+| `hooks/` | Server data fetching functions | `hooks/AGENTS.md` |
+| `lib/` | Core utilities & validation | `lib/AGENTS.md` |
+
+## FOR AI AGENTS
+
+### When Adding New Features
+
+1. **Pages**: Add to `app/[locale]/` following locale pattern
+2. **API**: Add to `app/api/` with Zod validation
+3. **Components**: Add to appropriate domain folder
+4. **Translations**: Update BOTH `zh.json` AND `en.json`
+
+### Common Patterns
+
+- **Locale routing**: `middleware.ts` handles locale detection
+- **Data fetching**: Use functions from `hooks/` in Server Components
+- **Validation**: All schemas in `lib/validations.ts`
+- **Styling**: Neo-brutalism with Tailwind (see `components/AGENTS.md`)
