Generate or edit images using Google Nano Banana (Gemini image generation API). Trigger this skill whenever the user asks to generate an image, draw something, create artwork, edit a photo, or mentions "nano banana", "nanobanana", or any AI image generation/editing need — even if they don't explicitly mention Nano Banana. Proactively use this skill for any image creation or transformation request.
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 Skill Generate or edit images locally using the Google Gemini image generation API (a.k.a. Nano Banana). ## Quick Workflow 1. Check environment (API key + dependencies) 2. Identify the mode: text-to-image / image editing / batch generation 3. Choose the right model 4. **Use the bundled scripts directly** — no need to rewrite them 5. Run the script and save output to `/var/minis/attachments/` 6. Display the result inline in the conversation --- ## Environment Setup ### Check API Key ```bash source /etc/profile && echo $GEMINI_API_KEY | head -c 10 ``` > ⚠️ Always run `source /etc/profile` first — environment variables are stored there and won't be available otherwise. If not set, direct the user to [Google AI Studio](https://aistudio.google.com/apikey) to obtain a key, then: ```bash echo 'export GEMINI_API_KEY="your_key_here"' >> /etc/profile ``` ### Check Dependencies ```bash pip show google-genai pillow 2>&1 | grep -E "^Name|not found" ``` If missing: ```bash pip install google-genai pillow ``` --- ## Model Selection | Model | Model ID | Best For | |-------|----------|----------| …

How to install
mdr add openminis/minisskills/nano-banana@sha256:5ef6fe6c68848fb0The line at the top of this page pins the label git:20260305.3216743, 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.
