Could you build this?
No Implementing native copy-on-write Git worktrees requires deep low-level operating system and filesystem knowledge to leverage kernel-level reflink and clone primitives.
What it would actually take: The core tool must be built in a systems programming language like Rust or C that directly interacts with low-level platform APIs (such as Linux FICLONE ioctls or macOS clonefile). It requires intimate knowledge of Git's index format, worktree pointers, and inode deduplication semantics to avoid file corruption when running concurrent agents. A vibe-coder lacks the systems-level debugging skills needed to handle platform-specific filesystem drivers and transactional checkout consistency.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
