Learn to debug multi-agent LLM traces without replaying the entire execution, reducing debugging time and cost

advanced Published 16 Jun 2026
Action Steps
  1. Apply knowledge-based debugging to identify potential causally decisive events in LLM traces
  2. Use counterfactual analysis to evaluate the impact of each event without replaying the entire execution
  3. Configure a debugging framework to integrate knowledge-based debugging with counterfactual analysis
  4. Test the framework on a sample multi-agent LLM system to evaluate its effectiveness
  5. Compare the results of knowledge-based debugging with traditional counterfactual replay to measure the reduction in debugging time and cost

Title: Knowledge-Based Zero-Replay Debugging of Multi-Agent LLM Traces

Abstract:
arXiv:2606.14805v1 Announce Type: cross Abstract: Reliable operation of multi-agent large language model (LLM) systems depends on debugging long execution traces, where the few causally decisive events are buried in unstructured logs of messages, routes, memory writes, and tool calls. The standard tool is counterfactual replay (rewind, edit, and re-run the trajectory to measure each event's effect), but its cost grows linearly with the number of candidate events, making exhaustive replay infeasi
