Cowork-style sweep of a folder of receipts, statements, and expense exports -- categorizes every transaction, matches receipts to statement lines, flags policy violations and anomalies, and outputs a clean expense report plus a findings memo.
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 Expense Audit Process an expense folder the way a careful controller does: reconcile receipts against statements, categorize consistently, and separate what is provably documented from what is missing. Input is a directory of receipts (PDF, images), card/bank statements, and any expense exports (.csv/.xlsx). Never invent an amount -- every number in the output traces to a source file. ## Workflow 1. **Inventory.** Catalog every file: receipts, statements, exports, and unclassifiable items. Note date ranges covered. If statements and receipts cover different periods, say so up front. 2. **Extract transactions.** Build a master ledger from the statements/exports: date, merchant, amount, currency. From each receipt: merchant, date, total, tax, payment method, line items when legible. 3. **Reconcile.** Match receipts to statement lines (exact amount+date first, then fuzzy within 3 days and small tip/FX variance). Output three lists: matched, statement lines with no receipt, receipts with no statement line. …

How to install
mdr add onewave-ai/claude-skills/cowork-expense-audit@sha256:5116cda141419fc3The 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.
