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
- 幻灯片内容清晰可读
- 配色协调，视觉层次分明
- 布局合理，文字不拥挤
质量评级：
- ⭐⭐⭐⭐⭐ 优秀 - 设计精美 + 内容完整 + 自动化生成
- ⭐⭐⭐ 及格 - 内容正确 + PPT 可用 + 格式规范
- ⭐ 失败 - PPT 损坏或内容错误

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
