Can I use Lighthouse Runner on local files?

Yes, the skill automatically starts a temporary local server to audit standalone HTML files directly from your local workspace.

Which metrics are included in the audit reports?

The report includes scores for Performance, SEO, Accessibility, and Best Practices, specifically highlighting Core Web Vitals like LCP, FID, and CLS.

Does this skill require a manual browser installation?

It uses Playwright to manage Chromium. While it attempts to install automatically, you can manually run the playwright install command if the browser is not found.

Can I export the audit data for other tools?

Yes, Lighthouse Runner supports a --json flag that outputs machine-readable data, perfect for integrating with custom dashboards or CI/CD pipelines.

Does it work with frameworks like Next.js or Remix?

Absolutely. You can run the audit against your local development server (e.g., localhost:3000) while your application is running.
