## 核心流程

```
用户需求 → 内容分析 → 配色选择 → 工具选择 → 生成 PPT → 验证输出
User request → Content analysis → Color palette → Tool selection → Generate PPT → Validate
```

**任务类型判断 (Task Classification)**：

### Creating Presentations (创建演示文稿)
- **HTML to PPT Workflow (推荐 / RECOMMENDED)**
  - Write HTML slides with styling
  - Convert using html2pptx library
  - Accurate positioning and formatting
  - Web-safe fonts only (Arial, Helvetica, Georgia, etc.)
  
- **Python-PPTX Workflow**
  - Programmatic slide creation
  - Batch generation from data
  - Template-based automation

### Reading & Analysis (读取与分析)
- **Text extraction** → markitdown (convert to markdown)
- **Comments & Notes** → Unpack OOXML and read XML
- **Design analysis** → Extract theme, colors, fonts from XML

### Editing Existing (编辑已有文稿)
- **Simple edits** → python-pptx library
- **Complex edits** → Unpack OOXML, modify XML, repack

---

## 任务完成标准

**必须满足**（缺一不可）：
- PPT 可正常打开并播放

## 关键原则（AI 必读 / Critical Principles）

### 1. Design First - Content-Informed Approach (设计先行)
**CRITICAL**: Before creating any presentation, analyze the content:
- **Consider subject matter**: What is this about? What tone/industry/mood?
- **Check branding**: If company mentioned, consider brand colors
- **Match palette to content**: Select colors reflecting the subject
- **State your approach**: Explain design choices BEFORE writing code

### 2. Web-Safe Fonts Only (仅使用 Web 安全字体)
**Allowed fonts**: Arial, Helvetica, Times New Roman, Georgia, Courier New, Verdana, Tahoma, Trebuchet MS, Impact
- **No custom fonts**: They won't render correctly
- **Font pairing**: Use max 2-3 fonts per presentation

### 3. Visual Hierarchy (视觉层次)
- **Extreme size contrast**: 72pt headlines vs 11pt body text
- **Weight variation**: Bold headers, normal body, light captions
- **Color emphasis**: Use accent color for key information
- **Clear structure**: Title → Main content → Supporting details

### 4. Chart & Table Layout Rules (图表布局规则)
**PREFERRED - Two-column layout**:
- Header spanning full width
- Text/bullets in one column (40%) + Chart/table in other (60%)
- Better balance and readability

**Alternative - Full-slide layout**:
- Chart/table takes entire slide for maximum impact

**NEVER vertically stack**:
- ❌ Do NOT place charts/tables below text in single column
- ❌ Causes poor readability and layout issues

### 5. Color Palette Selection (18种配色方案)
**Think beyond defaults**: What colors genuinely match this topic?
**Consider multiple angles**: Topic, industry, mood, energy, audience, brand
**Be adventurous**: Healthcare doesn't have to be green, finance doesn't have to be navy

## 常见场景示例 (Common Scenarios)

### Scenario 1: Create Professional Title Slide (创建专业标题页)
```python
from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.dml.color import RGBColor

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[6])  # Blank layout

# Add title
left = Inches(1)
top = Inches(2.5)
width = Inches(8)
height = Inches(1.5)
title_box = slide.shapes.add_textbox(left, top, width, height)
title_frame = title_box.text_frame
title_frame.text = "2024 Sales Report"

# Format title
title_para = title_frame.paragraphs[0]
title_para.font.size = Pt(72)
title_para.font.bold = True
title_para.font.color.rgb = RGBColor(28, 40, 51)  # Navy

# Add subtitle
subtitle_box = slide.shapes.add_textbox(left, Inches(4), width, Inches(0.5))
subtitle_frame = subtitle_box.text_frame
subtitle_frame.text = "Q4 Performance Review"
subtitle_para = subtitle_frame.paragraphs[0]
subtitle_para.font.size = Pt(24)
subtitle_para.font.color.rgb = RGBColor(46, 64, 83)  # Slate

prs.save("title_slide.pptx")
```

### Scenario 2: Extract All Speaker Notes (提取所有演讲者备注)
```bash
# Step 1: Unpack PPTX
python ooxml/scripts/unpack.py presentation.pptx unpacked/

# Step 2: Extract notes using grep
cd unpacked/ppt/notesSlides/
grep -r "a:t>" . | sed 's/<[^>]*>//g' > ../../all_notes.txt
```

### Scenario 3: Batch Generate Slides from Data (批量生成幻灯片)
```python
from pptx import Presentation
from pptx.util import Inches, Pt

data = [
    {"name": "Product A", "sales": 1200, "growth": "15%"},
    {"name": "Product B", "sales": 980, "growth": "8%"},
    {"name": "Product C", "sales": 1450, "growth": "22%"}
]

prs = Presentation()

for item in data:
    slide = prs.slides.add_slide(prs.slide_layouts[1])  # Title and content
    title = slide.shapes.title
    title.text = item["name"]
    
    body = slide.placeholders[1]
    tf = body.text_frame
    tf.text = f"Sales: ${item['sales']}M"
    
    p = tf.add_paragraph()
    p.text = f"Growth: {item['growth']}"
    p.level = 1

prs.save("batch_report.pptx")
```
