What

Claude Test is a bundled plugin for testing an app in a browser. It gains a terminal panel and supporting pieces:

  • A new "Claude Test" panel shows app start and ready states ("Starting your app…", "Opening your app…"), "Read your code", "Writing the tests…", a row per test with pass, fail or blocked marks, a progress bar, an estimate of time left, and hints such as "/claude-test fix" and "Details in the chat · ". An "Open the full report" label was also added. The command name /claude-test appears in this panel code and did not appear before.
  • Claude is told when the panel is open in the terminal and that the skill's panel rule applies, with a variant for terminals that cannot draw screenshots.
  • The build also contains a built-in plugin id claude-test@builtin, agents claude-test:runner and claude-test:explorer, run folders under .claude-test/runs, and an entry pairing claude-test with cc-plugin-claude-test.
  • A new tool, mcp__plugin_claude-test_browser__claude_test_pane_note, was added to two allow lists.
  • The built-in Playwright MCP server (the browser-control add-on) now gets CLAUDE_TEST_ESSENTIAL_TRAFFIC=1 when a condition holds. Before, it got only CLAUDE_TEST_PROJECT_DIR.
  • A "ui.blit" entry appears in a method allow list.

No gate controlling the panel was traced.

Why

Claude Test is gaining a terminal view of a test run, so progress and results can be followed without reading the chat.
