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)",

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.

Read the image-generation skill: /mnt/skills/public/image-generation/SKILL.md
For the FIRST slide (slide 1), create a prompt that establishes the visual style:

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

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

Step 4: Compose PPT

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

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.

Complete Example: Glassmorphism Style (最现代前卫)

User request: "Create a presentation about AI product launch"

Step 1: Create presentation plan

Create /mnt/user-data/workspace/ai-product-plan.json:

Step 2: Read image-generation skill

Read /mnt/skills/public/image-generation/SKILL.md to understand how to generate images.

Step 3: Generate slide images sequentially with reference chaining

Slide 1 - Title (establishes the visual language):

Create /mnt/user-data/workspace/nova-slide-01.json:

Slide 2 - Content (MUST reference slide 1 for consistency):

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

Slides 3-5: Continue the same pattern, each referencing the previous slide

Key consistency rules for subsequent slides:

Always include "continuing EXACT visual style from reference image" in prompt
Specify "SAME gradient background", "SAME glass treatment", "SAME typography"
Include consistency_note emphasizing style matching
Reference the immediately previous slide image

Step 4: Compose final PPT

Style-Specific Guidelines

Glassmorphism Style (推荐 - 最现代前卫)

Dark Premium Style

Gradient Modern Style

Neo-Brutalist Style

3D Isometric Style

Editorial Style

Minimal Swiss Style

Keynote Style (Apple风格)

Output Handling

After generation:

The PPTX file is saved in /mnt/user-data/outputs/
Share the generated presentation with user using present_files tool
Also share the individual slide images if requested
Provide brief description of the presentation
Offer to iterate or regenerate specific slides if needed

Notes

Critical Quality Guidelines

Prompt Engineering for Professional Results:

Always use English for image prompts regardless of user's language
Be EXTREMELY specific about visual details - vague prompts produce generic results
Include exact hex color codes (e.g., #667eea not "purple")
Specify typography details: font weight (400/700), size hierarchy, letter-spacing
Describe effects precisely: "backdrop blur 20px", "drop shadow 8px blur 30% opacity"
Reference real design systems: "visionOS aesthetic", "Stripe website style", "Bloomberg Businessweek layout"

Visual Consistency (Most Important):

Generate slides sequentially - each slide MUST reference the previous one
The first slide is critical - it establishes the visual language for the entire presentation
In every subsequent slide prompt, explicitly state: "continuing EXACT visual style from reference image"
Use SAME, EXACT, MATCH keywords emphatically in prompts to enforce consistency
Include a consistency_note field in every JSON prompt after slide 1
If a slide looks inconsistent, regenerate it with STRONGER reference emphasis

Design Principles for Modern Aesthetics:

Embrace negative space - 40-60% empty space creates premium feel
Limit elements per slide - one focal point, one message
Use depth through layering (shadows, transparency, z-depth)
Typography hierarchy: massive headlines (72pt+), comfortable body (18-24pt)
Color restraint: one primary palette, 1-2 accent colors maximum

Common Mistakes to Avoid:

❌ Generic prompts like "professional slide" - be specific
❌ Too many elements/text per slide - cluttered = unprofessional
❌ Inconsistent colors between slides - always reference previous slide
❌ Skipping the reference image parameter - this breaks visual consistency
❌ Using different design styles within one presentation
❌ Generating slides in parallel - slides MUST be generated one at a time in order (slide 1 → 2 → 3 ...), never concurrently

Recommended Styles for Different Contexts:

Tech product launch → glassmorphism or gradient-modern
Luxury/premium brand → dark-premium or editorial
Startup pitch → gradient-modern or minimal-swiss
Executive presentation → dark-premium or keynote
Creative agency → neo-brutalist or gradient-modern
Data/analytics → minimal-swiss or 3d-isometric
