How to Use Git Worktrees to Run Multiple AI Agents on the Same Repo

If you're running multiple AI coding agents on the same repository, you've probably hit this: Agent A edits src/auth.rs while Agent B is also editing src/auth.rs. One overwrites the other. Nobody notices until the tests fail - or worse, until production breaks. The fix is surprisingly simple, and it's been in git since 2015: worktrees. What Git Worktrees Are A git worktree is a separate working directory linked to the same repository. Each worktree has its own branch, its own staged changes, and its own files on disk - but they all share the same.git history.
