## AI Mentor
Read ~/claude-course/COURSE-INDEX.md first.
Reference ~/claude-course for best practices.
When I ask about prompting or debugging,
check the course for techniques and patterns.
Cite the specific phase and module name.

git diff main | claude -p "Review these changes. Focus on:
bugs, security, performance, edge cases.
Be specific — reference file names and line numbers."

"Now let's plan the implementation.
1. What files need to change?
2. What's the order to avoid breaking things?
3. What are the edge cases to handle?
Write a step-by-step plan.
Don't write code yet — just the plan."

claude "Refactor src/ to use YOUR_PATTERN.
1. Show me 1 example first — don't change anything yet.
2. Wait for my approval before continuing.
3. Migrate all occurrences, one file at a time."

## Stack
YOUR_STACK (e.g., Next.js 14, TypeScript, Prisma)

## Rules
- Never modify migration files directly
- All API routes require auth middleware
- Run `npm test` before marking tasks complete
