performance-profiler
快速定位前后端瓶颈并给出可执行优化建议。
某些诊断需访问生产环境或高权限工具，注意安全与隐私。
端到端性能诊断与优化，从核心指标到后端剖析。
做从前端到后端的性能诊断：Core Web Vitals（LCP、INP、CLS）、Lighthouse 审计、Bundle 分析，外加后端 CPU/内存和数据库查询剖析。用在页面加载慢、LCP 高、响应慢或想设定性能预算时，会给出具体优化点和优先级。能检测 N+1、提出缓存（Redis/CDN/HTTP）策略并结合工具（Chrome DevTools、clinic.js）给出可执行建议。

Performance profiling and optimization for web apps — Core Web Vitals (LCP, INP, CLS), Lighthouse audits, bundle analysis, backend profiling (CPU, memory, DB queries), N+1 detection, caching strategies (Redis, CDN, HTTP), and performance budgets. Use when user asks to improve performance, run Lighthouse audit, profile a Node.js app, optimize Core Web Vitals, reduce bundle size, or investigate slow response times. Do NOT use for database schema optimization (use db-sculptor), Docker image optimization (use docker), or CDN configuration.
