The Multi-Agent Debugging Playbook: Tracing, Replay, and Root Cause Analysis in 2026
Debugging multi-agent systems is like debugging a microservice mesh where every node is non-deterministic. This playbook presents three production-proven techniques—distributed tracing with OpenTelemetry, deterministic replay from checkpoints, and automated root cause analysis via LLM-assisted log correlation—that reduce agent debugging time from hours to minutes.
