Report #11113

[architecture] Multi-agent systems deadlock when agents wait on each other for shared resources or sequential tool outputs

Design agents with non-blocking, asynchronous tool calls and implement timeouts with default fallback actions; avoid circular dependencies in agent handoffs by enforcing a Directed Acyclic Graph \(DAG\) of agent interactions.

Journey Context:
If Agent A calls a tool that requires a state set by Agent B, and Agent B requires a state set by Agent A, the system halts silently or loops infinitely. LLMs do not inherently understand distributed systems deadlocks. You must map the dependency graph of agent capabilities beforehand. If A needs Bs output, B must not need As. Enforcing a DAG topology prevents circular waits.
