Agent = Model + Harness.
Different AI workflows don’t require different interfaces.
The separation is straightforward:
🧠 Model → Determines the interaction and supplies context.
⚙️ Harness → Validates requests, manages state and executes actions.
🧩 UI → Renders the appropriate reusable component.
Three workflows. One option picker. Different choices.
The model decides what interaction is needed. The application controls how it behaves.
That’s how you build flexibility without sacrificing predictability.
