Generate images from a text prompt via OpenRouter's image generation API (Nano Banana / Gemini Flash Image). Displays the result inside the widget and saves to disk for download.
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 widget An extension skill that renders a generator inside the **Widgets** tab. Type a prompt, pick a model, press **Generate**, and the image appears directly in the card. From v0.2.0 the image is also **saved to disk** and a **Download image** button appears below it. Backed by OpenRouter's image generation endpoint. Two Google models available: the default is **Nano Banana** (`google/gemini-3.1-flash-image-preview`). ## Persistence and download (v0.2.0) From v0.2.0, every generation saves the image to the skill's private state directory: `~/Ouroboros/data/state/skills/nanobanana/img_<12 hex chars>.<ext>`. Two separate routes serve the image: - `GET /api/extensions/nanobanana/media?image_id=...` — **inline** preview (Content-Disposition: inline), used by the `<img>` tag in the widget. - `GET /api/extensions/nanobanana/download?image_id=...` — **attachment** download, sets proper filename so the file saves as `img_<hex>.png`. Neither route requires the `OPENROUTER_API_KEY` grant — they serve files already written to disk. A generated image stays accessible even if you later revoke the generation grant. ## Setup …

How to install
mdr add razzant/ouroboroshub/nanobanana@sha256:c39455f61fe09494The line at the top of this page pins the label v0.2.4, 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.
