I found that helpful for a question but the btw query seemed to go to a subagent that couldn't interrupt or direct the main one. So it really was just for informational questions, not "hey what if we did x instead of y?"
Yesterday it was showing a hint in the corner to use "/btw" but when I first tried it I got this same error. About ten minutes later (?) I noticed it was still showing the same hint in the corner, so I tried it again and it worked. Seemed to be treated as a one-off question which doesn't alter the course of whatever it was already working on.
It's not really the same use case. It's a smaller model, it doesn't have tools, it can't investigate, etc. The only thing it can do is answer questions about whatever is in the current context.
