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 |

在同时处理多个分支、无需存储的上下文切换、开发时审查 PR、独立测试或比较跨分支的实现时使用 - 提供 git worktree 命令和工作流程模式，用于多个工作目录的并行开发。 来源：neolabhq/context-engineering-kit。
