Git Worktrees (experimental)

When working on multiple tasks at once, you can use Git worktrees to give each Gemini session its own copy of the codebase. Git worktrees create separate working directories that each have their own files and branch while sharing the same repository history. This prevents changes in one session from colliding with another.

Learn more about session management.

Learn more in the official Git worktree documentation.

How to enable Git worktrees

Git worktrees are an experimental feature. You must enable them in your settings using the /settings command or by manually editing your settings.json file.

Use the /settings command.
Search for and set Enable Git Worktrees to true.

Alternatively, add the following to your settings.json:

{
  "experimental": {
    "worktrees": true
  }
}

How to use Git worktrees

Use the --worktree (-w) flag to create an isolated worktree and start Gemini CLI in it.

Start with a specific name: The value you pass becomes both the directory name (within .gemini/worktrees/) and the branch name.
Terminal window
```
gemini --worktree feature-search
```
Start with a random name: If you omit the name, Gemini generates a random one automatically (for example, worktree-a1b2c3d4).
Terminal window
```
gemini --worktree
```

How to exit a Git worktree session

When you exit a worktree session (using /quit or Ctrl+C), Gemini leaves the worktree intact so your work is not lost. This includes your uncommitted changes (modified files, staged changes, or untracked files) and any new commits you have made.

Gemini prioritizes a fast and safe exit: it does not automatically delete your worktree or branch. You are responsible for cleaning up your worktrees manually once you are finished with them.

When you exit, Gemini displays instructions on how to resume your work or how to manually remove the worktree if you no longer need it.

Resuming work in a Git worktree

To resume a session in a worktree, navigate to the worktree directory and start Gemini CLI with the --resume flag and the session ID:

cd .gemini/worktrees/feature-search
gemini --resume <session_id>

Managing Git worktrees manually

For more control over worktree location and branch configuration, or to clean up a preserved worktree, you can use Git directly:

Clean up a preserved Git worktree:

git worktree remove .gemini/worktrees/feature-search --force
git branch -D worktree-feature-search

Create a Git worktree manually:

git worktree add ../project-feature-search -b feature-search
cd ../project-feature-search && gemini
