 Here is a quick example of a common development workflow:
 
+### **Option 1: Lite-Plan Workflow** (⚡ Recommended for Quick Tasks)
+
+Lightweight interactive workflow with in-memory planning and immediate execution:
+
+```bash
+# Basic usage with auto-detection
+/workflow:lite-plan "Add JWT authentication to user login"
+
+# Force code exploration
+/workflow:lite-plan -e "Refactor logging module for better performance"
+
+# Preset CLI tool
+/workflow:lite-plan --tool codex "Add unit tests for auth service"
+```
+
+**Interactive Flow**:
+1. **Phase 1**: Automatic task analysis and smart code exploration (if needed)
+2. **Phase 2**: Answer clarification questions (if any)
+3. **Phase 3**: Review generated plan with task breakdown
+4. **Phase 4**: Three-dimensional confirmation:
+   - ✅ Confirm/Modify/Cancel task
+   - 🔧 Choose execution: Agent / Provide Plan / CLI (Gemini/Qwen/Codex)
+   - 🔍 Optional code review: No / Claude / Gemini / Qwen / Codex
+5. **Phase 5**: Watch real-time execution with live task tracking
+
+### **Option 2: Full Workflow** (Comprehensive Planning)
+
+Traditional multi-phase workflow for complex projects:
+
 1.  **Create a Plan** (automatically starts a session):
     ```bash
     /workflow:plan "Implement JWT-based user login and registration"
