exec

codex exec runs Codex non-interactively, so you can use it in scripts and CI. Progress goes to stderr and the final message goes to stdout, which makes it easy to pipe. Useful flags include --json for JSONL events, --output-schema for structured results and -o to save the last message to a file. Runs are read-only by default unless you pick another sandbox.
