Design systems often standardize components while leaving larger structural decisions—like settings page layout and behavior—uncaptured, causing inconsistent results even within one product. Testing this with AI agents building identical settings pages from the same component library confirmed the gap: each agent made different, reasonable choices about layout and interaction since no canonical pattern existed. Writing down explicit rules for structure, behavior, and interaction (not just components) resolved the divergence, producing consistent pages across agents.
