Codex CLI starts a persistent, self-updating daemon by default

github.com 8 min read Editor score 7/10

A Codex CLI issue reports that opening an interactive session launches a managed daemon that persists after the window closes and copies a platform package of about 374 MB. Agent developers should check background-process behavior, update paths and resource use in their own tools.

What: A Codex CLI 0.157.0 issue report says opening an interactive session starts a persistent app-server daemon by default.
How: The reported daemon copies the platform package and launches an updater that checks after five minutes, then hourly, and restarts the backend.
Why it matters: Daemon persistence can decouple backend versions from package-managed CLI versions and retain a session's proxy environment.

The CLI starts a managed daemon, whose updater can restart the backend. Sketched from the article's own text.
