Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
6 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by cnemri on GitHub. Read the source before you install it.

Installation

Install the Nano Banana Build AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/cnemri/google-genai-skills/tree/main/skills/nano-banana-build
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/cnemri/google-genai-skills.git /tmp/google-genai-skills
mkdir -p .claude/skills
cp -r /tmp/google-genai-skills/skills/nano-banana-build .claude/skills/nano-banana-build

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Nano Banana Build in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Nano Banana Build on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Nano Banana Build is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Nano Banana Image Generation Skill

Use this skill to generate and edit images using the google-genai Python SDK with Gemini's specialized image models (Nano Banana).

Quick Start Setup

python
from google import genai
from google.genai import types
from PIL import Image
import io

client = genai.Client()

Reference Materials

Model Capabilities: Comparison of Gemini 2.5 vs 3 Pro, resolutions, and token costs.
Image Generation: Text-to-Image, Interleaved Text/Image.
Image Editing: Subject Customization, Style Transfer, Multi-turn Editing.
Thinking Process: Understanding thoughts and signatures (Gemini 3 Pro).
Recipes: Extensive collection of examples (Logos, Stickers, Mockups, Comics, etc.).
Source Code: Deep inspection of SDK internals.

Available Models

gemini-2.5-flash-image (Nano Banana): Fast, high-quality generation and editing. Best for most use cases.
gemini-3-pro-image-preview (Nano Banana Pro): Highest fidelity, supports 2K and 4K resolution, complex prompt adherence, and grounding.

Common Workflows

1. Fast Generation

python
response = client.models.generate_content(
    model='gemini-2.5-flash-image',
    contents='A cute robot eating a banana',
    config=types.GenerateContentConfig(
        response_modalities=['IMAGE']
    )
)

2. High-Quality Editing

python
response = client.models.generate_content(
    model='gemini-3-pro-image-preview',
    contents=[
        types.Part.from_uri(file_uri='gs://.../shoe.jpg', mime_type='image/jpeg'),
        "Change the color of the shoe to neon green."
    ],
    config=types.GenerateContentConfig(response_modalities=['IMAGE'])
)

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Nano Banana Build AI skill do?

Generate and edit high-quality images using Gemini 2.5 Flash Image and Gemini 3 Pro Image (Nano Banana). Supports Text-to-Image, Style Transfer, Virtual Try-On, and Character Consistency.

Why use Nano Banana Build on TypingMind?

Because you install it once and use it with any model. Nano Banana Build is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Nano Banana Build in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/cnemri/google-genai-skills/tree/main/skills/nano-banana-build. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Nano Banana Build?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Nano Banana Build?

As many as you like. As long as a model supports skills, you can use Nano Banana Build with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Nano Banana Build AI skill free?

Yes. It is published on GitHub by cnemri under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
