This module deconstructs the core paradigm shift from task-oriented UX to cognition-oriented UX. You will learn why interfaces are no longer endpoints but become active "trust surfaces" where humans observe and steer autonomous reasoning. We establish the fundamental principle that in agentic systems, usability is redefined as oversight.

We introduce the key models and definitions that underpin the discipline, including the Human-Agent-System responsibility model and the cognition loop (Intent → Reason → Act → Reflect → Learn). You will leave with a clear, five-point checklist to evaluate whether a UX is truly agentic, moving from abstract theory to a concrete evaluation framework.
