Frontend Standards Into an Installable AI Skill — for React, Next.js, Vue, Angular, Svelte, Nuxt, Astro, and Plain HTML/CSS
Abayomi Olatunji released frontend-standard-skills on npm and GitHub. The tool provides one installable rule set per frontend stack that automatically enforces WCAG 2.1 AA accessibility and Core Web Vitals thresholds (LCP < 2.5s) in Claude Code and Cursor.
Why This Matters
Without automated standards enforcement, developers must manually prompt AI tools for accessibility or performance fixes on every file—a fragile workflow that produces inconsistent code. The package catalogues common failures like missing aria-labels or layout shifts from unspecified image dimensions into strict rules the AI reads autonomously during code reviews.
Key Insights
-
- Core Web Vitals thresholds: LCP < 2.5s , CLS < 0.1 , INP < 200ms measured against pagespeed.web.dev with Lighthouse CI pipeline enforcement (from context).
-
- Accessibility coverage: WCAG 2.1 AA requirements including full keyboard operability , semantic HTML over div-soup , correct ARIA usage , focus management , descriptive alt text , rem/em text scaling , prefers-reduced-motion patterns (from context).
-
- Installation methods: CLI (npx/npm/pnpm/yarn), Claude Code plugin marketplace (
/plugin marketplace add), manual folder copy to.claude/skills/, or global npm install (fss add nextjs) — writes to.claude/skills/<stack>/,.cursor/rules/<stack>-frontend-standards.mdc,CLAUDE.md, andAGENTS.mdwithout duplication on re-run (from context).

Working Examples
Practical Applications
-
- Use case – Teams using Claude Code or Cursor can run “Review ProductCard.tsx against our frontend standards” after installation; the AI consults rules on accessibility and Core Web Vitals automatically.
-
- Use case – Developers diagnose low PageSpeed scores by querying “Why is our PageSpeed score low on the homepage? Use our performance standards to diagnose it.”
-
- Pitfall – Re-prompting every time for accessible code leads to inconsistency; one component gets proper aria-label while another does not.
-
- Pitfall – Manually checking folder conventions per PR fails because the AI invents new ones unless rules are installed as a skill.
