TRACE attributes 72.7% of agent failures

TRACE reports 72.7% root-cause attribution and 82% end-to-end fix effectiveness on 60 agent dissatisfaction traces spanning three complexity tiers. The arXiv paper mines corrections, rephrasing, and abandonment cues from historical trajectories, then uses exploratory verification to distinguish missing context that needs CREATE from stale context that needs UPDATE, reaching 96% operation accuracy. Teams maintaining prompts, skills, tool descriptions, or knowledge bases should treat interaction logs as a context-debugging dataset and validate automated edits on their own failures, extending the case for a governed agent control plane.
