Report #71959

[architecture] Infinite loops where agents hand off tasks back and forth without making progress

Enforce a strict Directed Acyclic Graph \(DAG\) for agent handoffs, or implement a hard maximum step/turn limit with a fallback to a human or generalist agent.

Journey Context:
Two specialist agents might continuously delegate to each other \(e.g., Agent A thinks Agent B should handle it, Agent B thinks Agent A should\). Cycles in agent routing cause infinite loops and runaway token costs. Forcing a DAG ensures forward progress, while a step limit acts as a circuit breaker for unresolvable ambiguity.
