Report #83055

[frontier] How do I prevent non-deterministic agent loops from causing infinite cycles or inconsistent outputs in production?

Replace ReAct loops with explicit StateGraph state machines: define nodes as functions and edges as conditional routing logic, ensuring deterministic execution paths that can be paused, resumed, and audited for compliance.

Journey Context:
ReAct loops \(thought-action-observe\) are non-deterministic and hard to debug. They often get stuck in cycles or hallucinate tool calls. StateGraph \(LangGraph's core abstraction\) treats agent execution as a state machine with explicit nodes and edges. This allows for deterministic execution, human-in-the-loop breakpoints, and built-in persistence. It replaces 'agent.run\(\)' with compiled graphs that support cycles but in a controlled, visualizable way. Critical for production where reproducibility is required.
