Before a sandboxed command starts, Claude Code now creates the folders that must be hidden from it. If that step fails, the command does not run. You see an error saying the sandbox could not create a folder it has to hide from the command.\n\n**Why**\n\nA command now fails safely instead of running without the hiding it was supposed to have.\n\n- Area: Sandbox\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: yes"}
