What it installs

Skills (2)

  • chrome-extension-messaging-tests

    Use when a Chrome extension's messages reach no listener, sendResponse never fires, a port disconnects mid-test, or a web page's access must be proven. Tests runtime.sendMessage, tabs.sendMessage, long-lived ports, externally_connectable and native messaging on a running extension.

  • playwright-extension-fixtures

    Use when writing or debugging Playwright tests for a Chromium browser extension: the persistent-context fixture that loads the extension and finds its ID, why an edit seems to have no effect (reload matrix), and popup, content-script, storage and MV3 service-worker tests.

Subagents (1)

  • extension-test-author

    Use proactively whenever a browser extension needs a test for its background service worker, content scripts, popup or options page, messaging or storage. Detects Manifest V2 or V3 and the target browser and writes one Playwright spec per behavior.
