Run and interpret Google Lighthouse audits for performance, accessibility, best practices, and SEO; compare reports, diagnose and verify improvements, audit authenticated user flows, and configure Lighthouse CI budgets and regression gates. Not for general browser debugging, Playwright test or harness work, backend load testing, custom audit/plugin development, or the Lighthouse ticketing service.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Google Lighthouse

Turn a page-quality question into reproducible measurements, actionable findings,
and verification appropriate to the claim. This is a portable workflow skill.
It uses upstream Lighthouse and Lighthouse CI (LHCI), without a bundled runner
or required host-specific interface. Reading an existing report needs no browser;
native execution needs a compatible Node runtime, Lighthouse, and Chrome/Chromium.
Scripted flows additionally need Puppeteer; CI collection needs LHCI.

## Choose the job and owner

| Requested job | Work and output | Change boundary |
|---|---|---|
| Interpret existing reports | Explain findings, compare compatible evidence, identify gaps | Read supplied artifacts; no new audit or source changes unless requested |
| Audit a URL or page state | Execute the relevant measurement and retain local reports | Browser activity and report files within the requested scope |
| Improve measured behavior | Inspect causes, implement requested fixes, rebuild and remeasure | Scoped source changes under existing authorization |
| Configure CI | Establish collection, assertions, and artifact handling | Requested tooling, configuration, and pipeline changes |

How to install

The exact contents, by fingerprint
mdr add n-n-code/n-n-code-skills/lighthouse@sha256:d2bde8c07c384a01

The line at the top of this page pins the label git:20260905.c5eb68d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
