A plugin is a bundle of extra abilities Claude Code can load.\n\n- It registers a `claude-test` command and a skill hook, and connects a browser helper MCP server (an add-on that gives Claude tools to drive a browser).\n\n- When it fails to start, it now shows a specific fix, for example \"Claude Test did not start: its browser helper is switched off for this project.\"\n\n- It records draft and run usage from `saved.json` and `results.json`.\n\n- If another copy of `claude-test` is installed, the message now says to disable or uninstall that one on the Installed tab of `\/plugin`, keep the built-in one on, and restart Claude Code. Before, it pointed to the other copy's marketplace name and asked for a new session.\n\n- The message saying Claude Test needs an interactive Claude Code session in a terminal, and the \"Claude Test cannot run in this session yet\" message, are gone from where they were.\n\n**Why**\n\nIf Claude Test fails to start, the error now says what to change. The findings suggest it may no longer be limited to interactive terminal sessions.\n\n- Area: Claude Test\n- Names: `claude-test`\n- Tier: Use it now\n- Useful: 5\/5\n- Signal: 4\/5"}
