DTap-Bench (Direct Attacks) - Customer Service: leaderboard

Direct misuse of tool-using agents in the customer service environments of DTap-Bench (Chen et al., 2026): the user is the attacker and pursues a harmful goal with optimized prompt, tool, skill and environment injections. Attack success rate in percent over 100 tasks, averaged over risk categories and judged by a rule-based check of the final environment state; lower is better.

Metric: Attack success rate (%; 100 direct red-teaming customer service tasks: the user is the attacker, with prompt, tool, skill and environment injections; an attack succeeds when a rule-based check of the final environment state finds the malicious goal fully achieved; fixed attack sequences that DTap-Red optimized on a surrogate agent; mean of its risk-category rates).
