CommerceAgentBench Grades Agents on Operational Traces, Not Self-Reports — and Hides BEC Fraud in the Inbox

alifcoder · x · 2026-08-26

CommerceAgentBench grades agents in an unusual way: not by what the model says it did, but by checking operational traces left in the environment — whether the label was applied, the draft saved, the calendar event created, plus listings, bookings, shipment IDs, and cross-system data. It also embeds a security layer with BEC payment-redirection risk hidden among legitimate procurement emails; the agent must flag suspicious payment changes without over-flagging, then still act: select suppliers, apply labels, save drafts, and create events.
