so creators on 100x will create well defined workflows that others can reuse. If a workflow is not found, llm creates one on the go and saves it.

That sounds good, save the LLM generated workflows and have them edited by more seasoned users.

Or you could go one step further and create a special workflow which would allow you to define some inputs and iterate with an LLM until the user gets what he wants but for this you would need to generate outputs and have the user validate what the LLM has created before finally saving the recipe.
