Planning & Setup Mistakes in AI

PITFALL: Starting Without A Plan
The mistake: Opening AI tool and starting with vague ideas
Why it fails: AI needs direction - inconsistent results, wasted time
The fix: Spend 30-60 minutes writing solid PLAN.md before code

PITFALL: Skipping Manual Setup
The mistake: Asking AI to "create a Next.js app with all the boilerplate"
Why it fails: You don't understand your foundation
The fix: Always run framework CLI yourself (create-next-app, rails new, etc)

PITFALL: Letting Context Get Stale
The mistake: Writing plan on day 1, never updating as things change
Why it fails: AI gives bad suggestions based on outdated information
The fix: Update PLAN.md and claude.md with architectural decisions
