## AI overview

OpenAI describes how the Codex engineering team built a Windows sandbox to constrain file access, network access, permissions, and descendant processes while running coding-agent commands. The article explains the safety trade-offs that motivated the work and contrasts Windows' available isolation primitives with sandboxing facilities on macOS and Linux.
