The Cheapest Way to Sandbox an AI Coding Agent on Windows

Windows drive letters offer a simple, low-overhead sandbox for AI agents to prevent accidental file deletion. By mapping a local folder or WebDAV workspace via subst.scsoi.com or drive.scsoi.com to a specific letter, agents operate within an isolated filesystem root. This method avoids the complexity of Docker or VMs and requires no subscriptions. While not replacing network or dependency isolation, it ensures agents cannot access files outside their designated drive, providing an efficient OS-level isolation solution.
