Git Worktrees Offer a Clean Fix for Running Multiple Coding Agents in Parallel

Developer Andrew Pyle describes how running two AI coding agents simultaneously on the same project caused conflicts when both edited files in a shared directory. His initial instinct to coordinate agents through locks or queues proved flawed, as adding more agents only multiplied the coordination complexity. The cleaner solution, he argues, is eliminating shared state entirely rather than managing access to it. Git's built-in worktree feature allows each agent to operate in its own isolated checkout on a separate branch, all sharing one underlying object store without duplicating full repository history. This approach keeps setup costs low, scales easily to many parallel agents, and simplifies merging once each agent's work is complete.
