> Most browser automation tools launch a fresh, isolated browser. This one connects to the Chrome you're already running

Is this the same as what Claude in Chrome does?

I tried that for a while and since I use Firefox and Chromium, the security problem of it seeing your tabs wasn't a big deal. Fresh Chrome install, only ever used for this exact purpose. Plus you can watch it working in real (actually very slow) time so if you did point it at something risky you can take over at any point.

For actual testing of web apps though, a skill with playwright cli in headless mode is much more effective. About 1-2k context per interaction after a bit of tuning.
