工作流

第 1 步：了解需求

用户请求生成演示文稿时，请确定：

• 主题/内容：演示文稿的主题是什么
• 幻灯片数量：需要多少张幻灯片（默认：5-10 张）
• 风格：商务 / 学术 / 极简 / keynote / 创意
• 宽高比：标准（16:9）或经典（4:3）
• 内容大纲：每张幻灯片的要点
• 无需检查 /mnt/user-data 下的文件夹

第 2 步：制定演示文稿计划

在 /mnt/user-data/workspace/ 中创建包含演示文稿结构的 JSON 文件。重要：请包含 style 字段，以定义整体视觉一致性。

{
  "title": "Presentation Title",
  "style": "keynote",
  "style_guidelines": {
    "color_palette": "Deep black backgrounds, white text, single accent color (blue or orange)",
    "typography": "Bold sans-serif headlines, clean body text, dramatic size contrast",
    "imagery": "High-quality photography, full-bleed images, cinematic composition",
    "layout": "Generous whitespace, centered focus, minimal elements per slide"
  },
  "aspect_ratio": "16:9",
  "slides": [
    {
      "slide_number": 1,
      "type": "title",
      "title": "Main Title",
      "subtitle": "Subtitle or tagline",
      "visual_description": "Detailed description for image generation"
    },
    {
      "slide_number": 2,
      "type": "content",
      "title": "Slide Title",
      "key_points": ["Point 1", "Point 2", "Point 3"],
      "visual_description": "Detailed description for image generation"
    }
  ]
}

第 3 步：按顺序生成幻灯片图像

重要：必须严格按顺序逐张生成幻灯片。不要并行处理或批量生成图像。每张幻灯片都依赖上一张幻灯片的输出作为参考图像。并行生成幻灯片会破坏视觉一致性，因此不允许这样做。

1. 阅读图像生成技能：/mnt/skills/public/image-generation/SKILL.md

2. 对于第一张幻灯片（幻灯片 1），创建一个用于确立视觉风格的提示词：

{
  "prompt": "Professional presentation slide. [style_guidelines from plan]. Title: 'Your Title'. [visual_description]. This slide establishes the visual language for the entire presentation.",
  "style": "[Based on chosen style - e.g., Apple Keynote aesthetic, dramatic lighting, cinematic]",
  "composition": "Clean layout with clear text hierarchy, [style-specific composition]",
  "color_palette": "[From style_guidelines]",
  "typography": "[From style_guidelines]"
}

python /mnt/skills/public/image-generation/scripts/generate.py \
  --prompt-file /mnt/user-data/workspace/slide-01-prompt.json \
  --output-file /mnt/user-data/outputs/slide-01.jpg \
  --aspect-ratio 16:9

3. 对于后续幻灯片（幻灯片 2 及之后），使用上一张幻灯片作为参考图像：

{
  "prompt": "Professional presentation slide continuing the visual style from the reference image. Maintain the same color palette, typography style, and overall aesthetic. Title: 'Slide Title'. [visual_description]. Keep visual consistency with the reference.",
  "style": "Match the style of the reference image exactly",
  "composition": "Similar layout principles as reference, adapted for this content",
  "color_palette": "Same as reference image",
  "consistency_note": "This slide must look like it belongs in the same presentation as the reference image"
}

python /mnt/skills/public/image-generation/scripts/generate.py \
  --prompt-file /mnt/user-data/workspace/slide-02-prompt.json \
  --reference-images /mnt/user-data/outputs/slide-01.jpg \
  --output-file /mnt/user-data/outputs/slide-02.jpg \
  --aspect-ratio 16:9

4. 继续生成所有剩余幻灯片，始终参考上一张幻灯片：

# Slide 3 references slide 2
python /mnt/skills/public/image-generation/scripts/generate.py \
  --prompt-file /mnt/user-data/workspace/slide-03-prompt.json \
  --reference-images /mnt/user-data/outputs/slide-02.jpg \
  --output-file /mnt/user-data/outputs/slide-03.jpg \
  --aspect-ratio 16:9

# Slide 4 references slide 3
python /mnt/skills/public/image-generation/scripts/generate.py \
  --prompt-file /mnt/user-data/workspace/slide-04-prompt.json \
  --reference-images /mnt/user-data/outputs/slide-03.jpg \
  --output-file /mnt/user-data/outputs/slide-04.jpg \
  --aspect-ratio 16:9

第 4 步：合成 PPT

生成所有幻灯片图像后，调用合成脚本：

带有 EXIF 方向元数据的照片会在调整尺寸和嵌入前旋转或镜像，以保留其在演示文稿中的显示方向。

透明幻灯片图像会在演示文稿中保留其 Alpha 通道。不透明图像仍按之前的方式以 JPEG 格式嵌入。

python /mnt/skills/public/ppt-generation/scripts/generate.py \
  --plan-file /mnt/user-data/workspace/presentation-plan.json \
  --slide-images /mnt/user-data/outputs/slide-01.jpg /mnt/user-data/outputs/slide-02.jpg /mnt/user-data/outputs/slide-03.jpg \
  --output-file /mnt/user-data/outputs/presentation.pptx

参数：

• --plan-file：演示文稿计划 JSON 文件的绝对路径（必需）
• --slide-images：按顺序排列的幻灯片图像绝对路径（必需，以空格分隔）
• --output-file：输出 PPTX 文件的绝对路径（必需）

[!NOTE] 请勿读取 Python 文件，只需使用这些参数调用它。

  "composition": "Centered glass card as focal point, floating 3D elements creating depth at edges, 40% negative space, clear visual hierarchy",
  "lighting": "Soft ambient glow from gradient, light refraction through glass elements, subtle rim lighting on 3D shapes",
  "color_palette": "Purple gradient #667eea, magenta #f093fb, cyan #00d4ff, frosted white rgba(255,255,255,0.15), pure white text #ffffff",
  "effects": "Backdrop blur on glass panels, soft drop shadows with color tint, light refraction, subtle noise texture on glass, floating particles"
}

python /mnt/skills/public/image-generation/scripts/generate.py \
  --prompt-file /mnt/user-data/workspace/nova-slide-01.json \
  --output-file /mnt/user-data/outputs/nova-slide-01.jpg \
  --aspect-ratio 16:9

幻灯片 2 - 内容（必须参考幻灯片 1 以保持一致）：

创建 /mnt/user-data/workspace/nova-slide-02.json：

{
  "prompt": "Presentation slide continuing EXACT visual style from reference image. SAME purple-to-cyan gradient background, SAME glassmorphism aesthetic, SAME typography style. Left side: frosted glass card with backdrop blur containing title 'Why Nova?' in bold white (matching reference font style), three feature points as subtle glass pill badges below. Right side: abstract 3D neural network visualization made of interconnected glass nodes with soft cyan glow, floating in space. Floating translucent geometric shapes (matching style from reference) adding depth. The frosted glass has identical treatment: white border, purple-tinted shadow, same blur intensity. CRITICAL: This slide must look like it belongs in the exact same presentation as the reference image - same colors, same glass treatment, same overall aesthetic.",
  "style": "MATCH REFERENCE EXACTLY - Glassmorphism, visionOS aesthetic, same visual language",
  "composition": "Asymmetric split: glass card left (40%), 3D visualization right (40%), breathing room between elements",
  "color_palette": "EXACTLY match reference: purple #667eea, cyan #00d4ff gradient, same frosted white treatment, same text white",
  "consistency_note": "CRITICAL: Must be visually identical in style to reference image. Same gradient colors, same glass blur intensity, same shadow treatment, same typography weight and style. Viewer should immediately recognize this as the same presentation."

输出处理

生成后：

• PPTX 文件保存在 /mnt/user-data/outputs/
• 使用 present_files 工具与用户分享生成的演示文稿
• 如果用户提出要求，也分享单张幻灯片图像
• 简要介绍演示文稿
• 提供修改或重新生成特定幻灯片的选项

备注

关键质量指南

打造专业效果的提示词工程：

• 无论用户使用何种语言，图像提示词始终使用英语
• 对视觉细节进行极其具体的描述——模糊的提示词会产生千篇一律的结果
• 包含准确的十六进制颜色代码（例如 #667eea，而不是“紫色”）
• 指定排版细节：字重（400/700）、字号层级、字间距
• 精确描述效果：“backdrop blur 20px”“drop shadow 8px blur 30% opacity”
• 参考真实设计系统：“visionOS aesthetic”“Stripe website style”“Bloomberg Businessweek layout”

视觉一致性（最重要）：

• 按顺序生成幻灯片——每张幻灯片都必须参考上一张
• 第一张幻灯片至关重要——它奠定了整个演示文稿的视觉语言
• 在后续每张幻灯片的提示词中，明确写明：“continuing EXACT visual style from reference image”
• 在提示词中着重使用 SAME、EXACT、MATCH 等关键词，以确保一致性
• 在第 1 张之后的每个 JSON 提示词中，都包含 consistency_note 字段
• 如果某张幻灯片看起来不一致，请加重参考图的提示，重新生成

现代美学设计原则：

• 善用留白——40-60% 的空白区域能营造高级感
• 限制每张幻灯片的元素数量——一个焦点，一个主题
• 通过分层营造纵深感（阴影、透明度、z-depth）
• 排版层级：超大标题（72pt 以上）、舒适的正文（18-24pt）
• 克制使用颜色：一个主色调，最多搭配 1-2 种强调色

应避免的常见错误：

• ❌ 使用“专业幻灯片”这类泛泛的提示词——描述要具体
• ❌ 每张幻灯片包含过多元素或文字——内容杂乱显得不专业
• ❌ 幻灯片之间的颜色不一致——始终参考上一张幻灯片
• ❌ 跳过参考图参数——这会破坏视觉一致性
• ❌ 在同一份演示文稿中使用不同的设计风格
• ❌ 并行生成幻灯片——必须按顺序逐张生成（第 1 张 → 第 2 张 → 第 3 张……），绝不能同时生成

不同场景的推荐风格：

• 科技产品发布 → glassmorphism 或 gradient-modern
• 奢侈品／高端品牌 → dark-premium 或 editorial
• 初创公司路演 → gradient-modern 或 minimal-swiss
• 高管演示 → dark-premium 或 keynote
• 创意机构 → neo-brutalist 或 gradient-modern
• 数据／分析 → minimal-swiss 或 3d-isometric
