I'm not sure I agree.
It's easy to "give" instructions, but Claude routinely "forgets" to follow certain instructions, such as "always using the Edit Tool".
Just this week it started to use bash with string concatenation to work around some commands that were blocked in settings.json
That's what I meant - you give it an instruction that seems to work (always ask before deploy) and so you trust it, and then you notice it can easily convince itself to deploy without authorization ("the user asked me to fix this, and they must know it's a deploy ...").
It plays itself.
What seems to work for me is automation - read file hook that re-injects instructions in the prompt every 15 minutes. Switch on the filename and get language-specific instructions too.
Ever since they made auto-mode default I swear claude has tuned to use python commands instead of the Edit Tool to frustrate the ~security conscience~ luddites into using auto-mode.
