Sent verbatim as the prompt. The agent works in a copy of the workspace below and sees nothing else.

Match the payments in this morning's bank export to our open invoices. Give me unpaid.csv with the invoices still open (invoice_id, customer, amount_outstanding) and matches.csv showing what got applied where (invoice_id, line_id, amount_applied).
