# Frontend Lighthouse (portable performance gate) > Portable skill — readable by Claude Code, OpenCode, Codex, Cursor, Windsurf, and others. > This skill describes a **CI performance gate** — a Lighthouse CI config plus a workflow — not a > component library or a visual style. It pairs with the **frontend-seo** and > **frontend-architecture** skills: SEO writes the metadata, Lighthouse proves it ships fast. The goal: every pull request is **blocked unless the production build meets explicit Core Web Vitals budgets and category score floors**. Budgets live in **one** `lighthouserc.cjs`, runs are **median-of-N** so the gate doesn't flake, and the same config runs locally and in CI. ## When to Use This Skill - Use when adding a Lighthouse CI performance gate to a web app. - Use when setting Core Web Vitals budgets for LCP, CLS, and TBT as the lab proxy for INP. - Use when configuring category score floors for performance, SEO, accessibility, and best practices. - Use when debugging flaky Lighthouse runs or making reports visible as CI artifacts. --- ## 0.

What does the frontend-lighthouse skill do?
Add a portable Lighthouse CI gate for production frontend builds with Core Web Vitals budgets, category floors, median runs, and CI artifacts.
How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill frontend-lighthouse --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
