Point Cowork at a folder of medical bills and insurance EOBs -- matches every bill to its explanation of benefits, catches duplicate charges, balance-billing, and bills that ignore your insurance, then drafts the dispute letters and phone scripts. Most medical bills contain errors; this finds them.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cowork Medical Bill Auditor Audit medical bills the way a patient advocate does: never pay a bill that has not been matched to its EOB, know exactly what the insurer said the patient owes, and dispute in writing. Input: a folder of provider bills, insurance EOBs (explanation of benefits), and any payment records. This is billing-accuracy support, not medical or legal advice. ## Workflow 1. **Inventory and pair.** Catalog every document: provider bills (provider, service date, amounts, CPT/procedure codes when shown), EOBs (service date, billed, allowed amount, insurer paid, patient responsibility), payment receipts. Match each bill to its EOB by provider + service date + amounts. 2. **Audit each pair.** Check: bill's patient-owed amount vs. the EOB's patient-responsibility line (they must match); charges the EOB shows as insurer-paid or write-off still appearing on the bill; duplicate line items across bills for one visit; charges for services on dates with no corresponding visit; in-network providers billing above the allowed amount (balance billing, prohibited in most network contracts and, for many scenarios, under the No Surprises Act). …

How to install
mdr add onewave-ai/claude-skills/cowork-medical-bill-auditor@sha256:d985913b90299f23The line at the top of this page pins the label git:20260715.bc89719, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
