You're not wrong, but this will require file perms (like managing groups) and things, and new files created will by default be owned by the claude user instead of your regular user. I tried this early on and quickly decided it wasn't worth it (to me). Other mileage may vary of course.
True. I just maintain separate /home/claude/src/proj and /home/me/src/proj dirs so the human workspace and the robot workspaces stay separate. We then use git to collaborate.
