Week 11: Git Worktree

This is a very cool command in Git.

Nowadays, because of vibe coding, I may use several AIs to work on different features. Sometimes I also need to checkout other branches to check code changes.

Before, I usually solved this by:

• cloning the same project into different folders, or
• committing/stashing my current work before switching branches.

But with git worktree, things become much easier. 🚀

Inside one project repository, you can create multiple folders for different branches.

Expected Folder Structure

For example, your folder structure can look like this:

/project
/project/.git
/project/main
/project/feature-1

Step 1 — Clone as a Bare Repository

First create your project folder, then clone the repository as a bare repo into .git.

git clone --bare ${project} .git

Step 2 — Create the Main Worktree

Create the main folder and add a worktree for the main branch.

git worktree add ./main main

This folder will be used to pull and update the main branch.

Step 3 — Create Feature Branch Worktrees

When you want to work on a new feature, create another folder and add a worktree.

From inside main (or any branch you want to branch from):

git worktree add ../feature-1 feature-1

Now you can work on multiple branches at the same time, each in its own folder.

Step 4 — Update Submodules (If Needed)

If your project uses submodules like mine, remember to update them.

git submodule update --init --recursive

Why This Is Useful

With git worktree you can:

• work on multiple branches at the same time
• avoid cloning the repo many times
• quickly switch between features
• let different AI agents work in different folders 🤖

For AI-assisted development, this workflow is extremely convenient.
