This gives Claude direct CLI control over your actual Chrome browser, including reusing your existing login sessions so you don't need to handle auth. It's built around a structured DOM inspection command that returns elements with numbered indices, then you click/type/select by number. The workflow is optimized for token efficiency: state inspection is instant and free, screenshots cost vision tokens and should be avoided unless the user needs a saved image. Commands chain with && to minimize round trips. The real utility is in the network inspector for discovering JSON APIs and the sedimentation feature that lets you save successful automation sequences as reusable TypeScript adapters. Best for web scraping, form automation, or any task where you need to interact with sites that require authentication.
