Continuing experiments with Typesafe's Jev, the author demos software telling another software "don't buy this" with confidence scores: a store's catalog API convinced a shopping agent to abandon a $149 trail shoe purchase, returning returnrisk 2/2 (100% confident) and honestdisclosure 1.95/2 (92%). The evaluation factored in buyer foot data, return history of two prior pairs, and reviews noting narrow toe boxes—entirely without human involvement.
