perf-guard
Measure REAL web performance with a budget and regression diff — runs Lighthouse CLI (mobile + desktop) or PageSpeed Insights API against a production URL, checks metrics against a perf-budget, and diffs runs. Never trusts chrome-devtools MCP traces (falsely optimistic). Use when user says "замерь перформанс", "проверь скорость сайта", "lighthouse", "core web vitals", "perf budget", "регрессия скорости", or types /perf-guard.
