This skill detects performance regressions by measuring key web metrics such as TTFB, FCP, LCP, and resource load across pages, and compares them against baselines to surface regressions early.
Run /benchmark <url> to begin a full performance audit and baseline comparison.

Detect web performance regressions by capturing a baseline for Core Web Vitals like TTFB, FCP, and LCP, then comparing new measurements against it. This skill automates that diff across PRs to surface regressions early with structured JSON and Markdown reports.
Measure Core Web Vitals for a multi-page web app by running a performance audit against the target URL. This skill uses the browse daemon and in-page performance APIs to collect resource timing and bundle analysis data for each page.
Yes, benchmarking web vitals and bundle size requires a local setup with a bun or Node toolchain and the gstack environment. You also need network access to the target URL you intend to audit.
The best way to visualize performance trends over time is by capturing baseline metrics and running diffs across multiple branches. This skill generates per-page trend analysis reports to highlight changes in resource load and bundle metrics.
Yes, you can generate performance reports for stakeholders automatically. After measuring page metrics and comparing baselines, the skill outputs structured JSON and Markdown reports containing actionable recommendations.
