Report #26204
[frontier] Rigid DAG orchestration breaks when agent steps fail or require dynamic replanning
Use an event-driven, iterative loop \(ReAct/Plan-and-Solve\) with dynamic replanning rather than a static Directed Acyclic Graph \(DAG\) for complex agent workflows.
Journey Context:
DAG-based orchestration is great for deterministic pipelines but fails for autonomous agents that need to adapt to unexpected tool failures or new information. If a tool fails in a rigid DAG, the workflow halts. The emerging pattern is the 'Agent Loop' where the LLM acts as a dynamic router. If a tool fails, the LLM can decide to try a different tool, alter its plan, or ask for help, rather than just throwing an error. State machines or event loops allow the agent to maintain a high-level plan while dynamically adjusting the execution path.
