Why Your Setup Script Must Support Git Worktrees for Parallel Development

I argue that modern setup scripts must support Git worktrees to enable safe parallel development, especially with coding agents. Instead of running separate Docker stacks for every branch, I advocate sharing infrastructure while isolating ports, databases, and state. This approach ensures that multiple worktrees can run simultaneously without conflicts, turning a simple checkout into a fully functional environment with one command.

Running a complete Docker stack for every worktree is the simplest mental model and often the wrong default.
