Our HubSpot import seed skills have strong always on prompts for asking user before doing any action, and it knowing where to click. For actions faster than browser, the skill also knows how to use hubspot cli.

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.
