+```
+
+### Testing
+```bash
+pnpm test         # Run Vitest unit tests
+pnpm test:e2e     # Run Playwright E2E tests
+```
+
+### Database
+```bash
+pnpm prisma migrate dev   # Run database migrations
+pnpm prisma migrate dev --name init    # Create initial migration

+
+## Architecture Overview
+
+This is a **Next.js 15 multilingual AI project navigation website** using the App Router architecture with the following key components:
+
+### i18n Architecture (next-intl)
+- **Locales**: `zh` (default) and `en`
+- **Route pattern**: `/{locale}/path` (always prefixed with locale)
+- **Middleware**: `src/middleware.ts` handles locale detection and routing
+- **i18n config**: `src/i18n/request.ts` loads locale messages from `src/messages/{locale}.json`
+- **Messages**: Translation files at `src/messages/zh.json` and `src/messages/en.json`
+
+### App Router Structure
+```
+src/app/
+├── [locale]/           # Locale-scoped routes
+│   ├── page.tsx        # Home page
+│   ├── projects/       # Projects listing
+│   └── layout.tsx      # Locale layout (header, footer)
+├── api/                # API routes (no locale prefix)
+│   └── webhook/projects/route.ts  # Webhook for project ingestion
+└── layout.tsx          # Root layout
+```
+
+### Database (Prisma + PostgreSQL)
+- **Schema**: `prisma/schema.prisma` defines models: `Project`, `Tag`, `ExternalLink`
+- **Enums**: `ProjectStatus` (ACTIVE/ARCHIVED), `LinkType` (WEBSITE/GITHUB/HUGGINGFACE/PAPER)
+- **Client singleton**: `src/lib/prisma.ts` exports Prisma client instance
+- **Multilingual fields**: Most models have `name`/`nameEn`, `description`/`descriptionEn` pairs
+
+### Webhook Deduplication Strategy
+The webhook at `src/app/api/webhook/projects/route.ts` implements a **multi-level deduplication** strategy to prevent duplicate projects:
+1. **GitHub URL exact match** (highest priority)
+2. **Website URL exact match**
+3. **slug match** (fallback)
+
+### Validation (Zod)
+- **Schemas**: `src/lib/validations.ts` defines all Zod schemas
+- `ProjectInputSchema`: Validates incoming project data
+- `WebhookPayloadSchema`: Validates webhook requests with API key
+- `ProjectQuerySchema`: Validates query parameters
+
+### Styling (Tailwind CSS)
+- **Neo-brutalism design**: Sharp corners, bold borders, hard shadows
+- **Theme colors**: Primary gold (#FFD700), secondary orange, custom shadows (shadow-neo, shadow-brutal)
+- **Dark mode**: Class-based with `dark:` prefix
+- **Config**: `tailwind.config.ts` extends theme with custom colors, shadows, and animations
+
+### UI Components
+- **Radix UI primitives**: `@radix-ui/react-slot`, `@radix-ui/react-navigation-menu`, `@radix-ui/react-dropdown-menu`
+- **Lucide React icons**: Used throughout the app
+- **Custom components**: `src/components/` organized by domain (project/, locale/, search/)
+
+## MCP Servers Usage (按需使用)
+
+1. **context7**: 不确定 API 用法时查阅最新文档
+2. **chrome-devtools-mcp**: 查看页面效果、调试 UI 修复 BUG
+3. **dbhub mcp**: 查询数据库数据（PostgreSQL）
+4. **shadcn mcp**: 确认 shadcn/ui 组件用法
+5. **web-search-prime**: 默认联网搜索工具
+6. **vision-mcp-server**: 图片/视频理解
