📖 技能介紹
name: text-to-ppt description: Convert any text input (research reports, summaries, proposals, plans, etc.) into a beautiful HTML-based presentation. Use when the user asks to create a PPT, slides, presentation, deck, or convert text/documents into slides. Also triggers on phrases like "做成PPT", "生成幻燈片", "做個簡報", "轉成slides", "create presentation", "make slides", "text to presentation". Supports data visualization with Chart.js, Font Awesome icons, and modern design themes.
Text-to-PPT — 文本轉 HTML 簡報
Convert any text input into a visually stunning, single-file HTML presentation.
CRITICAL: Two-Phase Generation
ALWAYS use the two-phase approach. NEVER generate the full HTML in one shot.
Phase 1: Plan (fast, single call)
Read the input text, then produce a slide-by-slide outline in JSON format:
{
"title": "Presentation Title",
"language": "zh-CN",
"density": "detailed",
"theme": "dark",
"slides": [
{
"number": 1,
"type": "title",
"heading": "Main Title",
"content": "Subtitle or tagline",
"layout": "centered",
"notes": "Visual: large title with accent underline"
},
{
"number": 2,
"type": "content",
"heading": "Section Title",
"points": ["Point 1", "Point 2", "Point 3"],
"layout": "bullets",
"hasData": false,
"notes": "Use numbered badges for each point"
},
{
"number": 3,
"type": "chart",
"heading": "Key Metrics",
"chartType": "bar",
"chartData": {
"labels": ["A", "B", "C"],
"datasets": [{"label": "Sales", "data": [100, 200, 150]}]
},
"points": ["Insight 1", "Insight 2"],
"layout": "split",
"hasData": true,
"notes": "Left: chart, Right: insights as stat cards"
}
]
}
Rules for Phase 1:
- Output ONLY the JSON plan. No HTML. No explanation.
- Identify data points → mark hasData: true and provide chartType + chartData
- Choose layout: centered, bullets, split, grid, timeline, cards, fullchart, quote
- Target 8-15 slides. Never exceed 20.
- This should take <10 seconds.
Phase 2: Generate (parallel, page-by-page)
Read references/design-system.md — this is where the full design spec lives.

Then generate HTML for each slide independently. Each slide is a self-contained <div class="slide"> block.
For each slide, the agent should:
1. Take ONE slide from the plan (by number)
2. Read only the design system reference if not already loaded
3. Generate ONLY that one slide's HTML <div class="slide">...</div>
4. No <html>, no <head>, no <body> — just the slide div
BATCHING: Generate slides in parallel using sub-agents. Spawn up to 5 sub-agents simultaneously, each generating 1-2 slides.
Phase 3: Assemble
After all slides are generated:
1. Read the shell template from references/shell-template.html
2. Insert all slide divs into the shell
3. Ensure chart canvas IDs are unique across all slides
4. Save to Obsidian vault: ~/Documents/longhai/Longhai/
5. Tell user the file path
Execution Strategy
When running as the main agent:
- Phase 1 yourself (fast, just JSON)
- Write the plan to a temp file
- Spawn sub-agents for Phase 2 (parallel slide generation)
- Collect results and assemble in Phase 3
Sub-agent task format (for Phase 2):
Generate HTML for slide {N} of a presentation.
SLIDE PLAN:
{JSON for this specific slide}
DESIGN SYSTEM: Read references/design-system.md for theme colors, components, and rules.
OUTPUT: Return ONLY a single <div class="slide" style="background-color: #0f172a;">...</div> block.
No <html>, <head>, or <body> tags. Use inline styles. Include <script> for Chart.js if this slide has charts.
Use unique canvas ID: chart-slide{N}-{random}.
Input Sources
- Directly pasted text
- A file path — read it first with
read - A URL — fetch it first with
web_fetch - An Obsidian note path — read it first
Output
- Single self-contained HTML file
- File naming:
{topic-slug}.presentation.html - Default save location:
~/Documents/longhai/Longhai/ - Tell the user the file path
Theme Options
| Theme | Background | Text | Cards | Accent |
|---|---|---|---|---|
| dark (default) | slate-900 | slate-50 | slate-800 | blue-500/amber-500 |
| light | slate-50 | slate-900 | white | blue-600/amber-600 |
