Under the hood

Plugin resolution now distinguishes sync-attributed plugins and enforces managed hooks-only rules.

Plugin resolution now distinguishes 'sync-attributed' plugins, which carry attributedMarketplaceName, serverPluginId, and installationPreference, from plain --plugin-dir copies. Each is checked against managed settings through a new admission function, and duplicate managed-plugin claims across session and synced copies are dropped. When an organization's managed settings restrict to hooks-only via allowManagedHooksOnly, admitted-by-lock plugins are now tagged with a managed-hooks-restricted warning.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Confirmed since Anthropic's documentation has since written up allowManagedHooksOnly, on MCP, plugins, skills, and hooks. Claude Code [managed settings](/docs/third-party/claude-desktop/code#interaction-with-claude-code%E2%80%99s-own-managed-settings) deployed on the device govern these hooks as they do in the Claude Code CLI: `disableAllHooks` turns them off… third-party/claude-desktop/extensions see the edit
