Nano Banana - AI Image Generation

Generate and edit images using Google Gemini models. Supports two models:

• Pro (gemini-3-pro-image-preview) — High quality, complex prompts, thinking mode
• Flash (gemini-2.5-flash-image) — Fast, cheap, good for iteration

Prerequisites

Required:

• GEMINI_API_KEY — Get from Google AI Studio
• uv (recommended) or Python 3.10+ with google-genai installed

With uv (recommended — zero setup): Dependencies are declared inline via PEP 723 and auto-installed on first run. Just use uv run instead of python3.

With pip (fallback):

pip install -r ${CLAUDE_SKILL_DIR}/requirements.txt
