Tool lets AI agents drive your already-logged-in Chrome profile via a cloned session
Browser automation tools used by agents typically start from an empty profile, so they often hit login screens even when the user is already signed in elsewhere. The open-source browser-automate skill for Claude Code and Cursor works around this by copying one Chrome profile's cookies and preferences into a temporary folder and launching a second Chrome on that copy with a DevTools port for Playwright to connect to. Because the clone runs on the same Mac and macOS user, Chrome can decrypt the cookies with its existing Keychain key, letting the copy open already signed in while the everyday window stays open. The skill requires macOS, Google Chrome, Node 18 or newer, Python 3, and the Playwright npm package, and it deletes the temporary copy after each run because it holds live session cookies. The clone is not uploaded anywhere and only functions on the same Mac and user account.
