Unclear It is not clear when a session counts as a forwarded sandbox host, or what decides the action once the check is skipped.

What

In auto mode, a check decides whether an action can go ahead without asking you. In one kind of environment, called a forwarded sandbox host, Claude Code no longer runs that check. It leaves the decision open instead. A sandbox is a restricted environment for running commands.

Why

Permissions are settled differently in this kind of setup, so actions there do not go through auto mode's usual check.
