Imagen - AI Image Generation Skill

Overview

This skill generates images using Google Gemini's image generation model (gemini-3-pro-image-preview). It enables seamless image creation during any Claude Code session - whether you're building frontend UIs, creating documentation, or need visual representations of concepts.

Cross-Platform: Works on Windows, macOS, and Linux.

When to Use This Skill

Automatically activate this skill when:

  • •User requests image generation (e.g., "generate an image of...", "create a picture...")
  • •Frontend development requires placeholder or actual images
  • •Documentation needs illustrations or diagrams
  • •Visualizing concepts, architectures, or ideas
  • •Creating icons, logos, or UI assets
  • •Any task where an AI-generated image would be helpful

How It Works

  1. •Takes a text prompt describing the desired image
  2. •Calls Google Gemini API with image generation configuration
  3. •Saves the generated image to a specified location (defaults to current directory)
  4. •Returns the file path for use in your project

Usage

Python (Cross-Platform - Recommended)

bash
# Basic usage
python scripts/generate_image.py "A futuristic city skyline at sunset"

# With custom output path
python scripts/generate_image.py "A minimalist app icon for a music player" "./assets/icons/music-icon.png"

# With custom size
python scripts/generate_image.py --size 2K "High resolution landscape" "./wallpaper.png"

Requirements

  • •GEMINI_API_KEY environment variable must be set
  • •Python 3.6+ (uses standard library only, no pip install needed)

Output

Generated images are saved as PNG files. The script returns:

  • •Success: Path to the generated image
  • •Failure: Error message with details

Examples

Frontend Development

code
User: "I need a hero image for my landing page - something abstract and tech-focused"
-> Generates and saves image, provides path for use in HTML/CSS

Documentation

code
User: "Create a diagram showing microservices architecture"
-> Generates visual representation, ready for README or docs

UI Assets

code
User: "Generate a placeholder avatar image for the user profile component"
-> Creates image in appropriate size for component use
