Report #87158

[architecture] Infinite handoff loops between agents when tasks fail or responsibilities overlap

Enforce a maximum depth limit on agent handoffs and append a monotonically increasing hop\_count or call\_depth to the inter-agent message payload.

Journey Context:
When agents are given the ability to delegate or transfer tasks, they can get stuck in infinite loops if Agent A thinks Agent B should handle it, and Agent B thinks Agent A should handle it. By tracking the depth of the call stack and terminating with an error or escalation when it exceeds a threshold, you prevent runaway token consumption. Tradeoff: arbitrarily cutting off deep chains might abort valid complex reasoning, but the cost of infinite loops usually outweighs this risk.
