danielrupawalla reports finding defects in 65% of TAU-banking tasks, where policies aren't enforced correctly: models can take out-of-scope actions unpunished (tool-call checks only, no DB verification), lie to customers with no penalty (no communication checks), and naive tool-call checks impose no consequences on failures. Shared by Hamel Husain. Recommendation: harden grading before using such benchmarks.
