What
A plugin is an add-on that extends Claude Code. A guard hook is a check that can stop a plugin from loading. When a plugin fails to load because a guard hook refused it, or because the guard itself could not be loaded, the error now includes guardHookRefused: true. Before, the error had no such field.
Why
Plugin failures caused by a guard hook can now be told apart from other load failures.
