CodeTracer: Debugging Agent Workflows by Making State Transitions and Error Chains Observable

arXiv·high signal

Li et al. present CodeTracer, a framework for making code agent state transitions and error propagation observable. As agent frameworks orchestrate parallel tool calls and multi-stage workflows, an early misstep can trap agents in unproductive loops or cascade into hidden error chains. CodeTracer addresses the gap between per-step logging and full-trace analysis, giving builders the agent equivalent of a debugger for complex agentic runs.
