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

Hannah needs our Q2 sales tax figures for the return, by jurisdiction, on the upload template. The POS export, the state's rate table, our exemption certificates and her email are in the folder. Save it as tax_liability.csv.
