Nanobanana Image Generation Skill
Generate or edit images using Google Gemini API through the nanobanana tool.
Requirements
GEMINI_API_KEY: Must be configured in ~/.nanobanana.env or export GEMINI_API_KEY=<your-api-key> Python3 with depedent packages installed: google-genai, Pillow, python-dotenv. They could be installed via python3 -m pip install -r ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/requirements.txt if not installed yet. Executable: ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/nanobanana.py
For image generation
Ask the user for: What they want to create (the prompt) Desired aspect ratio/size (optional, defaults to 9:16 portrait) Output filename (optional, auto-generates UUID if not specified) Model preference (optional, defaults to gemini-3-pro-image-preview) Resolution (optional, defaults to 1K) Run the nanobanana script with appropriate parameters: python3 ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/nanobanana.py --prompt "description of image" --output "filename.png" Show the user the saved image path when complete
For image editing
Ask the user for: Input image file(s) to edit What changes they want (the prompt) Output filename (optional) Run with input images: python3 ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/nanobanana.py --prompt "editing instructions" --input image1.png image2.png --output "edited.png"
Aspect Ratios (--size)
1024x1024 (1:1) - Square 832x1248 (2:3) - Portrait 1248x832 (3:2) - Landscape 864x1184 (3:4) - Portrait 1184x864 (4:3) - Landscape 896x1152 (4:5) - Portrait 1152x896 (5:4) - Landscape 768x1344 (9:16) - Portrait (default) 1344x768 (16:9) - Landscape 1536x672 (21:9) - Ultra-wide
Models (--model)
gemini-3-pro-image-preview (default) - Higher quality gemini-2.5-flash-image - Faster generation
Resolution (--resolution)
1K (default) 2K 4K
Generate a simple image
python3 ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/nanobanana.py --prompt "A serene mountain landscape at sunset with a lake"
Generate with specific size and output
python3 ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/nanobanana.py \ --prompt "Modern minimalist logo for a tech startup" \ --size 1024x1024 \ --output "logo.png"
Generate landscape image with high resolution
python3 ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/nanobanana.py \ --prompt "Futuristic cityscape with flying cars" \ --size 1344x768 \ --resolution 2K \ --output "cityscape.png"
Edit existing images
python3 ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/nanobanana.py \ --prompt "Add a rainbow in the sky" \ --input photo.png \ --output "photo-with-rainbow.png"
Use faster model
python3 ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/nanobanana.py \ --prompt "Quick sketch of a cat" \ --model gemini-2.5-flash-image \ --output "cat-sketch.png"
Error Handling
If the script fails: Check that GEMINI_API_KEY is exported or set in ~/.nanobanana.env Verify input image files exist and are readable Ensure the output directory is writable If no image is generated, try making the prompt more specific about wanting an image
Best Practices
Be descriptive in prompts - include style, mood, colors, composition For logos/graphics, use square aspect ratio (1024x1024) For social media posts, use 9:16 for stories or 1:1 for posts For wallpapers, use 16:9 or 21:9 Start with 1K resolution for testing, upgrade to 2K/4K for final output Use gemini-3-pro-image-preview for best quality, gemini-2.5-flash-image for speed
