使用此技能在部署、合并或依赖升级后监控已部署的URL是否存在回归问题。
d8409a4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
/canary-watch https://myapp.com
持续监控:每 N 分钟检查一次,持续 M 小时
/canary-watch https://myapp.com --interval 5m --duration 2h
差异模式:对比预发布环境与生产环境
/canary-watch --compare https://staging.myapp.com https://myapp.com
critical: # immediate alert
- HTTP status != 200
- Console error count > 5 (new errors only)
- LCP > 4s
- API endpoint returns 5xx
warning: # flag in report
- LCP increased > 500ms from baseline
- CLS > 0.1
- New console warnings
- Response time > 2x baseline
info: # log only
- Minor performance variance
- New network requests (third-party scripts added?)
当超过关键阈值时:

### 未检测到回归问题。部署状态良好。
