Configures Lighthouse CI (`@lhci/cli`) to audit Web Vitals (LCP, INP, CLS) on every PR, asserts against canonical thresholds (LCP ≤2.5s, INP ≤200ms, CLS ≤0.1 at the 75th percentile), uploads Lighthouse reports as build artifacts, and posts deltas as PR comments. Includes a budget-authoring reference: per-route LCP/INP/CLS thresholds by traffic class (cached / dynamic / api-heavy / form-heavy / media-heavy) via `assertMatrix`, plus `budget.json` resource-size caps…
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
# lighthouse-perf ## Overview The **Core Web Vitals** are Google's three canonical user-experience metrics ([web-vitals][webvitals]): [webvitals]: https://web.dev/articles/vitals | Metric | Measures | "Good" threshold | |--------|-----------------------|--------------------------| | **LCP** (Largest Contentful Paint) | Loading performance | ≤ **2.5 seconds** | | **INP** (Interaction to Next Paint) | Interactivity | ≤ **200 milliseconds** | | **CLS** (Cumulative Layout Shift) | Visual stability | ≤ **0.1** | INP became a stable Core Web Vital in 2024, replacing FID ([web-vitals][webvitals]). The canonical measurement standard is **the 75th percentile** of page loads, segmented across mobile and desktop ([web-vitals][webvitals]). [lhci]: https://github.com/GoogleChrome/lighthouse-ci This skill covers **Lighthouse CI** (`@lhci/cli`) - the official Google Chrome team tool for running Lighthouse on every PR and asserting against budgets ([lhci][lhci]). ## When to use - The project ships a web frontend (Next.js, Vite, Remix, plain static, etc.). …

How to install
mdr add testland/qa/lighthouse-perf@sha256:7faaa0be988876d3The line at the top of this page pins the label git:20260813.bc28491, 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.
