# Gemini Vision API Skill This skill enables Claude to use Google's Gemini API for advanced image understanding tasks including captioning, classification, visual question answering, object detection, segmentation, and multi-image analysis. ## Quick Start ### Prerequisites 1. **Get API Key**: Obtain from [Google AI Studio](https://aistudio.google.com/apikey) 2. **Install SDK**: `pip install google-genai` (Python 3.9+) ### API Key Configuration The skill checks for `GEMINI_API_KEY` in this order: 1. **Process environment variable** (recommended) ```bash export GEMINI_API_KEY="your-api-key" ``` 2. **Skill directory**: `.claude/skills/gemini-vision/.env` ``` GEMINI_API_KEY=your-api-key ``` 3. **Project directory**: `.env` or `.gemini_api_key` in project root **Security**: Never commit API keys to version control. Add `.env` to `.gitignore`. ## Core Capabilities ### Image Analysis - **Captioning**: Generate descriptive text for images - **Classification**: Categorize and identify image content - **Visual QA**: Answer questions about image content - **Multi-image**: Compare and analyze up to 3,600 images ### Advanced Features (Model-Specific) - **Object Detection**: Identify and locate
