### 1. Is this request related to a challenge you're experiencing? Tell me about your story.

Add a conditional retry feature to workflow nodes. For example, allow writing custom functions to decide whether to retry. This could be used to check whether the output is empty, whether the output JSON is correct and can be parsed normally, or whether the output result is complete based on certain markers. In this way, users can decide under which circumstances a retry is needed according to their own requirements, and each node can be defined independently for greater flexibility. I hope such a feature can be added.
