Unclear It is not clear which parts of Claude Code use this check or when it applies.
What
The sandbox is a fenced-off area that limits which folders Claude Code is allowed to write to. A new check can now withhold Claude Code's own file creations and deletions when they fall outside those allowed folders.
Why
This is new sandbox behaviour. In practice, a file Claude Code tries to create or delete outside the permitted folders may not go through.
