markdown/text content, read it and restructure into slide outline. Ask user to confirm page count and structure before proceeding. ## Step 2: Per-Slide Content For each slide, define: - **Page title** — concise, with emoji prefix - **Visual description** — what to draw on a whiteboard (colors, layout, diagrams) - **Key content** — bullet points, tables, code blocks, comparison charts - **Speaker script** — 150-300 words per slide, conversational tone, can be read aloud directly For mixed audiences, write three-layer explanations: - 编程小白 (beginners): metaphors, daily-life analogies - 职场白领 (business): ROI, efficiency, practical scenarios - 开发人员 (developers): architecture, code, protocols Write content to a markdown file first for user review, then proceed to image generation. ## Step 3: Image Generation Generate one whiteboard-style illustration per slide using Gemini API. Use the script: `scripts/generate_slide_images.py` ```bash python3 scripts/generate_slide_images.py \ --prompts-file prompts.json \ --output-dir ./images \ --api-key "$GEMINI_API_KEY" ``` ### Prompt Guidelines - Style: "whiteboard marker drawing, hand-drawn educational style, colorful markers (red, blue, green, orange)" - Include Chinese text in prompts when audience is Chinese - Describe specific visual elements: diagrams, flowcharts, comparison tables, icons - Keep prompts under 500 chars for best results ### API Details - Model: `gemini-3-pro-image-preview` (preferred) or `imagen-4.0-generate-001` - Endpoint: `https://generativelanguage.googleapis.com/v1beta/models/{model}:generateContent` - Request body for Gemini 3: ```json { "contents": [{"parts": [{"text": "Generate this image: {prompt}"}]}], "generationConfig": {"responseModalities": ["IMAGE", "TEXT"]} } ``` - Response: `candidates[0].content.parts[].inlineData.data` (base64) - Rate limit: add 2-3 second delay between requests - Retry on network errors (SSL EOF, connection reset) ### Finding API Key Check TOOLS.md for `Gemini Image Generation` section, or ask user for API key. ## Step 4: HTML Assembly Use the template: `assets/reveal-template.html` ### Structure ```html <!DOCTYPE html> <html lang="zh-CN"> <head> <!-- reveal.js 5.1.0 from CDN --> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/reveal.js@5.1.0/dist/reveal.css"> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/reveal.js@5.1.0/dist/theme/black.css"> <!-- Custom styles (see template) --> </head> <body> <div class="reveal"><div class="slides"> <!-- Section dividers: colored background gradient + section number --> <section data-background-gradient="..."> <div class="section-num">1</div> <h2>Section Title</h2> </section> <!-- Content slides --> <section> <h2>Slide Title</h2> <!-- Content: .two-col, .three-col, .card, table, .code-block, .timeline --> <aside class="notes">Speaker script here...</aside> </section> </div></div> <!-- Lightbox overlay (see template) --> <!-- reveal.js init + lightbox JS (see template) --> </body> </html> ``` ### Key CSS Classes (defined in template) | Class | Use | |-------|-----| | `.card` | Dark rounded content box | | `.two-col` / `.three-col` | Flex column layouts | | `.code-block` | Styled code with `.comment`, `.cmd`, `.flag` | | `.warning-box` | Red-border alert box | | `.slide-img` | Clickable image (max-height 420px) | | `.flow-box` + `.flow-arrow` | Horizontal flow diagrams | | `.timeline` + `.timeline-item` | Vertical timeline with colored dots | | `.tag-blue/green/red/orange/purple` | Colored pill tags | | `.accent/.green/.red/.blue/.purple/.yellow/.pink` | Text colors | | `.checklist` | Checkbox-style list | | `.photo-row` | Horizontal image gallery | | `.gradient-text` | Gradient colored heading | ### Lightbox Feature All images with `.slide-img`, `.slide-img-large`, `.slide-img-full`, or inside `.photo-row` are clickable. Clicking opens fullscreen lightbox with: - Left/right navigation (arrows + keyboard) - Counter (current/total) - Close button + ESC key - Pauses reveal.js keyboard while open The lightbox JS is included in the template. ### reveal.js Configuration ```javascript Reveal.initialize({ hash: true, slideNumber: 'c/t', transition: 'slide', width: 1280, height: 720, margin: 0.06, plugins: [RevealHighlight, RevealNotes] }); ``` Keyboard hints shown at bottom: `← → 翻页 · S 演讲者视图 · F 全屏 · O 总览` ## Step 5: Speaker Scripts Add `<aside class="notes">` to every content slide (not section dividers). ### Script Guidelines - **Length**: 150-300 words per slide (1-2 minutes speaking time) - **Tone**: Conversational, as if speaking to audience directly - **Structure**: Hook → explain visual → key points → transition to next - **Language**: Match audience language (Chinese for Chinese audience) - **Include**: Analogies, real examples, audience engagement ("大家看...") - **Avoid**: Reading bullet points verbatim; scripts should expand on slide content ### Presenter View User presses `S` to open presenter view showing: - Current slide (left) - Speaker notes/script (right) - Next slide preview - Timer ## Output Checklist Before delivering, verify: - [ ] All slides have titles with emoji prefixes - [ ] All content slides have `<aside class="notes">` with full scripts - [ ] All slide images generated and saved to `images/` directory - [ ] Images use `.slide-img` class (clickable lightbox) - [ ] Section dividers have colored backgrounds and section numbers - [ ] Lightbox JS is included and functional - [ ] reveal.js loads from CDN (no local dependencies) - [ ] File opens correctly in browser (`open index.html`)
