PHASE 3: New Patterns (Critical Mass = 15+)

Status: ✅ COMPLETE Goal: Enough patterns that this feels like a real library, not a demo

Overview

Add 8 new patterns to reach 15+ total patterns, each with complete implementation.

Patterns to Add

# Pattern Status Why
1 ChatMessage ✅ COMPLETE Every AI app needs this. Bubbles, streaming text, avatars.
2 CommandPalette ✅ COMPLETE ⌘K menu. High-value, high-wow, everyone wants one.
3 KanbanBoard ✅ COMPLETE Drag-and-drop columns. Visual, screenshot-worthy.
4 Timeline ✅ COMPLETE Event/activity feeds. Common in dashboards.
5 Sidebar ✅ COMPLETE Navigation pattern. Every app needs one.
6 StatsGrid ✅ COMPLETE Multiple MetricCards in a responsive grid layout with header.
7 ConfirmDialog ✅ COMPLETE AI action confirmation. "Are you sure you want to delete 47 rows?"
8 CodeBlock ✅ COMPLETE Syntax-highlighted code display. For dev tool UIs.

Each Pattern Ships With

  • component.tsx — the component
  • schema.ts — Zod schema with LLM descriptions
  • example.tsx — usage example
  • prompt.md — the prompt that makes any LLM generate this pattern correctly
