Error Message

When a Skill tool is invoked in a session running in Bypass Permissions mode, the session automatically downgrades to Accept Edits mode. The error banner reads: "Bypass Permissions mode isn't enabled. The session started in Accept Edits — enable Bypass Permissions in Settings to use it."

Error Messages/Logs

Mode switches to "Accept Edits" and error banner appears Workaround: Add drv-brain script patterns to permissions.allow in project settings.json — commands run without prompts even in Accept Edits mode, but the mode switch and error banner remain.

Root Cause

Root cause (from app source): The CLI subprocess checks whether --dangerously-skip-permissions is available and emits bypass_permissions_gate_blocked when not in a Docker/sandbox container. The app's Redux store catches this event and downgrades the session mode.

What Should Happen?
