Report #54562

[architecture] Multi-agent orchestrations deadlock when agents are granted mutually exclusive tool capabilities that depend on each other

Model agent capabilities as a Directed Acyclic Graph \(DAG\) where tool access flows strictly downstream, preventing circular dependencies between agents.

Journey Context:
If Agent A can call Tool X \(which needs output from Tool Y\) and Agent B can call Tool Y \(which needs output from Tool X\), they can deadlock waiting for each other. Unlike database transactions, LLM agents cannot easily rollback and retry deadlocks. The architectural fix is to strictly partition tools by agent role in a DAG, ensuring no circular dependencies exist in the capability graph.
