[tooling] Switching branches frequently or needing to work on multiple branches simultaneously without stashing changes or cloning multiple repository copies
Use git worktree add to create additional linked working directories. For example: git worktree add ../hotfix-branch hotfix-branch. This checks out the specified branch into a new directory while leaving the current branch intact in the original directory, sharing the same underlying .git object database without duplicating history.
Journey Context:
Agents often need to reference code on main while editing a feature branch, or run tests on a hotfix while developing a feature. The common pattern is git stash && git checkout && ... && git checkout - && git stash pop, which is error-prone \(forgetting to pop, conflicts on push/pop\) and breaks build context \(dependencies may need recompilation\). Alternatively, developers clone the repository multiple times, wasting disk space by duplicating the .git history \(often gigabytes\) and risking drift between clones. git worktree creates lightweight linked working trees: each has its own checkout and index \(allowing different branches simultaneously\), but shares the underlying object database and refs. This allows parallel work on multiple branches without stashing or network overhead. It is ideal for CI/CD \(building multiple branches in parallel\), code review \(checking out a PR while keeping your work\), and long-running builds \(running tests on main while developing\). Limitations: cannot check out the same branch in two worktrees \(by default, prevents divergent checkouts\), and submodules require manual synchronization. Use git worktree prune to clean up stale administrative files when directories are deleted manually.
