Managed settings are settings an organization sets centrally for everyone using Claude Code. A plugin turned on through managed settings now counts as organization-managed only if the marketplace it came from matches the source those managed settings declare. A marketplace is a catalog Claude Code installs plugins from.
When the source does not match, Claude Code logs a warning. The plugin's hooks then run at the same level as the user's own plugins, not at the organization level. Hooks are commands a plugin runs automatically at certain points.
A plugin delivered from a remote source does not get organization-managed status in this release. That is planned for a later release.
Administrators should check that the marketplace sources in their managed settings match where their plugins actually come from. If they don't, the organization's plugin hooks can quietly drop to the user level, and the only sign is a warning in the log.
It is not clear what information Claude Code compares when it decides whether a plugin's source matches.
