Use when the user wants to run local web quality tests: "本地测试", "playwright 测试", "跑测试", "测试页面", "lighthouse 审计", "性能测试", "验证修复", "check accessibility", "check performance". Works with any web project (Next.js, Vite, Nuxt, etc.). Uses Playwright MCP for DOM rule checks (image format, lazy loading, external link security, aria-hidden on animated elements) and Chrome Lighthouse CLI for performance/accessibility scores. Adapts build command and output directory to the current project. Outputs a pass/fail table.
