git:worktrees

Git worktrees enable checking out multiple branches simultaneously in separate directories, all sharing the same repository. Create a worktree instead of stashing changes or cloning separately.

Core principle: One worktree per active branch. Switch contexts by changing directories, not branches.

| Main worktree | Original working directory from git clone or git init | | Linked worktree | Additional directories created with git worktree add | | Shared .git | All worktrees share same Git object database (no duplication) | | Branch lock | Each branch can only be checked out in ONE worktree at a time |

在同時處理多個分支、無需儲存的上下文切換、開發時審查 PR、獨立測試或比較跨分支的實現時使用 - 提供 git worktree 命令和工作流程模式，用於多個工作目錄的平行開發。 來源：neolabhq/context-engineering-kit。
