+# Gemini Image Tools
+
+This collection of tools allows you to edit and analyze images using Google's Gemini AI directly from OpenCode.
+
+## Setup
+
+1. Get your Gemini API key from [Google AI Studio](https://makersuite.google.com/app/apikey)
+2. Add it to your `.env` file:
+   ```bash
+   GEMINI_API_KEY=your_api_key_here
+   ```
+
+## Available Tools
+
+### `/gemini` - Simple Image Editor
+Edit an image using file path or data URL:
+
+```bash
+/gemini "path/to/image.png" "Add a red border around the image" "output.png"
+/gemini "data:image/png;base64,AAA..." "Convert to black and white"
+```
+
+### `/gemini_multiple_edit` - Advanced Image Editor
+Same functionality as `/gemini` but from the multiple tools file:
+
+```bash
+/gemini_multiple_edit "image.jpg" "Make it look like a watercolor painting" "watercolor.jpg"
+```
+
+### `/gemini_multiple_analyze` - Image Analysis
+Analyze an image without editing it:
+
+```bash
+/gemini_multiple_analyze "screenshot.png" "What programming language is shown in this code?"
+/gemini_multiple_analyze "photo.jpg" "Describe the objects and colors in this image"
+```
+
+### `/gemini_edit` - Auto-Detection Plugin
+1. Paste an image directly into your OpenCode chat
+2. Use the command with just the prompt:
+
+```bash
+/gemini_edit "Add the text 'Hello World' in cursive at top"
+/gemini_edit "Make this image look like a painting"
+```
+
+## Features
+
+- **File Path Support**: Pass local image file paths
+- **Data URL Support**: Use base64 data URLs from pasted images
+- **Auto-Detection**: Plugin automatically captures the latest pasted image
+- **Image Analysis**: Ask questions about images without editing
+- **Flexible Output**: Specify custom output filenames or use defaults
+- **Error Handling**: Clear error messages for missing API keys or failed requests
+
+## Files
+
+- `gemini.ts` - Simple tool that accepts image arguments
+- `gemini-multiple.ts` - Multiple tools (edit + analyze) in one file
+- `../plugin/gemini-edit.ts` - Plugin with auto-detection of pasted images
+
+## API Endpoints
+
+- **Image Editing**: Uses Gemini 2.5 Flash with image preview capabilities
+- **Image Analysis**: Uses Gemini 2.5 Flash for text-based analysis
+
+## Examples
+
+```bash
+# Edit an image
+/gemini "logo.png" "Add a subtle drop shadow" "logo-shadow.png"
+
+# Analyze code in a screenshot
+/gemini_multiple_analyze "code-screenshot.png" "What bugs can you spot in this code?"
+
+# Auto-edit pasted image
+# (paste image first, then run:)
+/gemini_edit "Remove the background and make it transparent"
+```
