Web applications gradually degrade in performance through small, cumulative changes that are difficult to detect until users complain. This Skill establishes performance baselines and automatically compares every PR against them, catching regressions in page load times, Core Web Vitals, and resource sizes before they reach production.
Use the benchmark skill to audit the performance of the current page and highlight any regressions against the saved baseline.

Catch web performance regressions by comparing current metrics against established baselines within your continuous integration workflow. This process validates every pull request for page load times, Core Web Vitals, and resource size changes before they reach production.
Baseline comparison works by recording initial performance metrics for critical pages, then automatically analyzing before and after metrics on subsequent updates. It triggers threshold-based alerts when timing, bundle size, or request count changes exceed defined regression limits.
You need the gstack browse daemon running to execute continuous integration performance benchmarks. This daemon executes JavaScript performance APIs and generates the comparative regression reports required to validate page load times and resource sizes.
Track gradual web performance degradation by monitoring performance trends over time using saved baselines. This identifies cumulative slowdowns caused by small changes, ensuring metrics like Largest Contentful Paint do not degrade unnoticed across updates.
You can set custom threshold alerts for JavaScript bundle size and LCP regressions. The comparison analysis triggers alerts when specific metrics exceed your configured percentage thresholds, such as blocking PRs that increase bundle size beyond 25%.
