This skill prevents performance degradation by automating the detection of regressions in page load times, Core Web Vitals, and resource sizes before they reach production.
Run the benchmark skill on the homepage to capture a new performance baseline.

To detect performance regressions in a pull request, you can automate measuring page load times, Core Web Vitals, and resource sizes against historical baselines before code changes merge.
Core Web Vitals are metrics like Largest Contentful Paint used in benchmarking to establish baselines and identify if recent code changes increased load times or bundle sizes.
You establish a performance baseline for web application pages by running the benchmark skill on your homepage to capture initial page load times, Core Web Vitals, and resource sizes for future comparison.
Yes, you need browser-based performance APIs and the browse daemon to access, collect, and analyze web vitals and resource size metrics required for continuous performance monitoring.
Yes, you can measure Largest Contentful Paint changes for every code update by integrating regression detection into your workflow to compare current metrics against historical baselines.
Performance benchmarking fails without the browse daemon because it requires browser-based performance API access to collect and analyze page load times, Core Web Vitals, and resource sizes.
