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

  • Takes a text prompt describing the desired image

  • Calls Google Gemini API with image generation configuration

  • Saves the generated image to a specified location (defaults to current directory)

  • Returns the file path for use in your project

    • Usage

    Python (Cross-Platform - Recommended)

    # 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


    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


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

    UI Assets


    User: "Generate a placeholder avatar image for the user profile component"
