Claude TestArea: what it touches
Internal ChangesKind: in v2.1.282,
Internal ChangesSection of the release
What
The built-in Claude Test plugin uses helper agents, separate Claude workers that handle part of a task in the background. These include its author, runner and explorer agents. They and two internal agents now list mcp__plugin_claude-test_browser__claude_test_show_run among the tools they are not allowed to use.
That name did not appear in Claude Code before. It points to a tool on the plugin's browser server.
Why
In practice, only the main conversation can use this tool, and none of the background agents can.

The writer flagged doubtIt is not clear what the show-run tool does, or whether the Claude Test plugin is available to everyone.
