UnverifiedThe fail-open design ensures that even if the routing layer encounters a problem, the entire Agent will not stall but will instead fall back to the original execution path.68% similarUnverifiedCompared to the traditional plan-execute separation pattern, the greatest advantage of the ReAct paradigm lies in fault tolerance, allowing dynamic correction of subsequent plans based on tool return results.67% similarUnverifiedWhen the routing results for a certain type of request are highly concentrated, the routing layer can be removed and the model bound directly to reduce latency and scheduling costs; if routing results remain consistently dispersed, the router's dynamic decision-making should be retained.67% similarUnverified图结构相比链式架构天然支持环路，允许失败时通过条件边路由至修正节点，是实现 Agent 自我修正能力的关键基础66% similarUnverifiedDify-Plus采用增量式二开策略而非Fork重构策略，以保持与Dify上游的兼容性65% similar
