Next.js Best Practices

Apply these rules when writing or reviewing Next.js code.

Cache Components patterns: When the project has cacheComponents: true in next.config.ts, use the separate cache-components skill for 'use cache', cacheLife(), cacheTag(), updateTag(), and revalidateTag() guidance.

File Conventions

See file-conventions.md for:

• Project structure and special files
• Route segments (dynamic, catch-all, groups)
• Parallel and intercepting routes
• Middleware rename in v16 (middleware → proxy)

RSC Boundaries

Detect invalid React Server Component patterns.
