Using Git Worktrees

Creates isolated Git workspaces so you can work on multiple branches without constant switching or stashing. It follows a smart priority system: checks for existing worktree directories, consults CLAUDE.md for preferences, then asks if needed. The real value is in the safety checks. It verifies project-local directories are gitignored before creating anything, auto-runs your project setup (npm install, cargo build, whatever), and confirms tests pass before you start coding. This prevents the classic mistake of accidentally committing worktree contents or building on a broken baseline. Pairs with brainstorming for implementation phases and has a matching cleanup skill for when you're done.
