AI needs constraints to be useful.

Without structure, every project becomes a different architecture. That's AI slop.

WITHOUT STARTUPKIT
?Where should auth logic live?
?Prisma or Drizzle? Which pattern?
?App router or pages? RSC or client?
?How do I structure shared code?
?Which analytics provider? How to abstract?

Burn tokens reinventing the wheel. Every project starts from zero.

WITH STARTUPKIT
@repo/auth → Better Auth, ready
@repo/db → Drizzle + Postgres, configured
@repo/ui → 60+ Shadcn components
Monorepo structure → share everything
AGENTS.md → AI knows the architecture

Start at 70%. AI handles the details, not the foundation.
