As we integrate LLMs and autonomous agents into our applications, the traditional boundaries of software design are breaking. We used to have human users sending commands to a system. Now, we have AI agents observing the system, communicating with users, and taking autonomous actions.

How do we model this in DDD? Is an AI agent a User? A Domain Service? An external Bounded Context? In this talk, we’ll look at the architectural implications of building "Agentic UIs" and integrating AI into the domain. We’ll explore how to model agent permissions, how to design commands that can be safely issued by non-humans, and how to use the Ubiquitous Language to prompt and constrain LLM behaviors. This is a forward-looking talk about applying rigorous domain modeling principles to the wild west of AI-driven fullstack applications.
