Use this skill when users ask to generate, edit, or compose images with Nano Banana (Gemini image models), including text-to-image, image editing, multi-image composition, grounding, and output sizing/saving controls.
Do this first
Use a Node.js wrapper (@google/genai) as the primary flow (multi-turn edits, grounding, advanced generationConfig).
Use scripts/gemini-nanobanana-cli.js for quick single-turn generation/editing runs.
Do not teach raw curl; keep guidance in JS CLI/wrapper form.
Enforce these defaults
API key source: NANOBANANA_GEMINI_API_KEY with fallback GEMINI_API_KEY.
Default model: gemini-3.1-flash-image-preview (allow env override via NANOBANANA_MODEL).
Add references via repeated -i/--image (up to 14).
Enable grounding via --google-search when prompt needs fresh web context.
The API key (GEMINI_API_KEY / NANOBANANA_GEMINI_API_KEY) is injected by the workflow environment; do not hardcode it. The CLI reads it automatically from the environment.
