Equip Claude Code with Nano Banana — give Claude the power to generate and edit images.

This is a Claude Code skill that integrates Google Gemini's Nano Banana image models, enabling Claude to generate images from text, edit existing images, iteratively refine images through multi-turn conversation, and output in 2K/4K resolution.

Go to Google AI Studio to create your API key.

Important: Nano Banana models do NOT support the free tier. You must bind a credit card and upgrade to a paid plan to use the image generation API.

Add your API key to ~/.zshrc or ~/.bashrc:

export GEMINI_API_KEY="your-api-key-here"

pip install google-genai Pillow

Clone this repo into Claude Code's skills directory:

git clone https://github.com/haotongl/gemini-image-skill.git ~/.claude/skills/gemini-image

Restart Claude Code and you're good to go.

Once installed, just talk to Claude Code in natural language:

> Draw a cyberpunk cat sitting on the moon

> Change the background of this image to a starry sky  (drag in an image or specify a path)

> Make the colors brighter, add a glow effect  (multi-turn iteration)

> Generate the final version in 2K HD

If you're behind a proxy, set the environment variables in your shell config (~/.zshrc or ~/.bashrc):

export http_proxy="http://your-proxy:port"
export https_proxy="http://your-proxy:port"
