AI can plan digitally. But who executes physically?

I work in real estate (I’m not a developer), and I’ve been thinking about something:

AI agents can analyze and decide digitally — but they can’t physically interact with the real world.

So I ran a small personal experiment: I structured a very simple JSON-based workflow (request → acceptance → delivery) to understand how a human operator could integrate inside an agent architecture.

I don’t believe this is the final protocol — platforms will likely define that.

But I wanted to understand the problem from the physical side before standards exist.

Open question for those building agents:

What do you actually expect from the “physical world”?

A marketplace? A protocol? A human API?

I’m exploring how a real-world operator could fit into that future architecture.
