## ⚙️ **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
# 创建安全专家分析目录
mkdir -p .workflow/WFS-{topic-slug}/.brainstorming/security-expert/
```

### Phase 3: TodoWrite 初始化
设置安全专家视角分析的任务跟踪：
```json
[

  {"content": "Conduct threat modeling and risk assessment", "status": "in_progress", "activeForm": "Conducting threat modeling"},
  {"content": "Design security architecture and controls", "status": "pending", "activeForm": "Designing security architecture"},
  {"content": "Evaluate compliance requirements", "status": "pending", "activeForm": "Evaluating compliance"},
  {"content": "Plan incident response and monitoring", "status": "pending", "activeForm": "Planning incident response"},
  {"content": "Assess data protection and privacy", "status": "pending", "activeForm": "Assessing data protection"},
  {"content": "Generate comprehensive security documentation", "status": "pending", "activeForm": "Generating documentation"}
]
```

### Phase 4: 概念规划代理协调
```bash
Task(conceptual-planning-agent): "
