description: Use this skill when the user requests to generate, create, or make presentations (PPT/PPTX). Creates visually rich slides by generating images for each slide and composing them into a PowerPoint file.

PPT Generation Skill

Overview

This skill generates professional PowerPoint presentations by creating AI-generated images for each slide and composing them into a PPTX file. The workflow includes planning the presentation structure with a consistent visual style, generating slide images sequentially (using the previous slide as a reference for style consistency), and assembling them into a final presentation.

Core Capabilities

• Plan and structure multi-slide presentations with unified visual style
• Support multiple presentation styles: Business, Academic, Minimal, Apple Keynote, Creative
• Generate unique AI images for each slide using image-generation skill
• Maintain visual consistency by using previous slide as reference image
• Compose images into a professional PPTX file

Presentation Styles

Choose one of the following styles when creating the presentation plan:

| Style | Description | Best For | |-------|-------------|----------| | **glassmorphism** | Frosted glass panels with blur effects, floating translucent cards, vibrant gradient backgrounds, depth through layering | Tech products, AI/SaaS demos, futuristic pitches | | **dark-premium** | Rich black backgrounds (#0a0a0a), luminous accent colors, subtle glow effects, luxury brand aesthetic | Premium products, executive presentations, high-end brands | | **gradient-modern** | Bold mesh gradients, fluid color transitions, contemporary typography, vibrant yet sophisticated | Startups, creative agencies, brand launches | | **neo-brutalist** | Raw bold typography, high contrast, intentional "ugly" aesthetic, anti-design as design, Memphis-inspired | Edgy brands, Gen-Z targeting, disruptive startups | | **3d-isometric** | Clean isometric illustrations, floating 3D elements, soft shadows, tech-forward aesthetic | Tech explainers, product features, SaaS presentations | | **editorial** | Magazine-quality layouts, sophisticated typography hierarchy, dramatic photography, Vogue/Bloomberg aesthetic | Annual reports, luxury brands, thought leadership | | **minimal-swiss** | Grid-based precision, Helvetica-inspired typography, bold use of negative space, timeless modernism | Architecture, design firms, premium consulting | | **keynote** | Apple-inspired aesthetic with bold typography, dramatic imagery, high contrast, cinematic feel | Keynotes, product reveals, inspirational talks |

Workflow

Step 1: Understand Requirements

When a user requests presentation generation, identify:

• Topic/subject: What is the presentation about
• Number of slides: How many slides are needed (default: 5-10)
• **Style**: business / academic / minimal / keynote / creative
• Aspect ratio: Standard (16:9) or classic (4:3)
• Content outline: Key points for each slide
• You don't need to check the folder under `/mnt/user-data`

Step 2: Create Presentation Plan

Create a JSON file in `/mnt/user-data/workspace/` with the presentation structure. **Important**: Include the `style` field to define the overall visual consistency.

{
  "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"
    }
  ]
}

Step 3: Generate Slide Images Sequentially

**IMPORTANT**: Generate slides **strictly one by one, in order**. Do NOT parallelize or batch image generation. Each slide depends on the previous slide's output as a reference image. Generating slides in parallel will break visual consistency and is not allowed.

1. Read the image-generation skill: `/mnt/skills/public/image-generation/SKILL.md`

2. **For the FIRST slide (slide 1)**, create a prompt that establishes the visual style:

{
  "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. **For subsequent slides (slide 2+)**, use the PREVIOUS slide as a reference image:

{
  "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 th
