Unclear What the new server-controlled switch changes for a reader is not stated.

What

Plugins (add-ons that extend Claude Code) now record what kind of marketplace (the catalogue a plugin is installed from) they came from, in a field called marketplaceKind.

  • Plugin entries now carry marketplaceKind from their source.
  • Plugin attribution, which records which plugin something came from, now reads marketplaceKind. Before, it read only serverPluginId, marketplaceName and installationPreference.
  • An invalid marketplaceKind value is ignored, and Claude Code logs 'Ignoring plugin attribution field'.
  • marketplaceKind now marks prompt commands as coming from a plugin, the same way serverPluginId already did.

The same release also adds a new feature check named tengu_mighty_thimble. What it controls is not clear.

Why

Claude Code can now tell which kind of marketplace a plugin or plugin command came from. This makes no visible difference to how you install or use plugins.
