SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables teams to proactively detect performance regressions by establishing baselines for page load times, Core Web Vitals, and resource sizes, and comparing new runs against historical data on every PR.

Core Features & Use Cases

Baseline and compare PR performance using the browse daemon's perf tooling.
Track performance trends over time and surface regressions early.
Support multi-page audits and targeted page sets with --pages, --diff, or --trend.

Quick Start

Run the benchmark on a target URL to start data collection, baseline setup, and comparison.

FAQPage Schema

How do I detect web performance regressions on a pull request?▼

You can detect web performance regressions on a PR by baselining page load times, Core Web Vitals, and resource sizes, then comparing new runs against historical data. This Skill automates that collection and diffing process using the browse daemon.

Can I track Core Web Vitals across multiple pages for long-term trend analysis?▼

Yes, you can track Core Web Vitals trends over time by running multi-page audits. It supports a trend mode to measure targeted page sets and surface long-term performance changes across your historical data.

What do I need to set up before collecting page load metrics?▼

You need the browse daemon and perf tooling set up in your environment to collect page load metrics. Once running, the tool measures load times, Core Web Vitals, and resource sizes to establish your baseline.

What is the best way to compare current page performance against a historical baseline?▼

The best way to compare current performance against a baseline is using the diff mode. It automatically measures new page load metrics and resource sizes, then compares them against your previously established historical data.

Does this benchmark tool support evaluating custom JavaScript during a page audit?▼

Yes, the benchmark tool supports optional JavaScript evaluation during multi-page audits. This allows you to collect custom metrics alongside standard Core Web Vitals and page load times.

When should I use the quick mode versus the full pages mode for performance testing?▼

Use quick mode for immediate, lightweight performance checks on a target URL, and use pages mode for comprehensive multi-page audits. Both modes collect Core Web Vitals and resource sizes for regression detection.
