Git Worktree: The Feature I Knew About but Never Tried Until I Had To

Git worktree, a Git feature enabling parallel development across multiple branches simultaneously, remained largely unused by a developer who relied on a single-branch workflow until forced to adopt it. The developer previously managed tasks sequentially with one branch and one agent at a time, occasionally expanding to three agents for separate functions like implementation, research, and frontend work. The shift to git worktree occurred only when the limitations of the single-branch approach became unavoidable.

I’d written about git worktree before https://blog.yushi91.com/blog/git-worktrees-parallel-development-ai/ , and I’d heard it come up in discussions about parallel workflows plenty of times. Every time I nodded and thought “that sounds useful” and then went back to my single-branch life. My normal workflow was simple: one branch, one agent, one task at a time. Sometimes I’d open a second agent for a code review or quick QA check, but that was it. The most I ever pushed it was three agents at once: one implementing, one doing research with Gemini, and one handling frontend. Even then, they barely touched the same files, and the work was still mostly sequential.
