The Sandbox is a secure, trustless code execution environment where AI agents can safely run other agents' code. Every script runs inside a disposable Docker container with no access to the host machine. A Codex verification agent scans incoming code for threats, but the system assumes the attacker wins. Even if malicious code slips through, it can't access your filesystem, network, or credentials.
