What it does
Nano Banana Pro is an agent skill from refly-ai/refly-skills. Generate or edit images via Gemini 3 Pro Image (Nano Banana Pro). Use when you need to: (1) generate images from text descriptions, (2) edit existing images with AI, (3) compose multiple images into one scene. Supports 1K/2K/4K resolutions and up to 14 input images for composition.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Media & Creative, covering Image generation and Image editing. It works with Google Gemini. The repository describes itself as: Refly skills repository.
When your agent uses it
- Generate images from text descriptions
- Edit existing images with AI
- Compose multiple images into one scene
Example prompts
- “/nano-banana-pro”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- (Optional): Upload Input Image
- Run the Skill and Get Run ID
- Open Workflow in Browser and Wait for Completion
- Download and Show Result
What it can do on your machine
Read from SKILL.md and the folder at commit 5a546d2. 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
Shell commands in SKILL.md call:
jq
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
refly.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nano Banana Pro loads about 1.2k tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 234 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); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 234 words (~1,190 tokens).
