Does this skill support Next.js 15 and 16?

Yes, it includes specific patterns and updates for Next.js 15 (React 19, uncached fetch) and Next.js 16 (middleware transitions to proxy.ts and Cache Components).

What is the 7-step Server Action security protocol?

It is a rigorous security pattern included in this skill that covers rate limiting, auth verification, Zod validation, authorization checks, safe mutations, granular revalidation, and audit logging.

How does this skill handle state management?

It enforces a state hierarchy that prioritizes URL state for shareable data, Server Components for data fetching, and specialized hooks for form and UI state.

Can I use this for existing projects or only new ones?

You can use it for both. The /next-audit command is specifically designed to analyze existing codebases for anti-patterns, security risks, and performance bottlenecks.
