About
The codex-sandbox skill enables developers to execute code in Codex's fully isolated sandbox environment with network disabled and Seatbelt/Docker isolation. It's designed for safe experimentation with untrusted or risky code while maintaining access to local filesystem operations. Developers should follow its mandatory library-first protocol to reuse existing code patterns before building new solutions.
