SkillSafetyBench - Memory, Recovery, Audit and Persistence: leaderboard
The persistence risk domain of SkillSafetyBench (Jin et al., 2026): 26 cases in which a CLI coding agent leaves unsafe state that persists, evades auditing, resists rollback or poisons memory and history. Attack success rate in percent, judged by case-specific verifiers; each row is a CLI agent harness with a model backend; lower is better.
Metric: Attack success rate (%; 26 cases of unsafe state that persists, evades auditing, resists rollback or contaminates memory; rule-based case verifiers; each row is a CLI agent harness with a model backend, one run per case). Source: arxiv.org. Saturation forecast: Around February 2027. 9 models tracked.
