Pros & Cons
What works
- Cheapest Pro tier ($15) with full agent capabilities vs Cursor ($20)

Watch out for
- Agent autonomy can produce unexpected results requiring review
- Credit system can be confusing for newcomers
- 25 free credits burn quickly (3-5 days of normal use)
- Less polished than Cursor for complex refactoring
