Report #80023

[architecture] Agents enter infinite handoff loops where Agent A transfers to Agent B, who immediately transfers back to Agent A

Inject a monotonically increasing handoff counter into the shared orchestration state, and hard-fail the execution loop when it exceeds a strict threshold \(e.g., 5 handoffs\).

Journey Context:
When agents lack the context to resolve a task, they often default to 'not my job' and hand off. Without a circuit breaker, this ping-pongs forever, burning tokens. Adding a counter is a simple, deterministic guardrail. Some try to use LLM reasoning to prevent loops, but LLMs are unreliable at counting prior steps. A programmatic check is required. The tradeoff is that complex workflows might hit the limit prematurely, requiring tuning, but it prevents catastrophic infinite loops.
