Learn to classify agent failures in LLMs using post-hoc root cause analysis to improve reliability

advanced Published 29 Apr 2026
Action Steps
  1. Collect failure traces from LLM agent runs
  2. Apply root cause analysis to identify failure patterns
  3. Configure a classifier to predict failure causes
  4. Test the classifier on new failure traces
  5. Refine the classifier using feedback from users and agents
