Attributing Failures in Orchestrator-Workers Systems

Diagnose system issues (prompt failure, hallucinations, model mismatch)

SUBy Solomon UdohReviewed by Solomon UdohAI-assisted · human-reviewed
In short
Attributing failures in orchestrator-workers systems means tracing a coverage or synthesis failure back through the orchestrator and subagent boundaries to the true root cause. Failure boundaries between the orchestrator and its subagents can blur and traces can fragment. A dropped or failed subagent can fail silently at synthesis if there is no reconciliation against expected coverage. Diagnosis requires classifying whether a failure is recoverable at the subagent level (retry or flag) or unrecoverable and must propagate to the orchestrator, and a shared trace ID across all agents is required to reconstruct the failure path.
