Validating a marketplace now gives an error with the code `UNRECORDABLE_NAME` when the marketplace name or a plugin's name breaks the naming rules. The messages read \"Claude Code cannot install plugins from marketplace \u2026\" or \"Claude Code cannot install plugin \u2026\".\n\nEach part of a plugin id (plugin@marketplace) may use only:\n\n- letters a-z and A-Z\n\n- digits\n\n- \".\", \"_\" and \"-\"\n\nIt must also start with a letter or digit.\n\nThe warning about names that are not kebab-case now says when loading with `--plugin-dir` or installing from a marketplace would refuse the name. Messages also point out when a name contains a character that cannot be displayed.\n\n**Why**\n\nBefore, these names only got a warning aimed at Claude Desktop. That warning said Claude Code accepts the name, even though Claude Code could not install it.\n\n- Area: Plugins\n- Tier: Use it now\n- Useful: 2\/5\n- Signal: 1\/5"}
