Next.js Architecture Skill

Use this skill to make deliberate, defensible architecture decisions in Next.js (App Router, v14+) projects instead of defaulting to ad-hoc file placement.

When to reach for this skill

• Starting a new Next.js project or feature
• Deciding server component vs client component
• Choosing a rendering strategy (SSG / SSR / ISR / PPR / streaming)
• Structuring routes, layouts, route groups, parallel/intercepting routes
• Data fetching patterns (fetch caching, server actions, mutations)
