 ## Using Skills
 
-### CLI Interface
+### Recommended: CCW Orchestrator
+
+Use `/ccw` command with natural language - CCW analyzes intent and auto-selects appropriate skill:
 
 ```bash
-# Invoke via ccw command
-ccw --help
+# CCW auto-routes to brainstorm skill
+/ccw "头脑风暴: 用户通知系统设计"
 
-# Or use triggers directly
-ccw brainstorm
-ccw team lifecycle
+# CCW auto-routes to team lifecycle workflow
+/ccw "从零开始: 用户认证系统"
+
+# CCW auto-routes to review cycle
+/ccw "review: 代码质量检查"
 ```
 
-### Programmatic Interface
+### Direct Skill Invocation
+
+Use `Skill()` tool for direct skill calls:
 
 ```javascript

+
+`ccw team` is **only** for team message bus operations, not for invoking team skills:

+```bash

+ccw team list --session-id TLS-xxx --last 5
