+Initialize a new Task Master project.
+
+Arguments: $ARGUMENTS
+
+Parse arguments to determine initialization preferences.
+
+## Initialization Process
+
+1. **Parse Arguments**
+   - PRD file path (if provided)
+   - Project name
+   - Auto-confirm flag (-y)
+
+2. **Project Setup**
+   ```bash
+   task-master init
+   ```
+
+3. **Smart Initialization**
+   - Detect existing project files
+   - Suggest project name from directory
+   - Check for git repository
+   - Verify AI provider configuration
+
+## Configuration Options
+
+Based on arguments:
+- `quick` / `-y` → Skip confirmations
+- `<file.md>` → Use as PRD after init
+- `--name=<name>` → Set project name
+- `--description=<desc>` → Set description
+
+## Post-Initialization
+
+After successful init:
+1. Show project structure created
+2. Verify AI models configured
+3. Suggest next steps:
+   - Parse PRD if available
+   - Configure AI providers
+   - Set up git hooks
+   - Create first tasks
+
+## Integration
+
+If PRD file provided:
+```
+/project:tm/init my-prd.md
+→ Automatically runs parse-prd after init
+```
