What probably matters to youSection of the release
What

The --marketplace <source> option installs a plugin by its bare name from the marketplace at a given source: an owner/repo, a git or https URL, or a path. Claude Code now checks how you used it and gives a usage error when:

  • the source is missing, or starts with a dash
  • you did not give exactly one plugin name
  • the plugin name already includes @marketplace

In that last case, name the marketplace once only, either as <plugin>@<marketplace> or with --marketplace. A marketplace that has not been added yet is added first, in your user settings, under the same checks as plugin marketplace add.

Why

A mistyped install command now tells you what to fix instead of failing in a less obvious way.

Added since A small documentation edit on Error reference touched a line naming --marketplace after this was published. You named a new marketplace source with [`--marketplace <source>` on the install command](/docs/en/plugins/install#add-a-marketplace-and-install-in-one-command), in a session or from your shell. The catalog Claude Code fetched from that so… errors see the edit
