Nano Banana Image Generation

This skill enables AI image generation through Google's Gemini API.

Overview

The Nano Banana Image Generation skill allows agents to create images from text descriptions using Google's Gemini model. This is useful for:

• Creating concept art and visualizations
• Generating placeholder images for designs
• Producing custom graphics based on descriptions
• Rapid prototyping of visual content

Usage

To generate an image, provide a detailed text description of what you want to create.

Example Prompts

• "A futuristic cityscape at sunset with flying cars"
• "A cozy coffee shop interior with warm lighting"
• "An abstract representation of music and sound waves"

API Configuration

This skill requires a Gemini API key to function. The API key should be stored in the skill's .env file:

GEMINI_API_KEY=your_api_key_here

Getting an API Key

1. Visit Google AI Studio
2. Sign in with your Google account
3. Create a new API key
4. Copy the key and add it to the skill configuration

Best Practices

• Be specific and detailed in your image descriptions
• Include style preferences (realistic, artistic, minimalist, etc.)
• Specify desired colors, lighting, and mood
• Mention any specific elements that must be included

Limitations

• Image generation may take 30-60 seconds
• Some content types may be restricted by the API
• Results may vary based on prompt complexity
