SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

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.

Core Features & Use Cases

  • Baseline creation and PR comparison for load times, web vitals, and resource sizes.
  • Trend analysis to identify gradual performance drift across builds.
  • Automated planning for performance alerts and reports during reviews.

Quick Start

Run the benchmark against a target URL to generate baselines and compare with the current build.

FAQPage Schema
How do I detect web performance regressions in a PR?▼

To detect web performance regressions in a PR, you need to benchmark Core Web Vitals and resource sizes against an established baseline. This Skill compares before and after metrics to flag performance drift during code reviews.

What metrics are included in a web performance baseline?▼

A web performance baseline includes Core Web Vitals and resource sizes. Specifically, it tracks metrics like TTFB, FCP, LCP, CLS, and overall page load times to establish a reference for future comparisons.

How do I track Core Web Vitals trends over time?▼

You track Core Web Vitals trends over time by running continuous benchmark comparisons across builds. This allows you to identify gradual performance drift and visualize metric changes through automated report generation.

Can I automate performance reports for pull request reviews?▼

Yes, you can automate performance reports for pull request reviews. The Skill applies automated planning to generate performance alerts and baseline comparisons directly within the review workflow.

Does this benchmark tool work with Lighthouse and web-vitals?▼

Yes, the benchmark tool works with Lighthouse and web-vitals. It uses the browse daemon and gstack tooling to analyze web performance metrics and generate trend reports for your target URLs.
