+|----------------------|---------------------------------------------------------------------|
+| `azure.go`           | 定义与 Azure 相关的全局常量，如 `AzureNoRemoveDotTime`（控制删除 `.` 的截止时间）。         |
+| `cache_key.go`       | 缓存键格式字符串及 Token 相关字段常量，统一缓存命名规则。                                    |
+| `channel_setting.go` | Channel 级别的设置键，如 `proxy`、`force_format` 等。                          |
+| `context_key.go`     | 定义 `ContextKey` 类型以及在整个项目中使用的上下文键常量（请求时间、Token/Channel/User 相关信息等）。 |
+| `env.go`             | 环境配置相关的全局变量，在启动阶段根据配置文件或环境变量注入。                                     |
+| `finish_reason.go`   | OpenAI/GPT 请求返回的 `finish_reason` 字符串常量集合。                           |
+| `midjourney.go`      | Midjourney 相关错误码及动作(Action)常量与模型到动作的映射表。                            |
+| `setup.go`           | 标识项目是否已完成初始化安装 (`Setup` 布尔值)。                                       |
+| `task.go`            | 各种任务(Task)平台、动作常量及模型与动作映射表，如 Suno、Midjourney 等。                     |
+| `user_setting.go`    | 用户设置相关键常量以及通知类型(Email/Webhook)等。                                    |
+
+## 使用约定
+
+1. `constant` 包**只能被其他包引用**（import），**禁止在此包中引用项目内的其他自定义包**。如确有需要，仅允许引用 **Go 标准库**。
+2. 不允许在此目录内编写任何与业务流程、数据库操作、第三方服务调用等相关的逻辑代码。
+3. 新增类型时，请保持命名语义清晰，并在本 README 的 **当前文件** 表格中补充说明，确保团队成员能够快速了解其用途。
+
+> ⚠️ 违反以上约定将导致包之间产生不必要的耦合，影响代码可维护性与可测试性。请在提交代码前自行检查。
