Ppt Generation

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:

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

1. 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

1. 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 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

1. Continue for all remaining slides, always referencing the previous slide:

# 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

Step 4: Compose PPT

After all slide images are generated, call the composition script:

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

Parameters:

• --plan-file: Absolute path to the presentation plan JSON file (required)
• --slide-images: Absolute paths to slide images in order (required, space-separated)
• --output-file: Absolute path to output PPTX file (required)

[!NOTE] Do NOT read the python file, just call it with the parameters.
