Generate images with Google's Nano Banana (Gemini image generation) and save them to the project: product photos, hero banners, lifestyle shots, batches. Use for any Gemini image task. Trigger on "generate an image", "Nano Banana", "make a banner", "let's do images", "make me a picture of".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Nano Banana Image Generation Generate images using Google's Gemini Image Generation API and save them directly into the project. ## How It Works Nano Banana is Google's native image generation built into Gemini models. It accepts text prompts and returns high-quality photorealistic images. The API returns base64-encoded image data which gets decoded and saved to disk. ### Model The bundled script uses `gemini-2.5-flash-image` — Google's current image generation model. It handles product photos, hero banners, lifestyle shots, and detail close-ups well at ~$0.04/image. > **Note:** The script also accepts `--model flash` and `--model pro` for future model tiers as Google releases them. If those fail, fall back to `standard`. ### Supported Aspect Ratios - **3:4** — Product cards / catalog grid (768x1024px) - **16:9** — Hero / banner (1920x1080px) - **1:1** — Detail / texture close-ups (1024x1024px) - **4:5** — Lifestyle / editorial (1080x1350px) - Also: 1:4, 1:8, 2:3, 3:2, 4:1, 4:3, 5:4, 8:1, 9:16, 21:9 ## Setup — credential injection, never credential discovery …

How to install
mdr add ivy00johns/skill-madness/nano-banana@sha256:3880f9970669042aThe line at the top of this page pins the label v1.6.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
