What it does
Nano Banana Pro is an agent skill from swarmclawai/swarmclaw. Generate or edit images via Gemini 3 Pro Image (Nano Banana Pro). Use when asked to create, generate, or edit images and a Gemini API key is available. Supports text-to-image generation, single-image editing, and multi-image composition (up to 14 images).
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/generate_image.py`).
It sits in Media & Creative, covering Image generation, Image editing and LLM API integration. It works with Google Gemini and Model Context Protocol. The repository describes itself as: Open-source self-hosted AI agent runtime and multi-agent framework for autonomous agent swarms. Agent memory, MCP tools, schedules, delegation, and 23+ LLM providers (Claude… The licence is MIT.
When your agent uses it
- Asked to create
- Edit images and a Gemini API key is available
Example prompts
- “/nano-banana-pro”
Requirements
- Python 3
- A credential in GEMINI_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit ed38ba5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
GEMINI_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nano Banana Pro loads about 481 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 88 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- Generate or edit images via Gemini 3 Pro Image (Nano Banana Pro). Use when asked to create, generate, or edit images and a Gemini API key is available. Supports text-to-image generation, single-image editing, and multi-image composition (up to 14 images).
Nano Banana Pro (Gemini 3 Pro Image)
Use the bundled script to generate or edit images.
Generate
uv run {baseDir}/scripts/generate_image.py --prompt "your image description" --filename "output.png" --resolution 1KEdit (Single Image)
uv run {baseDir}/scripts/generate_image.py --prompt "edit instructions" --filename "output.png" -i "/path/in.png" --resolution 2KMulti-Image Composition (up to 14 images)
uv run {baseDir}/scripts/generate_image.py --prompt "combine these into one scene" --filename "output.png" -i img1.png -i img2.png -i img3.pngAPI Key
Set GEMINI_API_KEY as an environment variable, or pass --api-key <KEY> to the script.
Aspect Ratio (optional)
uv run {baseDir}/scripts/generate_image.py --prompt "portrait photo" --filename "output.png" --aspect-ratio 9:16Notes
- Resolutions:
1K(default),2K,4K. - Aspect ratios:
1:1,2:3,3:2,3:4,4:3,4:5,5:4,9:16,16:9,21:9. Without--aspect-ratio, the model picks freely. - Use timestamps in filenames for uniqueness:
yyyy-mm-dd-hh-mm-ss-name.png. - Do not read the image back into context; report the saved path only.
