shadcn on agent-era UI: interfaces can differ, but behavior guarantees must match
shadcn · x · 2026-11-15
shadcn, creator of shadcn/ui, lays out the core idea behind the UI SDK he's building: users and agents don't need identical interfaces — they need identical interface behaviors.
Agents may generate wildly different UIs: yours might render a calendar for date picking, another might use a simple input field, others might do something entirely different. That's fine. What matters is that the underlying guarantees stay the same — and that's exactly what the SDK is designed to provide.
