    Example session with this skill installed

    Plan a protected admin dashboard for an e-commerce site using Next.js 14, App Router, and Prisma. Needs to manage inventory and view sales analytics.

    • Read your context and instructions
    • Compiled the ultimate next js
    • Generated the UI component

    The plan outlines a server-first architecture for the admin dashboard, prioritizing secure Server Actions for inventory mutations and streaming for analytics.

    E-commerce Admin Dashboard Architecture

    ComponentResponsibilityStrategy
    layout.tsxAuth guard & SidebarServer Component: fetch session + nav
    inventory/page.tsxProduct listingServer Component: direct Prisma fetch
    inventory/actions.tsCRUD operationsServer Actions with Zod + Auth checks
    analytics/charts.tsxData visualizationClient Component: Recharts with passed data
    loading.tsxUX responsivenessInstant loading states for nested routes

    Implementation Plan

    // Example Server Action Structure
'use server'

import { z } from 'zod'
import { revalidatePath } from 'next/cache'
import { prisma } from '@/lib/prisma'
import { checkAuth } from '@/lib/auth'

const UpdateStockSchema = z.object({
  id: z.string().uuid(),
  quantity: z.number().min(0),
})

export async function updateStock(formData: FormData) {
  const session = await checkAuth('admin')
  if (!session) throw new Error('Unauthorized')

  const validated = UpdateStockSchema.safeParse({
    id: formData.get('id'),
    quantity: Number(formData.get('quantity')),
  })

  if (!validated.success) return { error: 'Invalid input' }

  await prisma.product.update({
    where: { id: validated.data.id },
    data: { stock: validated.data.quantity },
  })

  revalidatePath('/admin/inventory')
  return { success: true }
}

    Next steps

    1. Initialize the App Router structure with route groups (dashboard) to isolate admin layouts.
    2. Configure Middleware to handle server-side session redirects.
    3. Implement the Inventory Server Action with Zod validation as shown above.

    About this skill

    The problem

    Modern Next.js development often results in bloated client bundles, insecure Server Actions, and inefficient data waterfalls. Developers struggle to decide where to draw the boundary between Server and Client Components, leading to poor performance and security vulnerabilities.

    What it does

    • Architects full-stack Next.js applications using the App Router, ensuring correct Server/Client component boundaries.
    • Designs secure Server Actions with built-in input validation, authorization checks, and cache revalidation logic.
    • Audits existing codebases to identify unnecessary client-side JavaScript and data-fetching waterfalls.
    • Generates comprehensive implementation plans including route structures, metadata strategies, and testing coverage.
    • Optimizes data layers by defining caching strategies and revalidation requirements for specific data sources.

    Frameworks & tools

    Next.js 14+, React Server Components (RSC), TypeScript, Zod for validation, and NextAuth/Auth.js for session management.

    Why this beats prompting it yourself

    General-purpose LLMs often default to outdated Pages Router patterns or over-rely on Client Components. This skill enforces a server-first architecture, ensuring your app stays performant, secure, and aligned with modern Next.js best practices from the first line of code.

    Use cases

    • Architecting a high-performance dashboard with complex data fetching and nested layouts.
    • Refactoring a legacy Next.js app to utilize React Server Components and Server Actions.
    • Auditing an existing project for security risks in API routes and sensitive data leakage.
    • Planning a SEO-optimized public marketing site with dynamic metadata and streaming.
