Brief

Codex’s compaction behavior is the focus of this 2026-03-31 post: Romain Huet highlights that Codex CLI offers a manual /compact command, but says users prefer Codex’s automatic compaction and often forget context-window constraints altogether.

You can use /compact in Codex CLI, but people really like the auto compaction in Codex and tend to forget about the context window. Would love your feedback!
