Parallel Claude Code agents: why Git worktrees miss semantic conflicts

Running several Claude Code agents at once is far more manageable when each one gets its own Git worktree on a separate branch, which prevents them from overwriting each other's files. However, worktrees do not stop agents from producing plans that contradict each other, since Git merges text rather than intent and can combine such changes cleanly. These so-called semantic conflicts, such as a renamed function still being called elsewhere or two agents building the same feature twice, go unreported by Git. The article notes that worktrees also leave gitignored dependencies, ports, databases and branch checkouts unisolated, so each agent needs its own install and a distinct branch. It recommends assigning one integrator to merge branches and running real checks on the combined result rather than on each branch separately.
