A new OAuth scope, user:plugins, is requested for accounts with plugin access registered
When Claude Code logs in, it can now request an additional permission scope called user:plugins as part of OAuth (the login flow that grants Claude Code permission to act on your behalf). This scope is only added when a setting called PLUGINS_SCOPE_REGISTERED is turned on for the login configuration being used. The default and production login configurations now have this turned on, while configurations that use a custom client ID or an environment-variable override for the client ID do not.
This lets most users' logins pick up permission for a plugins-related feature automatically, while custom or overridden login setups are left unaffected until they're updated too.
