I would have expected people (maybe a small minority, but that includes myself) to have already instructed Claude to do this. It’s a trivial instruction to add to your CLAUDE.md file.
I always assumed that if I tried to tell it, that it'd say "I'm sorry, Dave. I'm afraid I can't do that"
I guess our system prompt didn't work. If folks are having to add it manually into their own Claude.md files...
It's a config setting (probably the same end result though):
