SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill detects performance regressions in web pages by running baseline and comparison audits to surface changes that impact user experience.

Core Features & Use Cases

  • Full performance audits with TTFB, FCP, LCP, and other metrics using the browse daemon.
  • Baseline capture, comparison, and trend analysis across commits, branches, and deployments.
  • Page and resource breakdowns, bottleneck identification, and actionable recommendations.

Quick Start

Run the benchmark skill with a target URL to perform a full performance audit and baseline comparison.

FAQPage Schema
How do I detect web performance regressions across branches?▼

Web performance regressions are detected by running baseline and comparison audits. This Skill computes metrics like TTFB, FCP, and LCP to surface changes that impact user experience across commits and deployments.

How do I measure Core Web Vitals for a specific URL?▼

Core Web Vitals are measured by running a full performance audit against the target URL. The Skill extracts metrics such as TTFB, FCP, and LCP to provide a page and resource breakdown for bottleneck identification.

Do I need a browse daemon to capture web performance metrics?▼

Yes, a browse daemon is required to capture web performance metrics. The Skill depends on the browse daemon, baseline storage, and metrics extraction to perform page-by-page audits and trend analysis.

What's the best way to baseline web vitals for PR validation?▼

Baselining web vitals for PR validation involves capturing baseline metrics and comparing them against new changes. This Skill computes TTFB, FCP, LCP, and bundle sizes to validate pull requests and prevent regressions.

Can I track web performance trends over time across deployments?▼

Yes, you can track web performance trends over time across deployments. The Skill performs baseline capture and comparison to analyze performance trends, identifying bottlenecks and providing actionable recommendations.

What metrics are extracted during a web page performance audit?▼

Metrics extracted during a web page performance audit include TTFB, FCP, LCP, and bundle sizes. The Skill uses these metrics to perform baseline comparisons and identify bottlenecks impacting user experience.
