TRACE: Trajectory Risk-Aware Compression for Long-Horizon Agent Safety

In three linesTRACE, a trajectory compression method, detects safety risks in long-horizon LLM agents. A Compressor encodes the full trajectory into a supervised latent evidence state, while a Reader judges safety using this reference. Achieves up to 12.6 percentage point improvements on ASSEBench, Pre-Ex-Bench, and R-Judge.
