Report #26561

[architecture] Multi-agent systems enter infinite handoff loops \(Agent A calls B, B calls A\)

Enforce a maximum depth/turn limit on agent handoffs at the orchestrator level, and include the calling agent's identity in the handoff context so agents can avoid delegating back to the immediate caller.

Journey Context:
LLMs don't naturally track recursion depth. If two agents have overlapping capabilities, they can easily bounce a task back and forth. The orchestrator must act as a circuit breaker. Tracking the call stack \(who called whom\) and hard-limiting the total number of handoffs prevents runaway API costs and infinite loops.
