Use when the user asks to generate or edit images with Nano Banana, Gemini image models, `gemini-3.1-flash-image-preview`, `gemini-3-pro-image-preview`, or says things like “用 Gemini 出图”, “用 Nano Banana 生成图片”, “改图”, “多张变体”, “海报/插画/图标”. Prefer the bundled CLI at `scripts/nanobanana.py` instead of ad-hoc requests.

Nano Banana Skill
Use this skill for Gemini image generation and lightweight image editing through Nano Banana models.
When to use
- The user explicitly mentions
nanobanana,Nano Banana, Gemini image generation, or a Gemini image model name - The user wants to generate one or more images from a prompt
- The user wants to generate images based on one or more reference images
- The user wants to edit an existing image with a text instruction
Workflow
- Decide whether this is
generateoredit. - Check that one of these environment variables is set:
NANOBANANA_API_KEY,GEMINI_API_KEY,GOOGLE_API_KEY. - Run the bundled script:
- Generate:
python3 scripts/nanobanana.py generate --prompt "..." --out output/nanobanana/result.png - Generate with references:
python3 scripts/nanobanana.py generate --prompt "..." --reference ref1.png --reference ref2.jpg - Edit:
python3 scripts/nanobanana.py edit --input path/to/input.png --prompt "..." --out output/nanobanana/result.png
- Generate:
- If the user asks for multiple variants, add
--count N. - If the user provides one or more reference images, pass them with repeated
--reference. - If the user asks for Pro quality, add
--model gemini-3-pro-image-preview. - If the user wants the result to pop open automatically, add
--preview. - Return the output path and, when helpful, show the generated image in the response.
Defaults
- Default model:
gemini-3.1-flash-image-preview - Default output format:
png - Default output directory when
--outis omitted:output/nanobanana/ editaccepts repeated--inputso multiple source images can be combined in one request
Proxy notes
- If the machine relies on a local proxy, keep
HTTP_PROXYandHTTPS_PROXYin the environment before running the script. - If needed, set
NANOBANANA_PROXY_URLexplicitly. - If neither proxy variable is set, the script will try a few common local proxy ports as a fallback.
Rules
- Prefer the bundled script over handwritten
curlrequests. - Do not ask the user to paste API keys into chat.
- For edits, preserve the original image unless the user explicitly asks to overwrite it.
- If generation fails, surface the exact API error message and suggest switching model or checking key/project status.
Examples
python3 scripts/nanobanana.py generate \
--prompt "a minimalist travel poster of Hangzhou West Lake at sunrise" \
--out output/nanobanana/west-lake.png
python3 scripts/nanobanana.py generate \
--prompt "three flat vector app icons for a note-taking app" \
--count 3 \
--model gemini-3-pro-image-preview \
--out output/nanobanana/notes.png
python3 scripts/nanobanana.py generate \
--prompt "create a mascot sticker based on the banana reference, with a playful black outline" \
--reference assets/banana.png \
--preview
python3 scripts/nanobanana.py edit \
--input assets/photo.png \
--prompt "replace the background with a clean warm beige studio backdrop" \
--out output/nanobanana/photo-edit.png
python3 scripts/nanobanana.py edit \
--input assets/product-front.png \
--input assets/product-side.png \
--prompt "combine these into one clean e-commerce hero image on a white background" \
--preview

Use when work should span one or more detached tasks but still behave like one job with a single owner context. TaskFlow is the durable flow substrate under authoring layers like Lobster, ACPX, plugins, or plain code. Keep conditional logic in the caller; use TaskFlow for flow identity, child-task linkage, waiting state, revision-checked mutations, and user-facing emergence.
