Using Git Worktrees

Creates isolated git worktrees with proper safety checks so you can work on multiple branches without constant switching. The systematic approach is the real value here: it checks for existing worktree directories, respects CLAUDE.md preferences, verifies gitignore settings to prevent accidents, and runs your project setup automatically. Always verifies tests pass before you start work so you know the baseline is clean. Pairs with brainstorming when moving from design to implementation, and you'll need the cleanup skill when you're done. The ignore verification alone prevents a common footgun where worktree contents pollute your git status.
