CausalFlow introduces an interventional framework for diagnosing and repairing failures in Large Language Model (LLM) agents. It systematically identifies causally responsible intermediate steps in failed execution traces and generates minimal, validated counterfactual corrections, achieving significant task accuracy improvements and providing precise supervision signals.

Key insights

  • Many LLM agent failures are localized to specific intermediate steps, making targeted, minimal interventions more effective than holistic regeneration.
  • Systematic causal attribution, validated through re-execution, can effectively diagnose the 'where and why' of failures, providing precise, localized feedback.
  • Minimality of repairs is crucial for maintaining agent behavior while correcting errors and for generating high-quality contrastive supervision for offline learning.
