SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The performance benchmark skill helps teams detect slow changes by running browser-based performance tests and comparing results against historical baselines, enabling proactive performance management.

Core Features & Use Cases

  • Establish baselines for page load metrics (TTFB, FCP, LCP, DOM timings) and resource sizes.
  • Compare current results against baselines on PRs, support diff and trend analyses, and generate actionable insights.
  • Use across multi-page scenarios and CI workflows to identify regressions early and guide optimization decisions.

Quick Start

Run /benchmark <url> to start a performance audit and automatically compare it to the stored baseline.

Frequently Asked Questions about benchmark

High-intent search queries and answers about installing and using this skill.

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

Establish a performance baseline by running browser-based benchmarks on target URLs to record initial TTFB, FCP, LCP, DOM timings, resource sizes, and bundle sizes under `.gstack/benchmark-reports` for future comparison.

How do I analyze performance trends across multiple pages?▼

Analyze performance trends by running the benchmark across multi-page scenarios using `--trend` and `--pages` modes, comparing historical baseline data to generate actionable insights on metric degradation over time.

What web vitals and load metrics are captured during a performance benchmark?▼

Compare current benchmark results against the stored baseline using `--diff` mode to highlight metric deviations across multiple pages, generating actionable insights to identify performance regressions.

Can I run a quick performance audit without executing the full benchmark suite?▼

Run a quick performance audit by passing the `--quick` flag to execute a faster benchmark pass, still capturing core web vitals while reducing execution time for rapid checks.
