	Description		Read-only	Idempotent	Open world
`calculate_liability`Stateless insurance math: given an allowed amount and a plan snapshot (deductible, coinsurance, OOP max), returns exact patient responsibility, plan payment, and the breakdown, plus p25/p75 scenarios. Use when you already have a dollar amount (e.g. from an EOB or a prior estimate).

`check_financial_assistance`Screen a household for hospital financial assistance (charity care): returns income as a percent of the federal poverty guidelines, the typical range hospital policies cover, what federal rules (IRS 501(r)) do and do not guarantee, and next steps. Use when a user asks whether they might qualify for help paying a hospital bill. It is a screening estimate, not an eligibility decision: each hospital sets its own limits. Needs household size and annual household income; do not ask for names, account numbers or bill details.

`compare_bill_amount`Compares one dollar amount from a medical bill or explanation of benefits with the typical allowed-amount range (low, median, high) for the same procedure in the same US state, and says whether it is below, within or above that range, with questions worth asking the billing office. Pass amount_type 'billed' for the charge on the bill or 'allowed' for the insurer's allowed amount. Billed charges are usually higher than allowed amounts, so a high billed charge alone is not an error. Needs only the procedure, state and amount; do not send names, dates, account or member numbers.

`estimate_procedure_cost`Returns the typical allowed-amount range (low, median, high) for one medical procedure in one US state, the usual billing components (facility, physician, anesthesia, pathology), and the data vintage. If the user chooses to give their own deductible, coinsurance and out-of-pocket figures, it also returns an estimated patient share. These are estimates of typical prices from hospital price transparency and Medicare data, not quotes. Only the procedure and state are required; ZIP code and plan figures are optional and are used only for this one calculation.

`find_providers`Lists up to 5 facilities in one US state that perform a procedure, with name, address and a pricing_status field: 'observed' means a negotiated rate is published in that facility's price transparency data, 'estimated' means only a state-level benchmark applies, 'none' means no price data. Dollar amounts are not returned. The list is partial and is not a ranking or a recommendation.
