+1. 首先阅读 @statements/optimize.md，还有 @README.md 并根据其指引了解跟aide decide有关的所有信息
+2. 对aide decide开始详细设计，我将在完成设计后将所有设计文档打包交给其他开发人员进行开发，
+    - 设计文档中要有一个用于指导接手人员的入口文档，其中要说明：需要了解哪些信息、需要做什么事
+
+对开发文档完善程度的预期是：可以仅靠整套文档和可能含有的其他附属文件的内容（我将会打包aide-program目录），以此为确定目标和完整指导（aide-program/docs/ 目录下的相关文档），开始目标程序的实际开发工作，直到构建产出程序和通过测试运行（运行aide decide -h 及其一系列命令与参数）
+
+切记，非常重要：开发文档中不允许给出代码片段、实现代码，最多只能出现类型与数据结构伪代码原型、方法签名、业务逻辑流程的plantuml流程图、API约定

-1. 首先阅读 @statements/optimize.md，还有 @README.md 并根据其指引了解跟aide decide有关的所有信息
-2. 对aide decide开始详细设计，我将在完成设计后将所有设计文档打包交给其他开发人员进行开发，
-    - 设计文档中要有一个用于指导接手人员的入口文档，其中要说明：需要了解哪些信息、需要做什么事
-
-对开发文档完善程度的预期是：可以仅靠整套文档和可能含有的其他附属文件的内容（我将会打包aide-program目录），以此为确定目标和完整指导（aide-program/docs/ 目录下的相关文档），开始目标程序的实际开发工作，直到构建产出程序和通过测试运行（运行aide decide -h 及其一系列命令与参数）
-
-切记，非常重要：开发文档中不允许给出代码片段、实现代码，最多只能出现类型与数据结构伪代码原型、方法签名、业务逻辑流程的plantuml流程图、API约定
