SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Web performance regressions slip into PRs and slow user experience; this skill establishes baselines for page load times, Core Web Vitals, and resource sizes, enabling rapid detection of regressions.

Core Features & Use Cases

Baseline creation for page load times, Core Web Vitals, and resource sizes.
Automated before/after comparisons on PRs with trend history over time.
Page-level performance analysis across a configurable set of pages, with detailed metrics and reports.

Quick Start

Run /benchmark <url> to generate a full performance report and baseline comparison.

FAQPage Schema

How do I benchmark web performance and detect regressions in a PR workflow?▼

To benchmark web performance in PR workflows, measure page load times, Core Web Vitals, and bundle sizes before and after changes to detect regressions. This Skill automates scripted data collection, baseline storage, and delta reporting for quick decision making.

What is the best way to track Core Web Vitals like TTFB, FCP, and LCP over time?▼

Tracking Core Web Vitals like TTFB, FCP, and LCP requires establishing performance baselines and comparing trends over time. This Skill implements automated before/after comparisons and trend history to monitor regressions across configurable web pages.

Can I compare before and after performance metrics for specific web pages?▼

Yes, you can compare before and after performance metrics for specific web pages using automated delta reporting. By running benchmark commands against target URLs, the Skill generates detailed performance reports and baseline comparisons for page-level analysis.

How do I establish a performance baseline for web page load times and resource sizes?▼

Establishing a performance baseline for page load times and resource sizes involves running a benchmark command against target URLs. The Skill then stores these baselines to enable rapid detection of regressions in future PR comparisons.

Does this benchmarking approach work without external dependencies or components?▼

Yes, this benchmarking approach works without external dependencies or components. It uses the integrated browse daemon for data collection and requires no additional modules to measure baselines, compare results, and track performance trends.

Why do web performance regressions slip into pull requests undetected?▼

Web performance regressions slip into pull requests when there are no established baselines for Core Web Vitals and bundle sizes. Without automated before/after comparisons and trend tracking, slow user experience issues go unnoticed until they reach production.
