 - Use MCP to connect at `http://10.1.1.104:9222` (SSH forwarded DevTools port).
 - Open target URLs via MCP and run page-level assertions (no API-level calls required).
 
+## AI Auto-Handling Prereqs
+
+- **Seed 检查/执行**
+  - DB 查询（示例）：`SELECT COUNT(*) FROM tenants;`
+  - 若结果为 0，执行 `go run ./backend/main.go seed` 后再继续。
+- **tenantCode 获取**
+  - DB 查询：`SELECT code FROM tenants ORDER BY id DESC LIMIT 1;`
+  - 将结果注入到 Portal URL `/t/:tenantCode`。
+- **清理浏览器存储**
+  - 在 MCP 中执行脚本：清理 `localStorage` / `sessionStorage`，并清除 cookies。
+  - 示例：`chrome-devtools_evaluate_script` → `() => { localStorage.clear(); sessionStorage.clear(); document.cookie.split(';').forEach(c => document.cookie = c.replace(/^ +/, '').replace(/=.*/, '=;expires=' + new Date().toUTCString() + ';path=/')); }`
+
 ### MCP Example Flow (AI Guidance)
