create-new-project

When to use

Use this skill whenever the user wants to start a new web app using the standard stack:

• Next.js (App Router) + TypeScript
• Tailwind CSS + shadcn/ui
• Supabase (Postgres, Auth, Storage, Realtime)
• Deploy on Vercel
• API routes in Next.js for internal + third-party integrations

What you must ask (minimal)

Ask only what is necessary:

1. Project name (kebab-case recommended)
2. Package manager: pnpm (default) / npm
3. Supabase mode:
   • "local-first" (init Supabase locally + migrations)
   • "cloud-only" (create env placeholders; user will link later)

If the user explicitly wants external integrations, confirm:

• "public API for third-party order creation" yes/no (default: yes)

Execution plan (do this in order)

1. Create the project folder using the script (pick the right OS reminder):

   • macOS/Linux/Git-Bash/WSL: bash scripts/create-new-project.sh <name>
   • Windows PowerShell: powershell -ExecutionPolicy Bypass -File scripts/create-new-project.ps1 -Name <name>

2. Ensure the scaffold includes:

   • Next.js app (App Router) + Tailwind
   • shadcn/ui initialized
   • Supabase client helpers (server + browser)
   • .env.example + .env.local placeholders (never commit secrets)
   • Supabase migration file with baseline schema for orders/sales (multi-tenant ready)
   • Example API routes:
     • /api/v1/orders (authenticated internal)
     • /api/v1/public/orders (API key for third-party callers)

3. After generation, run:

   • install deps (if not already)
   • pnpm dev (or npm) quick smoke test
   • if Supabase CLI present and local-first: supabase init and confirm migration file exists

4. Output to the user:

   • what was created (high-level)
   • exact next steps to connect Supabase Cloud + Vercel env vars
   • how to call the public API endpoint from another system

Guardrails

• Do NOT add next-themes/react-day-picker unless versions are compatible with the chosen React/Next baseline.
• Do NOT commit .env.local, Supabase service role keys, or Vercel tokens.
• Keep the project "boring": simple, predictable, production-ready defaults.
