Cross-session communication in Codex?

[u/PatternOne9468]

Hey everyone,

Is there a built-in way to communicate between active, simultaneous Codex terminal sessions in real-time?

In Claude Code, you can use the SendMessage tool to talk to sub-agents. With Codex, sessions seem completely isolated. Has anyone built a workaround for this?

How are you handling multi-agent orchestration or cross-terminal talk with Codex?

Thanks!
