  • The text discusses the evolution of interfaces from UI (User Interface) for humans to API (Application Programmable Interface) for applications, and now UAI (User Agent Interface) for agents like LLMs.
  • It emphasizes the importance of designing features to be accessible and legible across all three interfaces (UI, API, UAI) without degrading any one of them.
  • Highlights the need to abstract the source of truth for feature functionality into the underlying application logic rather than embedding it in any single interface.
  • Uses the example of a reservation system's date field to illustrate how business logic (like blocking weekends) should be centralized and exposed through interfaces appropriately.
  • Stresses the distinction between centralized business logic and interface-specific presentation or interaction patterns.
