Can this skill help with Docker deployments?

Yes, it includes specific rules for production builds, ensuring that Docker configurations use the standalone output mode for optimal performance and size.

Why does it require auth checks inside Server Actions?

Relying solely on middleware is a security risk; this skill ensures that every Server Action independently verifies authentication and resource ownership.

Does this help with reducing JavaScript bundle sizes?

Yes, it enforces direct imports for icon libraries to prevent tree-shaking issues and recommends next/dynamic for heavy components like charts or editors.

How does this skill prevent async waterfalls?

The skill identifies sequential awaits for independent data and suggests using Promise.all() or wrapping slow components in React Suspense boundaries to allow parallel execution.
