Performance Benchmark captures page performance metrics (TTFB, FCP, LCP, DOM timings, resource sizes), stores baselines, compares current runs against baselines, and generates regression reports with actionable recommendations. It supports per-page audits, diff-based runs for PRs, trend analysis, and performance budgets.
Use this skill when you want to: capture a baseline before a large change, validate that a PR doesn't regress Core Web Vitals, run quick timing checks, or produce trend reports across historical runs. Common triggers include manual audits, CI checks on PRs, and periodic performance monitoring.
Likely compatible with Claude Code / browse daemon based agents and CLI-driven automation (benchmarks rely on the browse daemon and shell tools).
