 - 改 KtTable、BlogArgon、AdminAuth、QQBot、FF14Plugin、NapCatLogin、SystemLog、Knife4jSwagger、FnosK8s 前调用 `kt_component_workflow`，先看专项禁区。
 - 不确定任务边界时调用 `kt_guardrails`，先拿到“能做什么、不能做什么、怎么验证”。
 - 验证前调用 `kt_suggest_verification`，避免盲跑全量构建。
+- API/Jest 验证建议使用 `pnpm exec jest --runInBand`；指定测试文件时使用 `pnpm exec jest --runInBand --runTestsByPath test/path.spec.ts`，不要把 Jest 参数写成 `pnpm test` 的错误透传形式。
 - 页面测试前调用 `kt_create_page_test_case`，再执行 Playwright/浏览器测试。
 - Admin 页面测试前可先执行 `pnpm run admin-login -- --url <Admin登录页>` 固化登录态，输出的 `storageState` 可作为后续 Playwright 用例前置状态。
 - 接口改动后调用 `kt_api_test_plan`，并真实请求一次接口。
