SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires gh, git, bash, and includes references (resource) and assets (resource) components.

What problem does it solve?

This Skill enables automated detection of performance regressions in web applications, helping developers identify slowdowns early.

Core Features & Use Cases

  • Performance Baseline Capture: Records page load metrics such as TTFB, FCP, LCP, and resource sizes for future comparison.
  • Regression Detection: Compares current performance metrics against stored baselines to identify regressions.
  • Trend Analysis: Shows historical performance trends over multiple benchmarks.
  • Use Case: Running a performance check before a release to ensure no new regressions have been introduced in critical pages, reducing user-impact issues.

Quick Start

Run the benchmark skill on a specific URL to measure page load performance and compare with previous baselines.

FAQPage Schema
How do I detect web page performance regressions automatically?

To detect web page performance regressions automatically, you can measure current page load metrics like TTFB, FCP, and LCP, and compare them against stored baselines to identify slowdowns before a release.

What web performance metrics should I monitor to prevent slowdowns?

You should monitor web performance metrics like TTFB, FCP, LCP, and resource sizes to prevent slowdowns, as capturing these baselines allows for accurate regression detection and trend analysis over time.

Can I integrate performance benchmarking into a CI/CD pipeline?

Yes, you can integrate performance benchmarking into a CI/CD pipeline for automated testing, allowing you to run checks on critical pages before releases and ensure no new regressions impact user experience.

How do I track historical web performance trends across multiple pages?

You can track historical web performance trends across multiple pages by running benchmarks that record metrics over time, enabling you to compare current results against previous baselines and visualize performance history.

Do I need bash and git to run web page load time benchmarks?

Yes, you need bash, git, and gh installed in your environment to run web page load time benchmarks, as the performance measurement and regression detection process relies on these command-line dependencies.

What is the best way to compare current web page load times against a baseline?

The best way to compare current web page load times against a baseline is to measure key metrics like FCP and LCP on a specific URL, then automatically check them versus stored baselines to pinpoint regressions.
