Researchers from Peking University and NUS show that exposing benchmark success criteria to self-improving embodied coding agents inflates measured success on those criteria without improving instructed-task completion. The advantage fades under slight criteria changes and transfers poorly across tasks; instruction-faithful criteria better reflect real performance.
