What
Managed settings are settings an administrator sets for everyone on a machine or in an organisation, stored in files such as managed-settings.json and the managed-settings.d/ folder. Claude Code now has a list of protected paths that includes the managed settings folder, managed-settings.d/ and the policy settings paths.
The check that decides whether Claude may write to a file also has a new early step that can give an answer before the rest of the check runs.
Why
This could stop Claude from editing managed settings files.
