Аудит производительности веб-страниц

★ 8.5 · vibe-coding

web-perf is a Claude Code skill that runs a full web performance audit using the Chrome DevTools MCP server. It measures Core Web Vitals (LCP, INP, CLS) alongside supplementary metrics — FCP, TBT, and Speed Index — and pinpoints render-blocking resources, network dependency chains, caching issues, layout shift culprits, and accessibility gaps. Audits follow a five-phase checklist: performance trace, Core Web Vitals analysis, network request inspection, accessibility snapshot, and optional codebase review. Metric thresholds and recommendations are retrieved from web.dev and Chrome DevTools documentation rather than pre-trained knowledge, keeping results accurate. The skill is the right choice when you need to profile page load, improve a Lighthouse score, or track down the specific cause of slow site performance.
