Report #87358

[architecture] Infinite handoff loops between agents bouncing fixes back and forth indefinitely

Enforce a hard maximum iteration limit \(max\_rounds or max\_depth\) at the orchestrator level. When the limit is hit, break the loop, dump the state, and route to a human or a fallback summarizer agent.

Journey Context:
LLMs lack global awareness of how many times they have interacted. If a bug is unfixable, Agent Coder and Agent Tester will hand off to each other endlessly, burning tokens and budget. You cannot rely on the LLMs to realize they are stuck. A deterministic circuit breaker in the orchestrator is mandatory. The tradeoff is that you might cut off a legitimate complex fix that requires many iterations, so the limit must be tuned to the specific workflow's expected complexity.
