SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Page performance regressions slip into code changes and PRs, leading to slower experiences for users. This skill provides a repeatable, automated way to baseline, measure, and detect regressions across pages and builds.

Core Features & Use Cases

  • Baseline capture and diff reporting
  • Page timing metrics: TTFB, FCP, LCP, DOM interactive, DOM complete, and full load
  • Resource and bundle size analysis with top offenders
  • Trend analysis across historical benchmarks and multi-page sets

Quick Start

Run /benchmark <url> to perform a full performance audit against the current baseline.

FAQPage Schema
How do I detect web performance regressions in my pull requests?

To detect web performance regressions in pull requests, you can run a browser-based benchmark that collects navigation timing, resource timing, and bundle-size data to compare against a baseline.

What page timing metrics are captured during a web performance benchmark?

A web performance benchmark captures TTFB, FCP, LCP, DOM interactive, DOM complete, and full load times. It also collects resource timing and bundle-size data to identify top offenders.

How do I establish a performance baseline for my web application?

To establish a performance baseline for your web application, run a benchmark against your target URL. This records the initial navigation timing, resource timing, and bundle-size data.

Can I analyze bundle size and identify top offenders impacting web performance?

Yes, you can analyze bundle size and identify top offenders impacting web performance. The benchmark collects resource timing and bundle-size data, highlighting specific assets causing regressions.

What is the best way to track web performance trends across multiple builds?

The best way to track web performance trends across multiple builds is to use a benchmark tool with trend analysis mode. It compares historical benchmark data across multi-page sets to visualize shifts.

Does benchmarking web performance require any external dependencies or components?

Benchmarking web performance with this skill requires no external dependencies or components. It operates standalone to run browser-based benchmarks and report structured timing results.
