Overview

How it was set up

Claude Code (or Claude Desktop) connected to the Claude in Chrome extension via `claude --chrome` or `/chrome`. It shares the real Chrome session with approved domains.

Worth knowing

Heavy browser use burns tokens fast; the author says a $200/month Max plan is effectively required. No CI or headless support, Chrome and Edge only.
