# Material UI and Next.js

Agent skill for Next.js + Material UI wiring (SSR/streaming, cache providers, fonts, layers, Link, App Router URL state). SKILL.md is the entry; AGENTS.md is the full guide.

## When to apply

- New App Router or Pages Router app using `@mui/material`
- Styles missing, wrong order, or in `body` instead of `head`
- `next/font` + `ThemeProvider` / `createTheme`
- Tailwind or CSS Modules + MUI (`enableCssLayer`)
- `Button` + `component={Link}` or Next.js v16 client boundary errors
- `useSearchParams` / URL-driven MUI views and Suspense boundaries
