Performance regression detection using the browse daemon. Establishes baselines for page load times, Core Web Vitals, and resource sizes. Compares before/after on every PR. Tracks performance trends over time.
Run the benchmark against a target URL to measure and compare performance and save results to .gstack/benchmark-reports.

To detect web performance regressions on a pull request, this Skill collects baseline page load metrics and resource sizes, then compares current runs against stored baselines to alert on degradations before merging changes.
Tracking Core Web Vitals trends over time involves establishing baselines for metrics like TTFB, FCP, and LCP, then analyzing historical run data stored in benchmark reports to identify long-term performance degradation.
Yes, you can measure page load times and resource sizes without external dependencies by using the built-in browse daemon to gather data, storing results directly under the local .gstack/benchmark-reports directory.
Baseline creation for web vitals and DOM metrics works by running the benchmark against a target URL to measure current performance, saving those initial TTFB, FCP, LCP, and resource size values as a comparison anchor for future runs.
You need to monitor performance across commits to catch regressions early during PR validation, ensuring that recent code changes do not degrade established page load baselines or increase resource sizes over time.
