Image Generation Skill

Generate AI-powered images using Google's Gemini image generation model. This skill is fully portable - just copy the entire folder to any project's .claude/skills/ directory.

Setup (One-time per project)

Before first use, install the skill's dependencies:

Copycd .claude/skills/image-generation && npm install && cd -

Quick Reference

Available Commands

Copy# Generate a single preset
node .claude/skills/image-generation/scripts/generate.mjs --preset hero

# Generate with specific theme combination
node .claude/skills/image-generation/scripts/generate.mjs --preset hero --theme blue --style tech

# Generate with custom prompt
node .claude/skills/image-generation/scripts/generate.mjs --prompt "Abstract flowing waves" --ratio 16:9 --output custom.png

# Generate all presets for a theme
node .claude/skills/image-generation/scripts/generate.mjs --theme teal --style fintech

# List available options
node .claude/skills/image-generation/scripts/generate.mjs --list-themes

Usage Patterns

Generate Images for Website Sections

When asked to generate website graphics:

1. Install dependencies if not already done: cd .claude/skills/image-generation && npm install && cd -
2. Determine the use case (hero, cards, accents, etc.)
3. Choose appropriate color theme based on brand
4. Choose style theme based on industry
5. Run the generation command using scripts/generate.mjs

Custom Image Generation

For custom prompts, include:

• Color palette description
• Visual elements to include
• Style/aesthetic guidance
• What to avoid (text, logos, faces)

Example:

Copynode .claude/skills/image-generation/scripts/generate.mjs \
  --prompt "Abstract geometric pattern with flowing teal gradients. Minimalist aesthetic. No text or logos." \
  --ratio 16:9 \
  --output my-image.png

Batch Generation

Generate all presets for a specific theme combination:

Copynode .claude/skills/image-generation/scripts/generate.mjs --theme purple --style tech

Custom Output Directory

Override the default output location:

Copynode .claude/skills/image-generation/scripts/generate.mjs --preset hero --output-dir ./assets/backgrounds

Output Location

The script automatically detects common image directories in this order:

1. public/images/
2. public/
3. assets/images/
4. assets/
5. images/
6. static/images/
7. static/

Falls back to creating public/images/ if none exist.

Requirements

• Node.js 18+
• AI_API_KEY environment variable in project root .env file
• Uses Google Gemini model: gemini-3-pro-image-preview

Portability

This skill is designed to be copy-pasted across projects:

1. Copy the entire .claude/skills/image-generation/ folder to new project
2. Ensure AI_API_KEY is set in the project's root .env file
3. Run cd .claude/skills/image-generation && npm install && cd -
4. Start generating images!

The script automatically:

• Finds the project root by looking for .env or package.json
• Detects the appropriate output directory
• Works with any package manager (npm, pnpm, yarn, bun)

Best Practices

1. Match theme to brand: Use color themes that align with project brand colors
2. Match style to industry: Use fintech for financial, biotech for scientific, tech for SaaS
3. Use presets first: Presets are optimized for common website sections
4. Custom prompts for special needs: Only use custom prompts when presets don't fit

Troubleshooting

If generation fails:

1. Check that AI_API_KEY is set in project root .env
2. Verify the API key is valid for Google AI
3. Ensure dependencies are installed: cd .claude/skills/image-generation && npm install
4. Check internet connectivity
5. Review the error message for specific issues
