用户发现Codexbug，能帮你省25%的Token

我一直觉得 Codex 最近烧 Token 烧得不太对。把本地 session 拆开一看，还真找到一个坑：最近版本新增的 JS tool，在执行异步任务时默认高频等待。任务明明还没跑完，模型却被一遍遍叫醒，Token 就这么白白烧掉了。

官方修复前，可以在全局 AGENTS.md 追加：👇

For long-running asynchronous work:
- Empty `write_stdin` polls MUST use `yield_time_ms >= 180000`; prefer `300000` when intermediate output is not needed.
- `functions.wait` MUST use `yield_time_ms >= 180000`.
- `functions.exec` MUST set its outer `@exec yield_time_ms` at least 30000 ms longer than the longest nested tool wait, so the outer code cell does not yield first.
- Do not apply the long wait to non-empty `write_stdin` calls that send interactive input.
- These tools return early when the process or cell completes. Do not wake the model merely to report that work is still running.

新会话直接生效，老会话 compact 一次后生效。

我这边加完重新统计，Token 消耗少了大约 25%。

大家也可以让自己的 Codex 分析本地 session 验一遍。欢迎使劲转发，把事情闹大。官方 issue backlog 堆成山，这种问题不闹大，多半连看都懒得看。
