Nano Banana 2 Image Generation & Editing

Generate new images or edit existing ones using the grsai.com Nano Banana 2 API.

Usage

Run the script using absolute path (do NOT cd to skill directory first):

Generate new image:

uv run scripts/generate_image.py --prompt "your image description" --filename "output-name.png" [--resolution 1K|2K|4K] [--api-key KEY] [--no-enhance]

Edit existing image:

uv run scripts/generate_image.py --prompt "editing instructions" --filename "output-name.png" --input-image "path/to/input.png" [--resolution 1K|2K|4K] [--api-key KEY] [--no-enhance]

Important: Always run from the user's current working directory so images are saved where the user is working, not in the skill directory.
