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.
