What it does
Nanobanana Skill is an agent skill from feiskyer/codex-settings. Generate, edit, or composite images with Gemini/Nanobanana. Default for image requests without a named provider; do not override a different provider the user chose.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `agents/openai.yaml`, `nanobanana.py` and `tests/test_nanobanana.py`).
It works with Google Gemini. The repository describes itself as: Curated skills, profiles, and config templates that supercharge Codex CLI — multi-model, deep research, image gen & browser automation. The licence is MIT.
Example prompts
- “/nanobanana-skill”
Requirements
- Python 3
- A credential in GEMINI_API_KEY
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- GEMINI_API_KEY in ~/.nanobanana.env (GEMINI_API_KEY=sk-dummy) or the shell environment.
- Python dependencies from requirements.txt.
- The executable is nanobanana.py in this same skill directory. Resolve its absolute path once before running it.
What it can do on your machine
Read from SKILL.md and the folder at commit d7f6570. 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 script files (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
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_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nanobanana Skill loads about 1.2k tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 459 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.

- description
- Generate, edit, or composite images with Gemini/Nanobanana. Default for image requests without a named provider; do not override a different provider the user chose.
Nanobanana Image Skill
Use the bundled nanobanana.py to generate or edit images with Gemini image models. The default path targets Nano Banana 2 (gemini-3.1-flash-image-preview) with thinking summaries and Google Search grounding on, because those defaults are the main reason to use this skill instead of a generic image prompt.
Requirements
GEMINI_API_KEYin~/.nanobanana.env(GEMINI_API_KEY=sk-dummy) or the shell environment.- Python dependencies from
requirements.txt. - The executable is
nanobanana.pyin this same skill directory. Resolve its absolute path once before running it.
The CLI can print --help without credentials. It validates local input files before creating an API client and exits non-zero when the API returns no image.
Defaults
Model gemini-3.1-flash-image-preview, search grounding on, thinking summaries on at level high, resolution 1K, and no aspect ratio unless the request implies a shape. Do not make the user choose a model, search mode, or thinking mode unless they asked for that level of control.
Leaving aspect ratio unspecified is usually better for edits, because Gemini can match the input image shape. For text-only generation, set one only when the user implies a format such as poster, square post, banner, phone wallpaper, or ultrawide hero.
Worth overriding: --model gemini-3-pro-image-preview for very detail-heavy or typography-sensitive work (slower); --resolution 512px for quick ideation (Nanobanana 2 models only), 2K/4K for polished deliverables; --thinking-level low when latency beats refinement; search off when the user wants a purely imaginative result. Run python3 /absolute/path/to/nanobanana.py --help for the exact accepted values, including the full aspect-ratio and model lists.

Run it
Generate from text:
python3 /absolute/path/to/nanobanana.py \
--prompt "Create a high-end coffee bag package design with tactile paper texture and clear typography" \
--output /absolute/path/to/output/package.pngEdit or composite — pass every reference with --input. Nanobanana 2 mixes multiple references well, so do not narrow a blend, lineup, storyboard, or consistency pass down to a single image:
python3 /absolute/path/to/nanobanana.py \
--prompt "Turn these product photos into a clean ecommerce hero image with a soft studio shadow and subtle headline area" \
--input /absolute/path/to/ref1.png /absolute/path/to/ref2.png \
--aspect-ratio 4:5 \
--output /absolute/path/to/output/hero.pngGrounded generation, saving the model's text and metadata alongside the image:
python3 /absolute/path/to/nanobanana.py \
--prompt "Use Google Search to ground an editorial illustration about the most recent lunar mission and create a clean magazine cover concept" \
--text-output /absolute/path/to/output/cover.txt \
--metadata-output /absolute/path/to/output/cover.json \
--output /absolute/path/to/output/cover.pngThen report the saved path(s), whether search grounding stayed enabled, where any text or thought summaries landed, and any warning from the run. If the model returns text but no image, say so plainly and suggest a more explicitly image-focused prompt rather than presenting the run as a success.
Prompting
Good Nanobanana prompts are production briefs, not art wishes: subject, visual style, composition or camera framing, any required text, the output's use case, and constraints such as brand colors, negative space, or realism level.
Create a premium sparkling water can advertisement. Use a cold studio product-photo look, silver highlights, condensation droplets, and a clean dark-teal background. Leave negative space in the upper-right for headline copy.For edits, say what to preserve as well as what to change:
Keep the shoe silhouette and logo placement intact. Replace the background with a bright outdoor basketball court, add dynamic afternoon shadows, and keep the image looking like a real sports campaign photo.When a run fails
Check credential presence without printing its value, input readability, and output writability. For an unsupported option, consult the helper's accepted values. Correct assistant-chosen options within the requested result, but do not silently switch a user-selected model or provider. Before a bounded retry, check whether the earlier attempt already produced output; report the actual error if recovery would require new authority or changing the request.
