Claude Code Worktree: Run Multiple AI Tasks in Parallel

You open your terminal. Claude Code is halfway through building a new authentication module. Then Slack pings: there’s a production bug that needs fixing now.

What do you do? Stash your half-finished changes and hope you remember to pop them later? Force-commit a broken state just to switch branches? Tell your team to wait?

This is the fundamental constraint of single-directory development: one working directory can only hold one task at a time. Switching branches changes your files, but it doesn’t give you isolation. If two Claude Code sessions operate on the same directory, they will step on each other’s changes.
