This Skill detects performance regressions in web pages by measuring real page-load and Core Web Vitals data before and after each change, so slowdowns are caught early instead of discovered by users.
Run /benchmark https://example.com --baseline to capture your current performance baseline, then run /benchmark https://example.com to compare and highlight regressions.

Catch web performance regressions by benchmarking web pages to capture real navigation metrics and Core Web Vitals, then comparing current results against a stored baseline to flag slowdowns before release.
Set up a performance baseline for PR checks by running a benchmark command with the baseline flag on your target URL, which saves the initial navigation timings and Core Web Vitals data for future comparison.
You can analyze JavaScript bundle size and resource load times during a performance audit because the benchmarking process summarizes top slow resources alongside JS and CSS transfer volume to pinpoint causes of regressions.
Core Web Vitals trend analysis is supported by aggregating historical baseline data into reports, showing whether your overall web page performance metrics are improving or degrading across multiple routes over time.
The best way to automate page speed monitoring for multiple routes is using script-driven extraction of performance entries via a deterministic browse daemon, generating baseline and diff reports for each route automatically.
You need a deterministic page measurement environment for performance benchmarking because the browse daemon ensures consistent script-driven extraction of Core Web Vitals and resource size data, preventing flaky metrics from masking real regressions.
