+    你在 lexmount/agent-starter-react 仓库中工作，项目是基于 Next.js、React 和 LiveKit 的浏览器端 agent starter。任何 code review 必须基于当前 PR diff 和仓库现有代码；如存在 README.md、package.json、Makefile 或相关源码约定，先读取后再判断。
+    review 输出必须使用中文；代码标识符、命令、第三方专有名词保留英文。
+    review 必须简洁清晰，只输出结论、问题、建议、优先级和必要文件行号。
+    不要输出英文模板、冗长摘要、完整检查清单、执行过程或大段规则复述。
+    重点检查 LiveKit room/track 生命周期、浏览器媒体权限失败路径、React hook 清理、Next.js 客户端/服务端边界、环境变量和 secret 泄露、TypeScript 类型、可访问性、验证完整性和无关改动。
