Pure UI in the Agentic Era

Opinion — commentary, not a factual news event.
Pure UI is presented as a state-only rendering approach for agent-written interfaces, where the UI is derived directly from explicit inputs like roles, plans, and feature flags. It specifically calls out feature flags as one of the explicit state inputs to cover combinations before release. Teams can render and inspect every state permutation during development instead of discovering UI issues after deployment.
Why it matters
The article revisits the idea that UI should be a pure function of state—and argues it matters for agent-written interfaces. By passing roles, plans, billing status, and feature flags explicitly, teams can render and inspect each state combination before release.
