Unclear It is not confirmed that the sandbox settings go through this new handling in every case.
What
Managed settings are rules an administrator enforces on Claude Code. When one of these values is invalid, Claude Code now replaces it with its most restrictive value and says so: "…treating it as X, its restrictive value, until it is fixed." Before, this only covered certain top-level settings. It now also reaches nested blocks: permissions, autoMode and the sandbox settings.
defaultMode is set to "default" rather than removed
A bad entry in a list is dropped on its own, leaving the rest
A setting set to null is reported as removed
A block that is not a proper object has its locks set to their most restrictive values
Why
A typo in an administrator's deny list can no longer quietly leave the matching allow rules in effect. A mistake in the policy now makes Claude Code more restricted, not less.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Added sinceA small documentation edit on Configure auto mode touched a line naming autoMode after this was published.Set `autoMode.classifyAllShell` to `true` to suspend every Bash and PowerShell allow rule while auto mode is active, so the classifier evaluates every shell command regardless of your allow list, except [critical-path removals](/docs/en/pe…auto-mode-configsee the edit
Confirmed sinceAnthropic's documentation has since written up autoMode, on Configure auto mode.The classifier doesn't read `autoMode` from project settings in `.claude/settings.json` or `.claude/settings.local.json`.
