What probably matters to youSection of the release
Setting the env var CLAUDE_CODE_CCR_SURFACE=tag adds a hidden default plugin marketplace, claude-tag-plugins, to plugin search and download: search requests add included_default_marketplaces: ["claude-tag-plugins"] to the request body, and the download URL builder appends included_default_marketplaces=claude-tag-plugins as a query param. With the variable unset, which is the default, neither path is taken.
