SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Web performance regressions slip through PRs, harming user experience and release credibility. This Skill provides automated baselining and regression detection to surface slowdowns before users notice.

Core Features & Use Cases

Baseline creation and regression detection using a browse daemon.
Per-page metrics collection (TTFB, FCP, LCP, DOM times) with reports suitable for PR reviews.
Use Case: Teams can run benchmarks on new builds to verify performance budgets are met.

Quick Start

Run the benchmark against a URL to start a baseline-driven performance audit.

FAQPage Schema

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

Web performance regression detection compares current browse daemon metrics against a stored JSON baseline to identify slowdowns in TTFB, FCP, and LCP before merging.

What web performance metrics do I need to collect for baseline testing?▼

Baseline web performance testing requires collecting TTFB, FCP, LCP, DOM times, and resource usage metrics per page using a browse daemon to generate comparable JSON results.

How do I create a performance baseline for my web application?▼

Creating a performance baseline involves running a benchmark against a URL with a browse daemon to capture initial metrics, then storing these JSON results for future regression comparisons.

Can I run browser performance benchmarks locally without external dependencies?▼

You can run browser performance benchmarks locally by using a browse daemon and storing baseline JSON results on your system, requiring no external dependencies to measure page metrics.

What is the best way to automate performance budget checks in CI workflows?▼

Automating performance budget checks in CI workflows involves comparing new build browse daemon results against a stored local baseline to verify metrics like LCP and TTFB meet PR review standards.
