A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

监控已部署 URL 是否存在回归问题。循环运行，直至手动停止或监控窗口过期。
1. HTTP 状态 — 页面是否返回 200？
2. 控制台错误 — 是否出现之前没有的新错误？
3. 网络故障 — 是否存在失败的 API 调用、5xx 响应？
4. 性能 — LCP/CLS/INP 与基线相比是否有退化？
5. 内容 — 关键元素是否消失？（h1、导航、页脚、CTA）
6. API 健康 — 关键端点是否在 SLA 内响应？快速检查（默认）：单次执行，报告结果
