A plugin can be installed in different scopes, meaning different places it applies: local, project, user, or managed by an organisation. Updating a plugin no longer requires you to say which scope. When none is given, Claude Code:
Checks local, then project, then user, and uses the first one that has an install.
Prefers installs that match the current directory.
Falls back to managed if none match.
Why
You can update a plugin without first working out where it was installed.
