  • Maintains existing data flow and state management
  • Preserves existing permission system
  • Advanced options hidden but accessible
  • Backward compatible with current architecture

Integration Points:

<SkillsMarketplace
  installedSkills={existing skill extensions}
  enabledSkills={workspace-enabled skills}
  onToggleSkill={existing toggle handlers}
  onInstallCustomSkill={new custom skill dialog}
  isLoading={existing loading states}
/>

Transformation Results

Before (Technical UI)

❌ Empty skills list
❌ Complex permission matrix
❌ Employee override dropdowns
❌ Technical jargon
❌ Manual installation only
❌ No skill discovery
❌ Dense, overwhelming interface

After (User-Friendly Marketplace)

✅ 20 pre-loaded useful skills
✅ One-click enable/disable
✅ Card-based visual interface
✅ Clear descriptions and tool lists
✅ Smart search and filtering
✅ Rich skill discovery
✅ Intuitive, modern design
