Slide Creator

This skill transforms written content into visual slide deck images using AI image generation. It analyzes text content, extracts key points, and generates presentation-quality slide images.

Prerequisites

• The nano-banana skill must be available for image generation.
• Python 3.10+
• google-genai package installed

Workflow Overview

1. Input: Receive content (blog post, article, newsletter, outline)
2. Analysis: Extract key points and structure
3. Outline: Create slide outline with titles and talking points
4. Generation: Create image prompts and generate slide images
5. Refinement: Accept feedback and regenerate specific slides

Creating Slides from Content

Step 1: Analyze the Content

Read and analyze the source content to identify:

• Main topic/theme
• Key sections or chapters
• Important points to visualize
• Logical flow and transitions

Step 2: Create Slide Outline

Structure the presentation as:

Slide 1: Title slide (topic, subtitle)
Slide 2: Introduction/Problem statement
Slides 3-N: Key points (one concept per slide)
Slide N+1: Conclusion/Summary
Slide N+2: Call to action (optional)

Step 3: Generate Image Prompts

For each slide, create an image prompt that:

• Captures the key concept visually
• Uses consistent style across all slides
• Leaves appropriate space for text overlay
• Matches the desired aspect ratio (typically 16:9)

Step 4: Generate Slide Images

Use the nano-banana skill to generate images:

# Single slide
python ~/.claude/skills/nano-banana/scripts/generate_image.py \
    "Professional slide background: [concept], [style], 16:9 aspect, clean with text space" \
    slide_01.png --aspect 16:9

# Batch generation
python ~/.claude/skills/nano-banana/scripts/batch_generate.py \
    slide_prompts.json ./slides/ --aspect 16:9 --parallel 3

Step 5: Refinement

Accept feedback and regenerate specific slides:

# Edit existing slide
python ~/.claude/skills/nano-banana/scripts/edit_image.py \
    slides/slide_03.png "make the colors more vibrant" slides/slide_03_v2.png

Slide Prompt Patterns

Title Slide

Bold typography-inspired background for [topic] presentation, [style], gradient [colors], modern and professional, 16:9 aspect ratio

Concept Slide

Visual metaphor for [concept]: [metaphor description], [style], [brand colors], clean composition with space on [left/right] for text overlay, presentation graphic

Data/Stats Slide

Abstract data visualization representing [metric/trend], infographic style, [colors], clean white background, professional presentation graphic

Transition/Section Slide

Section divider for [section name], abstract [theme] imagery, gradient [colors], full bleed background, minimal text space

Conclusion Slide

Inspiring background for conclusion: [theme], uplifting atmosphere, [colors], professional, space for summary points

Style Presets

See references/slide-styles.md for pre-defined style presets:

• Corporate: Professional blues, clean lines, minimal
• Creative: Bold colors, dynamic compositions
• Technical: Dark theme, code/circuit aesthetics
• Minimalist: White space, subtle accents
• Warm: Earth tones, organic shapes

Batch Generation Format

Create a slide_prompts.json file:

[
    {
        "prompt": "Title slide for AI presentation, modern tech aesthetic, blue gradient, bold composition",
        "filename": "slide_01_title.png",
        "aspect": "16:9"
    },
    {
        "prompt": "Visual metaphor: neural network as interconnected nodes, tech illustration style, blue and purple",
        "filename": "slide_02_intro.png",
        "aspect": "16:9"
    },
    {
        "prompt": "Growth chart concept, abstract rising bars with glow effect, tech presentation style",
        "filename": "slide_03_growth.png",
        "aspect": "16:9"
    }
]

# The Future of Remote Work

Remote work is transforming how we think about productivity...

## Key Benefits
1. Flexibility
2. Work-life balance
3. Global talent access

## Challenges
- Communication
- Culture building
- Technology needs

## Best Practices
...

Generated Slide Outline

1. Title: "The Future of Remote Work"
2. Hook: Remote work transformation visual
3. Benefits: Flexibility metaphor
4. Benefits: Work-life balance visual
5. Benefits: Global connectivity
6. Challenges: Communication barriers
7. Solutions: Best practices overview
8. Conclusion: Future outlook

Generated Prompts

[
    {"prompt": "Title slide: Future of Remote Work, modern office fading into home workspace, professional blue tones", "filename": "slide_01.png"},
    {"prompt": "Remote work transformation: office desk morphing into laptop anywhere, clean illustration style", "filename": "slide_02.png"},
    {"prompt": "Flexibility concept: person working from beach, mountain, city cafe montage, lifestyle photography style", "filename": "slide_03.png"}
]

Tips for Quality Slides

1. Consistency: Use same style keywords across all prompts.
2. Text Space: Always include "space for text" or "clean area for overlay".
3. Aspect Ratio: Use 16:9 for standard presentations.
4. One Concept: Each slide should visualize ONE key point.
5. Color Harmony: Establish a palette and reference it in each prompt.

Feedback Handling

When the user requests changes:

1. Specific slide: Regenerate just that slide with modified prompt.
2. Style change: Create new prompts and batch regenerate all.
3. Minor edits: Use edit_image.py for adjustments.
4. Iterative: Use chat_session.py for complex refinements.
