+# Auto-Label Plugin
+
+Automatically labels tasks based on their description content using keyword matching. Also provides an AI agent tool for manual text classification.
+
+## Features
+
+- **Automatic Classification**: Labels tasks as they're created based on keywords in the description
+- **Multiple Categories**: Supports bug, feature, documentation, testing, refactor, and performance labels
+- **AI Agent Tool**: Provides `auto_label_classify` tool for AI agents to classify text
+- **Event Emission**: Emits `auto-label:classified` events for integration with other plugins
+
+## Installation
+
+### Option 1: Copy to plugins directory
+
+```bash
+cp -r fusion-plugin-auto-label ~/.fusion/plugins/
+```
+
+### Option 2: Install via CLI
+
+```bash
+fn plugin install /path/to/fusion-plugin-auto-label
+```
+
+## Categories
+
+The plugin classifies text into the following categories:
+
+| Category | Keywords |
+|---------|----------|
+| `bug` | bug, fix, broken, crash, error |
+| `feature` | feature, add, new, implement |
+| `documentation` | docs, documentation, readme, guide |
+| `testing` | test, testing, spec, coverage |
+| `refactor` | refactor, cleanup, clean up, reorganize |
+| `performance` | perf, performance, optimize, slow |
+
+## How It Works
+
+### Automatic Classification (onTaskCreated hook)
+
+When a task is created, the plugin:
+1. Scans the task description for keywords
+2. Matches against category rules
+3. Logs the matched labels
+4. Emits an `auto-label:classified` event with the task ID and labels
+
+### AI Agent Tool
+
+The plugin provides an `auto_label_classify` tool that AI agents can use:
+
+```javascript
+{
+  name: "auto_label_classify",
+  description: "Classify a text description into categories...",
+  parameters: {
+    type: "object",
+    properties: {
+      text: { type: "string", description: "The text to classify" }
+    },
+    required: ["text"]
+  }
+}
+```
+
+Example usage:
+```
+Use auto_label_classify with text: "Fix the login bug"
+```
+
+## Configuration
+
+This plugin has no required settings. It works out of the box with its built-in keyword rules.
+
+## Events
+
+The plugin emits the following events:
+
+| Event | Data | Description |
+|-------|------|-------------|
+| `auto-label:classified` | `{ taskId, labels }` | Emitted when a task is classified |
+
+## Development
