From Flat Logs to Execution Trees: Debugging Modern AI Agents

An agent trace is usually written as a sequence of events because append-only data is simple to produce: span_started span_started span_ended span_started span_ended span_ended Developers do not want…

  • Agent traces appear as a series of events due to append-only data structure simplicity.
  • Developers construct execution trees to visualize relationships between operations.
  • Reliable execution tree requires stable trace and span identity assignment.
