This manages git worktrees so you can work on multiple branches simultaneously without the usual context switching hassle. Instead of stashing changes or cloning repos multiple times, you spin up separate working directories from the same git repository. Useful when you're jumping between a feature branch and a hotfix, or need to compare implementations side by side. The skill handles the worktree commands and keeps track of what's where. It's one of those git features that sounds niche until you try it, then you wonder why you ever dealt with constant branch switching.
