Git worktrees work by creating dedicated working directories linked to your repository, allowing you to isolate feature development. This mechanism prevents cross-branch contamination and ensures experiments do not pollute the main branch.

To create a git worktree for prototyping, run an automated isolation process that enforces safe directory selection and baseline checks. This ensures reliable isolation and prevents accidental commits to the main repository during experiments.

Yes, git worktree isolation prevents cross-branch contamination by using auto-verification and baseline checks. This ensures reliable isolation so parallel experiments cannot accidentally pollute your main repository or break existing builds.

You should use dedicated git worktrees to manage multiple feature branches without breaking builds. This worktree-management approach provides safe directory selection and baseline checks to keep experimental work safely isolated.

You should use git worktrees during feature development, planning, and prototyping when clean baselines and safe rollbacks are required. They are essential whenever parallel experiments risk contaminating your main repository or complicating rollbacks.
