Hi Nick, what I found so far is that after searching the Knowledge project, I wanted to get the personality to just answer I do not know the answer to keep things only in the Knowledge project. In the end I did the knowledge search then had an expression that was (!turn.KnowledgeAgent.answer || turn.KnowledgeAgent.answer.trim() === ''). Then off that I handed to a standard node with the aiTask card, gave it instructions. In my case I told it not to answer and gave it the original question. Not sure if that would work for you, but for me if not in the knowledge answer it always went to that card
