Uninstalling after 5 minutes of discussing with the agent. It insits that it can't do browser automation, but is only a planning assistant and code generator.

It sucks. First, it can't finished the task if you don't really describe your stop conditional, even some easy task. Then, it can't output with excel format when ask it to do that. Thirdly, it only get a part of data, not all of them.

Tried it twice and it errored out both times. Maybe in latter versions it will be ready for prime time.
