Creating an isolated git worktree involves generating a new branch in a separate workspace directory. The process automatically ensures the directory is git-ignored, copies minimal configuration, runs language-specific setup, and validates tests.

You need a git worktree when starting a new feature or experimental branch that requires sandboxed development. It provides separate workspace and branch isolation within the same repository without manual branch switching.

Yes, git worktree setup automatically verifies and updates the .gitignore file. It confirms the designated worktree directory is git-ignored and adds it to .gitignore if necessary to ensure the workspace remains clean.

The best way to verify tests pass is through automated worktree creation. After setting up the worktree and copying minimal configuration, the process automatically runs language-specific setup commands and validates that tests pass before proceeding.

Yes, you can use an existing folder for your git worktree directory. The setup process determines the appropriate directory by checking configuration, identifying existing folders, or prompting for user input to ensure proper isolation.

You should avoid manual branch switching for experimental features because worktrees provide isolated environments within the same repository. This sandboxed development approach ensures your main workspace remains clean while testing new tasks.
