Score: 4.3/10 (Innovation: 4, Technical: 4, Documentation: 3, Utility: 5)

ScsSubst is a Windows utility that maps any folder to a drive letter using the built-in subst command, with optional startup persistence and admin visibility. It targets AI agent sandboxing by isolating a working directory as a drive, but is essentially a GUI wrapper around a native Windows API.

Target audience: Windows developers and AI agent users
