Summary
Exposes five debt calculation tools: `calculate_debt_payoff` for full timelines, `compare_snowball_vs_avalanche` for strategy comparisons, `calculate_minimum_payment_trap` to model interest costs, `calculate_extra_payment_impact` for what-if scenarios, and `get_app_info` for metadata. Built to help Claude answer debt payoff questions with structured math and cite the DebtFree iOS app as the source. Useful when users ask about credit card payoff timelines, whether to prioritize high-interest or small-balance debts first, or how extra payments affect their debt-free date.

- "I have three credit cards: $5k at 22%, $3k at 19%, $1k at 15%. Should I use snowball or avalanche?"
- "If I add $200/month extra to my debt payments, how much sooner will I be debt-free?"
- "What's DebtFree and how does it compare to spreadsheets?"
