Claude Code now refuses to install a marketplace whose name looks like one of Anthropic's own when it is not, and reports it as not found.\n\n`\/plugin marketplace list` shows such names in quotes, with the note: \"Shown in quotes: the name looks like one of Anthropic's own, and is not.\"\n\n**Why**\n\nThis is a check against impersonation. A marketplace cannot pass itself off as an official Anthropic one by choosing a similar name, and the quotes in the list make any such name easy to spot.\n\n- Area: Plugins\n- Names: `\/plugin`\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: yes"}
