Gemini画像生成APIでテキストから画像生成、既存画像の編集を行うスキル. An agent skill from minicoohei/ai-agent-camp.
- Works in 2 steps: Text-to-Image: Generate new images from… → Image Editing: Edit existing images with…
- Tasks that involve LLM API integration
- SKILL.md covers Modes, Usage, Parameters and Aspect Ratios, plus 5 more sections
- Runs Python scripts from its folder; calls python; needs GEMINI_API_KEY and GOOGLE_API_KEY
What it does
Nanobanana is an agent skill from minicoohei/ai-agent-camp. Gemini画像生成APIでテキストから画像生成、既存画像の編集を行うスキル。 「画像を生成して」「イラストを作って」「写真を編集して」等のリクエストで発動。
Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `SKILL.en.md`, `SKILL.es.md` and `agents/openai.yaml`).
It sits in Media & Creative, covering LLM API integration and Image generation. It works with Google Gemini. The repository describes itself as: AI Agent Camp — non-engineer-friendly AI agent training curriculum. Lessons, skills, commands, and hooks for Claude Code, Cursor, and Codex.
When your agent uses it
- Tasks that involve LLM API integration
- Tasks that involve Image generation
Example prompts
- “/nanobanana”
Requirements
- Python 3
- A credential in GEMINI_API_KEY
- A credential in GOOGLE_API_KEY
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Text-to-Image: Generate new images from text prompts
- Image Editing: Edit existing images with instructions
What it can do on your machine
Read from SKILL.md and the folder at commit 048ba4c. 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:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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_KEYGOOGLE_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nanobanana loads about 554 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 125 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 125 words (~554 tokens).
“Generate or edit images using Gemini Image Generation API.”
