About cost
Each question you ask costs roughly $0.05–$0.10 in Anthropic API credits, because the tutor sends the reference notes (worked errors, pattern cheat sheet, practice problems) with every message. A typical question takes 3 round trips (Check 1 → Check 1.5 → Solve), so budget ~$0.20 per complete solve. You can see your actual usage at console.anthropic.com.
