Git Worktrees Fail to Provide Isolation for Coding Agents

Recent analysis shows that Git worktrees do not isolate coding agents effectively. Worktrees share the same repository metadata as the main working directory. This shared state allows agents to interfere with each other’s environment. The lack of isolation can lead to unintended side effects during automated tasks. Developers seeking sandboxed execution may need alternative solutions. Cloning full repositories remains a more reliable isolation method. The findings challenge common assumptions about worktree safety. Teams are advised to evaluate their tooling choices for agent isolation.
