What

Plugins add features to Claude Code, and the enabledPlugins setting turns them on or off. Some built-in plugins now have new names starting with cc-plugin-, such as cc-plugin-responsive-mode. The bundled security plugin is now cc-plugin-sec-default@builtin.

To keep existing settings working:

  • Looking up, enabling or disabling a plugin now matches every spelling of a built-in plugin's name. Before, only an exact name match counted.
  • Checks for duplicate plugin names also treat the old and new spellings as the same plugin.
  • Writing enabledPlugins replaces older spellings of a plugin id instead of adding a second entry.
  • The documentation says to keep listing the security plugin as sec-default@builtin for older releases.

Why

The rename should not leave you with the same plugin listed twice, or with a plugin switched off because your settings still use its old name. Administrators who order hooks in managed settings should know that the bundled security plugin now goes by cc-plugin-sec-default@builtin.

Confirmed since Anthropic's documentation has since written up cc-plugin-sec-default@builtin, on Manage mods for your organization. "cc-plugin-sec-default@builtin": { plugins/mods/admin see the edit
