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。
