SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The skill enables teams to measure, baseline, and compare web performance to identify regressions across builds and PRs.

Core Features & Use Cases

  • Baseline capture and storage for performance metrics.
  • Full-page performance audits (TTFB, FCP, LCP, etc.) and resource analysis.
  • Comparison reports and trend analysis across branches and PRs.
  • Generate Markdown and JSON artifacts for sharing and automation.

Quick Start

Run a full benchmark on a target URL to capture metrics, compare against the latest baseline, and generate a report.

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

How to track web performance regressions? Track web performance regressions by running full audits on URLs, capturing key metrics like TTFB and LCP, and comparing current results against stored JSON baselines. This workflow generates markdown reports for historical trend analysis.

What metrics are included in a web performance baseline comparison?

A web performance baseline comparison includes key web-vitals metrics such as TTFB, FCP, and LCP. The audit collects these metrics during a full-page performance run and stores them in a JSON baseline for deterministic historical trend analysis.

Can I automate performance benchmarking for production-like environments?

Yes, you can automate performance benchmarking for production-like environments. The skill applies to URLs in PR workflows and production-like setups, running full audits to capture baselines and producing deterministic JSON artifacts for automated trend analysis.

Does web-vitals trend analysis work across different git branches?

Does web-vitals trend analysis work across branches? Web-vitals trend analysis works across branches by capturing baseline metrics from full-page audits and comparing current runs against them. It generates markdown reports with per-page metrics to visualize performance trends over time.

What format are the performance benchmark reports generated in?

Performance benchmark reports are generated in both Markdown and JSON formats. The JSON format enables deterministic baseline storage and automated comparisons, while the Markdown format provides shareable per-page metric summaries and trend analysis reports.
