For people using coding agents regularly: do you still invest time in user-level and repo-level instruction files like CLAUDE.md, AGENTS.md, etc.?
It's not a surprise that you don't expect the rules there to be followed even with less than 100 lines of changes. Yet still see folks like Karpathy post rules around with hundreds of stars.
Tell me if you're still spending the effort of trying claude.md, and are they effective, what're you writing in it.
Update: I'm more of talking about behavior rules here (coding standard, comment style, Do this and Don't do that, etc.). For facts like project directories, important doc ref, commands, sure that always helps.
