-## 代码风格
-
-### 类注解顺序
-```java
-@Slf4j
-@Service  // 或 @Component, @RestController
-@RequiredArgsConstructor(onConstructor = @__(@Autowired))
-public class XxxServiceImpl implements XxxService {
-```
-
-### Controller 规范
-- 使用 `@Api(tags = "模块名")` 标注 Swagger 分组
-- 使用 `@ApiOperation(value = "接口描述")` 标注接口
-- 使用 `@ResponseStatus` 指定 HTTP 状态码
-- 使用 `@Valid` 进行参数校验
-
-### Service 规范
-- 接口定义在 `service/` 目录
-- 实现类在 `service/impl/` 目录，命名为 `XxxServiceImpl`
-- gRPC 客户端封装在 `service/client/` 目录，命名为 `XxxServiceRpcClient`
-
-### 配置常量
-- 配置项定义在 `ConfigConstants` 接口中
-- 使用 `@Value(ConfigConstants.XXX)` 注入配置
-
-### 依赖注入
-- 优先使用构造器注入：`@RequiredArgsConstructor(onConstructor = @__(@Autowired))`
-- 配置值使用 `@Value` 注入
-
-### 日志规范
-- 使用 `@Slf4j` 注解
-- 使用 `log.info/warn/error` 记录日志
-- 异常日志使用 `log.error("message", e)`
-
-### gRPC 调用
-- 通过 `XxxServiceRpcClient` 封装 gRPC 调用
-- 在 `GrpcConfig` 中配置 Channel 和 Stub
-
-### 定时任务
-- 放在 `logic/task/` 目录
-- 使用 `@Scheduled(cron = "...")` 注解
-- 使用 `@Component` 注册为 Bean
-
-## 命名规范
-- DTO 类：`XxxDTO` 或内部类 `XxxDTO.CreateXxxDTO`
-- VO 类：`XxxVO`
-- 枚举类：`XxxEnum`
-- 常量类：`XxxConstants`
-- 工具类：`XxxUtil`
-
-## 禁止事项
-
-### 禁止循环依赖
-- **Service 之间禁止循环调用**：ServiceA 调用 ServiceB，ServiceB 不能再调用 ServiceA
-- **避免循环依赖注入**：如果出现循环依赖，需要重构代码，提取公共逻辑到新的 Service
-- **分层调用原则**：Controller → Service → RpcClient/Store，禁止反向调用
-
-### 禁止循环调用 gRPC 方法
-- **禁止在循环中调用 gRPC 方法**：会导致大量网络请求，严重影响性能
-- **必须使用批量接口**：如果需要处理多条数据，必须使用批量查询/批量创建接口
-- **先收集 ID 再批量查询**：先收集所有需要查询的 ID，一次性批量查询
-
-```java
-// ❌ 错误示例：循环调用 gRPC
-for (Long id : ids) {
-    var result = rpcClient.getById(id);  // 禁止！
-    results.add(result);
-}
-
-// ✅ 正确示例：批量调用
-var results = rpcClient.getByIds(ids);  // 一次批量查询
-```
-
-### 批量接口设计规范
-- **Proto 定义批量方法**：`GetXxxsByIds`、`BatchCreateXxx`、`BatchUpdateXxx`
-- **RpcClient 封装批量方法**：提供 `getByIds(List<Long> ids)` 等批量方法
-- **空集合检查**：批量方法调用前检查集合是否为空，避免无效请求
-
-### 参数类型规范
-- **禁止使用 Object 作为参数类型**：必须明确定义具体类型
-- **禁止使用 Map<String, Object>**：应定义具体的 DTO 类
-- **集合类型必须指定泛型**：使用 `List<XxxDTO>` 而非 `List`
-- **方法参数类型要明确**：避免使用 `var` 定义方法参数
-- **返回值类型要明确**：禁止返回 `Object`，必须定义具体类型
-
-### 示例
-```java
-// ❌ 错误示例
-public Object process(Map<String, Object> params) { ... }
-
-// ✅ 正确示例
-public OrderVO process(CreateOrderDTO params) { ... }
-```

-# 项目技术栈
+# Backend Implementation Skill (Spring Boot + gRPC)
 
 
-## 核心框架
-- **Spring Boot 2.5.12**：Web 应用框架
-- **Java 17**：编程语言
-- **Gradle**：构建工具
+## When writing backend code
+- Use Spring Boot 2.5.12 conventions
+- Write Java 17 compatible code
+- Follow layered architecture
 
 
-## 通信协议
-- **gRPC**：微服务间通信，使用 Protobuf 定义接口
-- **REST API**：对外 HTTP 接口，使用 Knife4j/Swagger 文档
+## Service Implementation
+- Service interfaces in service/
+- Implementations in service/impl/, named XxxServiceImpl
+- Use constructor injection
+- Use @Transactional for write operations
+- Log key business steps with @Slf4j
 
 
-## 数据存储
-- **Redis (Lettuce)**：缓存、分布式锁、Session 存储
-- **Redisson**：分布式锁实现
-- **阿里云 OSS**：文件存储
+## gRPC Integration
+- Use XxxServiceRpcClient to wrap gRPC calls
+- Prefer batch RPC methods
+- Validate empty collections before calling RPC
 
 
-## 认证授权
-- **Sa-Token + JWT**：用户认证和权限管理
-
-## 工具库
-- **Lombok**：简化 Java 代码
-- **Hutool**：通用工具类
-- **Jackson**：JSON/XML 序列化
-- **Apache POI**：Excel 处理
-
-## 可观测性
-- **Zipkin Brave**：分布式链路追踪
-- **Spring Actuator**：健康检查和监控
-
-## 异步处理
-- **Spring Scheduling**：定时任务
-- **Spring Async**：异步执行
-- **WebSocket**：实时通信
+## Common Libraries
+- Lombok for boilerplate reduction
+- Hutool for date, collection, string utilities
