Codex sandbox preflight
When to use
- Start of a new Codex session (default).
- You see sandbox-ish errors like
PermissionError: [Errno 1] Operation not permitted,seccomp, or unexpected “Permission denied” when paths look writable. - You need to know if network is disabled in the tool sandbox before attempting auth, installs,
git push, etc.
Workflow
- Run the preflight helper:
scripts/codex-sandbox-preflight.sh
- If you’re in a normal shell and want to see what happens when network is enabled inside the sandbox:
scripts/codex-sandbox-preflight.sh --with-network
