Interesting, I will have to check this out as a lot of what I do everyday involves asking claude and chat go use my signed in profile, I even built a skill for it with some other tools.

https://github.com/browser-use/browser-use has been great so far

When I need an coding agent to interact with an existing session I just use

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-profile-stable and tell it

This pattern of using original source code and rewrite to improve them (and get rid of technical debt) is very real. I did one for an old app in Objective C, move it to Flutter and said goodbye to my old //TODOs. And get an Android build as a bonus. :-)
