AI Agents Need Their Own Desk, and Git Worktrees Give Them One

AI agents and developers often conflict when modifying code in the same working directory simultaneously. Git worktrees provide a solution by creating separate, isolated directories that point to the same repository but are locked to different branches. This allows an agent to perform a long-running task on one branch while a developer works on another without interference or needing to switch contexts. Worktrees enable parallel work across different branches, not multiple agents on the same branch, which requires task decomposition first. The rise of agentic AI for coding has made this previously niche Git feature a critical part of modern development workflows.
