Codex CLI Reference

Session Continuation

# Resume a previous session
codex resume [session-id] "[prompt]" --sandbox read-only --ask-for-approval never 2>&1

Note: Session IDs are returned in Codex output.

Bash Execution Notes

Use dangerouslyDisableSandbox: true for Bash calls
Always append 2>&1 to capture all output
Use timeout of 300000ms (5 min) or longer for complex tasks

Safety Requirements

NEVER use these flags:

--dangerously-bypass-approvals-and-sandbox - FORBIDDEN
--sandbox danger-full-access - FORBIDDEN

Troubleshooting

Timeout: Complex analysis may take 5-10 minutes. Use longer timeout values.
