Claude Code Worktrees: How to Run Parallel Builds Without Merge Conflicts

The Problem Nobody Talks About You've set up Claude Code agents. Multiple instances, running in parallel, executing different parts of a build. Smart setup. Then the first merge conflict hits. Agent A was halfway through a feature. Agent B was refactoring the same file. Neither knew. Both checkpointed. Your main branch is now a crime scene. Git worktrees fix this. They're not a new feature — they've been in Git since 2015. But most Claude Code operators aren't using them, and it shows. This is the pattern that makes parallel agent builds actually work. What Git Worktrees Actually Are One repository, multiple working directories, each on its own branch. git worktree add ../my-repo-feature-a feature-branch-a git worktree add ../my-repo-feature-b feature-branch-b git worktree list Each worktree has: Its own filesystem path Its own branch (checked out exclusively — can't share with another worktree) Its own working tree (uncommitted changes are isolated) The same .git object store (no dupl
