What This Does

When you build UI with Claude, design decisions get made: spacing values, colors, depth strategy, surface elevation. Without structure, those decisions drift across sessions.

**Interface Design helps you:**

1. Craft — Principle-based design that produces professional, polished interfaces
2. Memory — Save decisions to .interface-design/system.md, load automatically
3. Consistency — Every component follows the same principles throughout the session

Make choices once. Apply them consistently.

Before & After

**Without interface-design:**

• Every session starts from scratch
• Button heights drift (36px, 38px, 40px...)
• Random spacing values (14px, 17px, 22px...)
• No consistency across components

**With interface-design:**

• System loads automatically each session
• Patterns reused (Button: 36px, Card: 16px pad)
• Spacing on grid (4px, 8px, 12px, 16px)
• Consistent depth and surface treatment throughout
