SkillAtlas releases 3,014 agent skill attack cases and 6,589 trajectories; authors self-report 42.5% of successful attacks succeeded only after a failed first attempt.

You can now search 3,014 agent skill attack cases, 6,589 trajectories, 233 affected skills and 8 risk categories, drawn from the vetted, desensitised public attack trajectory library SkillAtlas.
Previously, agent skill security reports were mostly private, and existing static, dynamic and benchmark-style evaluations rarely preserved publicly verifiable evidence.
The authors self-report that 42.5% of successful attacks succeeded only after a failed first attempt, and that trajectory-based labels raise pre-execution defence accuracy to 0.770; all these figures are self-reported by the authors.
The preprint was submitted to arXiv on 11 September by Yuxin Tian, Liang Pang and three other authors (arXiv:2609.13353), has been accepted to the EMNLP 2026 REALM workshop as a non-archival paper, and has not yet been reproduced by others.
