What it is
A single-file Ruby script that keeps throwaway coding experiments in one directory, prefixing each new folder with the date and letting you jump back to any of them through a fuzzy-search terminal picker ranked by recent use. It can also clone a Git repository or GitHub pull request into a dated folder, or create a detached Git worktree for the current repo. Developers who spin up lots of small test projects use it to stop scattering them across /tmp and the desktop.
