I'm not here to be critical, but the hoops you have to jump through to get Claude out of .env is more than it should be. You basically need an agent to write it if it's anything complicated, like, allow .env.example but not .env.*.

Whereas that should probably be default on instead, and this should apply to other known sensitive folders. A simpler system like .agentignore would be even better.

I like auto mode but "the agent supervises itself" is a bad compliance/safety answer on its own.
