Shortcut Sensitivity in Agent-Safety Evaluations

AI agents take actions through tools.

Key points

  • We introduce a three-level shortcut-auditing framework and audit completed LinuxArena trajectories and two TS-Bench-derived step datasets.
  • We distinguish label predictability, observational guard association, and paired decision sensitivity.
  • In AgentHarm-Traj, released TS-Guard F1 falls from .902 under row weighting to .719 with equal interaction weighting, while balanced accuracy rises.
  • We then test the strongest safe-row marker association in a seven-configuration screen on a frozen 64-step AgentDojo-Traj cohort using repeated, interleaved Haiku calls.
