Report #77622

[architecture] Infinite recursive loops when agents delegate tasks back and forth

Enforce a maximum recursion depth or a strict Directed Acyclic Graph \(DAG\) topology for agent handoffs. Track the call stack in the orchestrator state; if an agent attempts to call an agent already in the active stack, abort and escalate.

Journey Context:
Autonomous agents with tool-calling capabilities can get stuck in 'ping-pong' loops \(e.g., Researcher asks Writer for format, Writer asks Researcher for content\). LLMs lack the global awareness to break these loops. A DAG prevents cycles entirely but limits dynamic delegation. Recursion depth limits allow dynamic delegation but require careful tuning to avoid cutting off legitimate deep searches.
