I keep it on for my web chats, but I think I dislike it more than it helps. I'll ask a question about something and it'll find a way to tie it back to something from three months ago thinking it was a deep project I was working on, instead of what it really was: an inane question I was curious about.

I turn it off for local agents because I bounce around a few and I really don't like the mostly implicit nature of it. I want to write my instructions in version control if I have anything to say consistently to an agent.
