Your point is fair, but it rests on a major assumption I'd question: that the only limit lies with the user, and the tooling itself has none. What if it’s more like “you can’t squeeze blood from a stone”? That is, agentic coding may simply have no greater potential than what I've already tried. To be fair I haven't gone all the way in trying to make it work but, even if some minor workarounds exist, the full promise being hyped might not be realistically attainable.

How can one judge potential without fully understanding or having used it to its full potential?

I don’t think agentic programming is some promised land of instant code without bugs.

It’s just a force multiplier for what you can do.
