What’s stopping the agent from doing literally any other thing in HubSpot? You know, small stuff like editing/deleting records, sensing emails, launching marketing campaigns, deleting reports, etc.
Ideally for these pursposes, I would ALWAYS use Claude Opus 4.6 for this stuff, personally I have never seen it do unintended things to that extent.
Also, when the browser opens you can supervise it doing the thing, since you can see what its doing, you can always stop it if it ever goes wrong.
