    Description, as the server wrote it
    Project the cumulative cost of a fee list over 1-30 years by straight multiplication of each recurring fee's annualized amount, with one-time fees counted once (no compounding or inflation), with a per-fee breakdown. Use for 'what will these cost me over N years'. It does not flag fees: use audit_fees to find problem charges, benchmark_fees for typical ranges.

    Description, as the server wrote it
    Audit a list of fees: annualize each one (monthly x12), total the yearly cost and monthly average, and flag charges above the typical US range for their category, duplicate names and one-time fees of $30+ worth disputing. Use when the user lists fees to review. For a multi-year projection use annual_cost; for typical ranges alone use benchmark_fees.

    Description, as the server wrote it
    Look up typical US consumer fee ranges (min/max per charge, USD) for one category such as bank_overdraft, or the full 14-category table when category is omitted. Use to answer 'is this fee normal?' questions. To check a user's own list of fees against these ranges, use audit_fees.

    Description, as the server wrote it
    Draft (text only; nothing is sent) a firm, polite letter asking a company to reverse or refund one specific fee, with grounds, a 14-day written-response request, an escalation path and sending tips. Use once the user has picked a fee to contest. To find which fees are worth disputing first, use audit_fees.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
