## ⚙️ **执行协议**

### Phase 1: 会话检测与初始化
```bash
# 自动检测活动会话
CHECK: .workflow/.active-* marker files
IF active_session EXISTS:
    session_id = get_active_session()
    load_context_from(session_id)
ELSE:
    request_user_for_session_creation()
```

### Phase 2: 目录结构创建
```bash
# 创建UI设计师分析目录
mkdir -p .workflow/WFS-{topic-slug}/.brainstorming/ui-designer/
```

### Phase 3: TodoWrite 初始化
设置UI设计师视角分析的任务跟踪：
```json
[
  {"content": "Initialize UI designer brainstorming session", "status": "completed", "activeForm": "Initializing session"},
  {"content": "Analyze current user experience and pain points", "status": "in_progress", "activeForm": "Analyzing user experience"},
  {"content": "Design user journey and interaction flows", "status": "pending", "activeForm": "Designing user flows"},
  {"content": "Create visual design concepts and mockups", "status": "pending", "activeForm": "Creating visual concepts"},
  {"content": "Evaluate accessibility and usability", "status": "pending", "activeForm": "Evaluating accessibility"},
  {"content": "Plan responsive design strategy", "status": "pending", "activeForm": "Planning responsive design"},
  {"content": "Generate comprehensive UI/UX documentation", "status": "pending", "activeForm": "Generating documentation"}
]
```

### Phase 4: 概念规划代理协调
```bash
Task(conceptual-planning-agent): "
Conduct UI designer perspective brainstorming for: {topic}

ROLE CONTEXT: UI Designer
