[architecture] Agents hand off to each other in an infinite loop

Enforce a maximum handoff depth and implement a terminating agent pattern where the last agent must execute a tool rather than hand off.

Journey Context:
LLMs often exhibit buck-passing behavior, handing a task back to the router or another agent when unsure. This creates a ping-pong loop. Tradeoff: Hard limits on handoffs might truncate complex but valid workflows. Mitigation: Track handoff count in shared state; if limit reached, route to a fallback executor that takes definitive action.

environment: Multi-agent LLM orchestration · tags: infinite-loop handoff failure-mode routing depth · source: swarm · provenance: https://langchain-ai.github.io/langgraph/ \(recursion\_limit configuration\)
