Report #4105

[architecture] Multi-agent workflows deadlocking because Agent A waits for Agent B's output while Agent B waits for Agent A

Model agent dependencies as a Directed Acyclic Graph \(DAG\) and validate the graph has no cycles before execution. Use event-driven triggers rather than synchronous blocking waits between agents.

Journey Context:
Synchronous RPC-style calls between agents create tight coupling. If Agent A calls Agent B and blocks, and B calls A, the system deadlocks. By modeling dependencies as a DAG, you guarantee forward progress and allow the orchestrator to schedule independent tasks in parallel. The tradeoff is that DAGs require upfront definition of the workflow, reducing dynamic flexibility, but preventing deadlocks is a non-negotiable prerequisite for reliable execution.
