 ### Backend (Python)
 
 Follow [CLAUDE.md](./CLAUDE.md) principles:
-- Modern Python (match-case, async/await, native types)
-- Import order: builtin → 3rd party → our package (alphabetical)
-- Use `db_async` wrappers for all DB operations
-- Split large functions into smaller ones
+- Modern Python (match-case, async/await, native types like `list[]`, `dict[]`)
+- Import order: **builtin → 3rd party → ours**, then **shorter paths first**, then **alphabetical**
+  - `import os` before `from datetime import`
+  - `from kohakuhub.db import` before `from kohakuhub.auth.dependencies import`
+- **ALWAYS** use `db_async` wrappers for all DB operations (never direct Peewee in async code)
+- Split large functions into smaller ones (especially match-case with >3 branches)
+- Use `black` for code formatting
+- Type hints recommended but not required (no static type checking)
 
 ### Frontend (Vue 3)
 
 Follow [CLAUDE.md](./CLAUDE.md) principles:
-- JavaScript only (no TypeScript), use JSDoc for types
+- JavaScript only (no TypeScript), use JSDoc comments for type hints
+- Vue 3 Composition API with `<script setup>`
 - Split reusable components

+- Mobile responsive design
+- Use `prettier` for code formatting
+- UnoCSS for styling

+   - Update relevant documentation (API.md, CLI.md, etc.)
+   - Add tests for new functionality
+   - Ensure code follows style guidelines
+   - Test in both development and Docker deployment modes
+   - Run `black` on Python code
+   - Run `prettier` on frontend code
+
+2. **Submitting PR:**
+   - Create a clear, descriptive title
+   - Describe what changes were made and why
+   - Link related issues
+   - Include screenshots for UI changes
+   - List any breaking changes
+   - Request review from maintainers
+
+3. **After submission:**
+   - Address feedback promptly
+   - Keep PR focused (split large changes into multiple PRs)
+   - Rebase on main if needed
+
+## Development Workflow
+
+### Backend Development
+
+```bash
+# Start infrastructure
+docker-compose up -d lakefs minio postgres
+
+# Run backend with hot reload
+uvicorn kohakuhub.main:app --reload --port 48888
+
+# API documentation available at:
+# http://localhost:48888/docs
+```
+
+### Frontend Development
+
+```bash
+# Run frontend dev server (proxies API to localhost:48888)
+npm run dev --prefix ./src/kohaku-hub-ui
+
+# Access at http://localhost:5173
+```
+
+### Full Docker Deployment
+
+```bash
+# Build frontend and start all services
+npm run build --prefix ./src/kohaku-hub-ui
+docker-compose up -d --build
+
+# View logs
+docker-compose logs -f hub-api
+docker-compose logs -f hub-ui
+```
+
+## Best Practices
+
+### Database Operations
+
+❌ **NEVER do this:**
+```python
+async def bad_example():
+    # Direct Peewee usage in async code blocks event loop!
+    repo = Repository.get_or_none(name="test")
+```
+
+✅ **ALWAYS do this:**
+```python
+from kohakuhub.db_async import get_repository
+
+async def good_example():
+    repo = await get_repository("model", "myorg", "mymodel")
+```
+
+### Permission Checks
+
+Always check permissions before write operations:
+
+```python
+from kohakuhub.auth.permissions import check_repo_write_permission
+
+async def upload_file(repo: Repository, user: User):
+    # Check permission first
+    check_repo_write_permission(repo, user)
+
+    # Then proceed with operation
+    ...
+```
+
+### Error Handling
+
+Use HuggingFace-compatible error responses:
+
+```python
+from fastapi import HTTPException
+
+raise HTTPException(
+    status_code=404,
+    detail={"error": "Repository not found"},
+    headers={"X-Error-Code": "RepoNotFound"}
+)
+```
+
+### Logging
+
+Use the custom logger system with colored output:
+
+```python
+from kohakuhub.logger import get_logger
+
+logger = get_logger("MY_MODULE")
+
+# Log different levels
+logger.debug("Verbose debugging info")
+logger.info("General information")
+logger.success("Operation completed successfully")
+logger.warning("Something unusual happened")
+logger.error("An error occurred")
+
+# Exception handling with formatted traceback
+try:
+    risky_operation()
+except Exception as e:
+    logger.exception("Operation failed", e)
+    # Automatically prints formatted traceback with stack frames
+```
+
+**Pre-created loggers available:**
+- `logger_auth`, `logger_file`, `logger_lfs`, `logger_repo`, `logger_org`, `logger_settings`, `logger_api`, `logger_db`
+
+### Frontend Best Practices
+
+```vue
+<script setup>
+// Use composition API
+import { ref, computed, onMounted } from 'vue'
+
+// Reactive state
+const data = ref(null)
+const loading = ref(false)
+
+// Computed properties
+const isReady = computed(() => data.value !== null)
+
+// Async operations
+async function fetchData() {
+  loading.value = true
+  try {
+    const response = await fetch('/api/endpoint')
+    data.value = await response.json()
+  } catch (error) {
+    // Handle error
+  } finally {
+    loading.value = false
+  }
+}
+
+onMounted(() => {
+  fetchData()
+})
+</script>
+
+<template>
+  <!-- Always support dark mode -->
+  <div class="bg-white dark:bg-gray-900 text-black dark:text-white">
+    <div v-if="loading">Loading...</div>
+    <div v-else-if="isReady">{{ data }}</div>
+  </div>
+</template>
+```
