安装：
brew install tree
使用：
tree .> tr.txt #为当前文件夹创建目录，并保存为tr.txt文件。
延伸：可以输出项目结构，为cursor等大模型指路，方便大模型理解项目和携带项目结构给大模型。
创建一个MDC文件：
--- description: globs: alwaysApply: true --- # Agent Instructions If you create a new file(s), pleas run the following command afterwards to update the project documentation.
If you create a new folder(s), pleas run the following command afterwards to update the project documentation.
~/.scripts/update_structure_folder.sh
注：这里的 alwaysApply 设置为 true，每次请求都会判断是否需要更新项目结构。
