About this skill
The Next.js 15 & React 19 Production Architect skill upgrades your AI coding assistant (Claude Code, Cursor, Windsurf, Antigravity) into a Principal Software Architect. It enforces modern Next.js 15 standards—such as async params handling, uncached fetch defaults, and tag-based revalidation—while ensuring your application stays ultra-fast and type-safe.
This skill guarantees that all generated Server Actions pass strict security gates with authentication checks and Zod input validation. It prevents SSR hydration mismatches, optimizes client/server component boundaries, and outputs actionable architectural audit reports to keep your codebase enterprise-ready.
