aturilin Nano Banana Image Generator
Generate an image using Google Gemini.
User's idea: $ARGUMENTS.idea Reference image: $ARGUMENTS.ref
Important: prompt language
Write the image generation prompt in the SAME language as the user's request. If the user writes in Russian — prompt in Russian. In English — in English. Do NOT auto-translate.
Setup
Requires GEMINI_API_KEY in .env file. Get one at aistudio.google.com → API Keys → Create API key. Free tier is sufficient.
Usage
Run the script from the skill directory:
If reference image is provided:
python3 "$(dirname "$0")/nano_banana.py" -r "$ARGUMENTS.ref" "$ARGUMENTS.idea"
If no reference:
