+## 언어 & 기본 원칙
+
+- **Dart Sound Null Safety** 완벽 준수 (`?`, `!`, `late` 올바르게 사용)
+- `dynamic` 타입 사용 **지양** → 명시적 타입 선언
+- 모든 주석은 **한국어**로 작성

+```
+
+---
+
+## 위젯 작성 원칙
+
+```dart
+// ✅ 좋은 예 — 작은 위젯으로 분리
+class UserProfilePage extends StatelessWidget {
+  const UserProfilePage({super.key});
+
+  @override
+  Widget build(BuildContext context) {
+    return Scaffold(
+      appBar: const _AppBar(),
+      body: const _ProfileBody(),
+    );
+  }
+}
+
+class _ProfileBody extends StatelessWidget {
+  const _ProfileBody();
+
+  @override
+  Widget build(BuildContext context) {
+    return Column(
+      children: [
+        const _AvatarSection(),
+        const _InfoSection(),
+      ],
+    );
+  }
+}
+```
+
+- 위젯 트리 depth가 깊어지면 **커스텀 위젯으로 분리**
+- `build()` 메서드 내 비즈니스 로직 작성 **금지**
+- `const` 생성자 적극 활용 (불필요한 리빌드 방지)
+
+---
+
+## 반응형 UI
+
+```dart
+// ❌ 하드코딩 금지
+Container(width: 375, height: 200)
+
+// ✅ 반응형 처리
+Container(
+  width: MediaQuery.of(context).size.width * 0.9,
+  child: ...,
+)
+
+// ✅ 유연한 레이아웃
+Expanded(flex: 2, child: LeftPanel()),
+Expanded(flex: 1, child: RightPanel()),
+```
+
+- `Expanded`, `Flexible`, `MediaQuery`, `LayoutBuilder` 적극 활용
+- 하드코딩 픽셀값 사용 **금지**
+- 폰트 크기는 `Theme.of(context).textTheme` 활용
+
+---
+
+## 상태 관리
+
+```dart
+// Riverpod 예시 (권장)
+@riverpod
+Future<User> fetchUser(FetchUserRef ref, int id) async {
+  final repo = ref.watch(userRepositoryProvider);
+  return repo.getUser(id);
+}
+
+// 위젯에서 사용
+class UserWidget extends ConsumerWidget {
+  @override
+  Widget build(BuildContext context, WidgetRef ref) {
+    final userAsync = ref.watch(fetchUserProvider(userId));
+    return userAsync.when(
+      data: (user) => Text(user.name),
+      loading: () => const CircularProgressIndicator(),
+      error: (e, _) => const ErrorWidget(),
+    );
+  }
+}
+```
+
+- **Riverpod** 권장 (Provider는 레거시로 간주)
+- `StatefulWidget`은 애니메이션, 폼 등 로컬 UI 상태에만 제한적 사용
+
+---
+
+## API 통신 (Dio + 인터셉터)
+
+```dart
+// core/network/dio_client.dart
+class DioClient {
+  late final Dio _dio;
+
+  DioClient() {
+    _dio = Dio(BaseOptions(baseUrl: Env.apiUrl));
+    _dio.interceptors.add(AuthInterceptor());   // 토큰 자동 첨부
+    _dio.interceptors.add(ErrorInterceptor());  // 에러 코드 처리
+  }
+}
+
+// 에러 인터셉터 — CLAUDE.md 에러 맵 기준 한국어 메시지 처리
+class ErrorInterceptor extends Interceptor {
+  @override
+  void onError(DioException err, ErrorInterceptorHandler handler) {
+    // 에러 코드 파싱 후 SnackBar/Dialog 표시
+  }
+}
+```
+
+---
+
+## 보안 (토큰 저장)
+
+```dart
+// flutter_secure_storage 사용
+const storage = FlutterSecureStorage();
+
+// 저장
+await storage.write(key: 'access_token', value: token);
+
+// 읽기
+final token = await storage.read(key: 'access_token');
+
+// 삭제 (로그아웃)
+await storage.deleteAll();
+```
+
+- JWT, 민감 정보는 반드시 `flutter_secure_storage` 사용
+- `SharedPreferences`에 토큰 저장 **금지**
+
+---
+
+## 성능 & 최신 트렌드 추가 규칙
+
+- **모델 직렬화**: `json_serializable` + `freezed` 사용 권장 (불변 모델)
+- **이미지**: `cached_network_image`로 네트워크 이미지 캐싱
+- **목록**: 긴 목록은 `ListView.builder` 사용 (전체 렌더링 금지)
+- **에러 핸들링**: `Either<Failure, Success>` 패턴 고려 (`fpdart` 패키지)
+- **라우팅**: `go_router` 사용 권장 (딥링크, 중첩 라우팅 지원)
+- **환경 분리**: `--dart-define` 또는 `flutter_dotenv`로 dev/prod 분리

+
+## 아키텍처 원칙
+
+### 관심사 분리 (Separation of Concerns)
+
+```
+Controller  →  HTTP 라우팅, 요청/응답 파싱만 담당
+Service     →  모든 비즈니스 로직 처리
+Repository  →  데이터 접근 계층 (TypeORM)
+DTO         →  요청/응답 데이터 형식 정의 및 검증
+```
+
+- `Controller`에 비즈니스 로직 작성 **금지**
+- `new` 키워드로 수동 객체 생성 **지양** → 의존성 주입(DI) 활용
+
+### 모듈 구조
+
+```

+```
+
+---
+
+## DTO 작성 규칙
+
+```typescript
+import { IsString, IsEmail, IsNotEmpty, MinLength } from 'class-validator';
+import { ApiProperty } from '@nestjs/swagger';
+
+export class CreateUserDto {
+  @ApiProperty({ description: '사용자 이메일', example: 'user@example.com' })
+  @IsEmail({}, { message: '올바른 이메일 형식을 입력해 주세요.' })
+  @IsNotEmpty()
+  email: string;

+  @ApiProperty({ description: '비밀번호 (최소 8자)', example: 'password123' })
+  @IsString()
+  @MinLength(8, { message: '비밀번호는 최소 8자 이상이어야 합니다.' })
+  password: string;
+}
+```
+
+- 모든 DTO는 `class-validator` + `class-transformer` 사용
+- 에러 메시지는 **한국어**로 작성
+- `@ApiProperty()` 반드시 포함 (Swagger 명세용)
+
+---
+
+## 표준 응답 인터셉터
+
+```typescript
+// common/interceptors/response.interceptor.ts
+@Injectable()
+export class ResponseInterceptor implements NestInterceptor {
+  intercept(context: ExecutionContext, next: CallHandler): Observable<any> {
+    return next.handle().pipe(
+      map((data) => ({
+        success: true,
+        data,
+      })),
+    );
+  }
+}
+```
+
+- `main.ts`에서 전역 등록: `app.useGlobalInterceptors(new ResponseInterceptor())`
+
+---
+
+## 전역 Exception Filter
+
+```typescript
+// common/filters/http-exception.filter.ts
+@Catch()
+export class AllExceptionsFilter implements ExceptionFilter {
+  catch(exception: unknown, host: ArgumentsHost) {
+    const ctx = host.switchToHttp();
+    const response = ctx.getResponse<Response>();
+
+    // 에러 코드 매핑 로직 포함
+    // SYS_001 / AUTH_001 / VAL_001 등 CLAUDE.md 에러 맵 참조
+  }
+}
+```
+
+---
+
+## Swagger 필수 적용
+
+```typescript
+// main.ts
+const config = new DocumentBuilder()
+  .setTitle('API 문서')
+  .setDescription('프로젝트 API 명세서')
+  .setVersion('1.0')
+  .addBearerAuth()
+  .build();
+
+const document = SwaggerModule.createDocument(app, config);
+SwaggerModule.setup('api-docs', app, document);
+```
+
+- 모든 Controller에 `@ApiTags()` 적용
+- 모든 엔드포인트에 `@ApiOperation()`, `@ApiResponse()` 작성
+- 모든 DTO에 `@ApiProperty()` 작성
+
+---
+
+## 인증 (JWT)
+
+- Access Token: 만료 시간 짧게 (15분 ~ 1시간)
+- Refresh Token: HttpOnly Secure 쿠키로 전달
+- `@nestjs/jwt` + `@nestjs/passport` 사용
+- Guard를 통한 라우트 보호
+
+---
+
+## 성능 & 최신 트렌드 추가 규칙
+
+- **캐싱**: 자주 조회되는 데이터는 `@nestjs/cache-manager` (Redis) 활용 고려
+- **Rate Limiting**: `@nestjs/throttler`로 API 남용 방지
+- **Pagination**: 목록 API는 반드시 커서 기반 또는 오프셋 페이지네이션 적용
+- **Logging**: `winston` 또는 `@nestjs/common Logger` 사용, `console.log` 지양
+- **Health Check**: `@nestjs/terminus`로 `/health` 엔드포인트 구성 권장
+- **Versioning**: API 버전 관리 (`/v1/`, `/v2/`) 적용 고려

+
+## 컴포넌트 작성 원칙
+
+### 필수 구조
+
+```vue
+<script setup lang="ts">
+// 1. import
+// 2. Props / Emits 정의
+// 3. Store / Composable 호출
+// 4. 반응형 상태 (ref, reactive, computed)
+// 5. 함수 정의
+// 6. Lifecycle Hooks
+// 7. watch
+</script>
+
+<template>
+  <!-- 시맨틱 HTML 태그 사용 -->
+</template>
+
+<style scoped>
+/* rem 단위 사용, 인라인 스타일 금지 */
+</style>
+```
+
+- `Options API` 사용 **금지** → `Composition API` + `<script setup>` 필수
+- 인라인 스타일(`style=""`) 사용 **금지** → `<style scoped>` 사용
+- 모든 px 값은 **rem으로 변환** (기준: 16px = 1rem)
+
+---
+
+## Props / Emits 타입 정의
+
+```typescript
+// Props
+interface Props {
+  title: string
+  count?: number
+  items: string[]
+}
+const props = withDefaults(defineProps<Props>(), {
+  count: 0,
+})
+
+// Emits
+interface Emits {
+  (e: 'update', value: string): void
+  (e: 'close'): void
+}
+const emit = defineEmits<Emits>()
+```
+
+---
+
+## 상태 관리 (Pinia)
+
+```typescript
+// stores/user.store.ts
+export const useUserStore = defineStore('user', () => {
+  // 상태
+  const user = ref<User | null>(null)
+  const isLoggedIn = computed(() => !!user.value)
+
+  // 액션
+  async function fetchUser(id: number) {
+    // API 호출
+  }
+
+  return { user, isLoggedIn, fetchUser }
+})
+```
+
+- 도메인별 Store 파일 분리 (`user.store.ts`, `auth.store.ts` 등)
+- Store 내 API 호출은 허용, 단 에러 처리는 인터셉터에 위임
+
+---
+
+## API 호출 (Composables + Axios)
+
+```typescript
+// composables/useApi.ts — 중앙 Axios 인스턴스
+const api = axios.create({
+  baseURL: import.meta.env.VITE_API_URL,
+  withCredentials: true, // HttpOnly 쿠키 전송
+})
+
+// 응답 인터셉터 — 에러 코드 전역 처리
+api.interceptors.response.use(
+  (response) => response.data.data, // success: true → data 언래핑
+  (error) => {
+    const code = error.response?.data?.error?.code
+    // 에러 코드별 Toast 알림 처리 (CLAUDE.md 에러 맵 참조)
+    return Promise.reject(error)
+  },
+)
+```
+
+```typescript
+// composables/useUser.ts — 도메인별 API Composable
+export function useUser() {
+  const loading = ref(false)
+  const error = ref<string | null>(null)
+
+  async function getUser(id: number) {
+    loading.value = true
+    try {
+      return await api.get(`/users/${id}`)
+    } finally {
+      loading.value = false
+    }
+  }
+
+  return { loading, error, getUser }
+}
+```
+
+- API 호출 로직은 반드시 `composables/` 폴더에 분리
+- 컴포넌트 내 `axios.get()` 직접 호출 **금지**
+
+---
+
+## 라우터 (Vue Router)
+
+```typescript
+// 코드 스플리팅 — 모든 페이지 컴포넌트는 lazy import
+const routes = [
+  {
+    path: '/dashboard',
+    component: () => import('@/pages/DashboardPage.vue'),
+    meta: { requiresAuth: true },

+  }
+})
+```
+

+
+## 성능 & 최신 트렌드 추가 규칙

+- **컴포넌트 분리**: 200줄 이상 컴포넌트는 분리 고려
+- **`defineAsyncComponent`**: 무거운 컴포넌트는 비동기 로딩 적용
+- **`v-memo`**: 반복 렌더링 최적화 필요 시 활용
+- **`<Suspense>`**: 비동기 컴포넌트 로딩 상태 처리에 활용
+- **환경변수**: 모든 설정값은 `import.meta.env.VITE_*` 형태로 관리
