Parallel Development

Run 5+ Claude Code sessions simultaneously to maximize productivity.

Why Parallel Sessions?

Don't wait for Claude to finish one thing before starting another.

Benefits:

• Work on multiple features simultaneously
• Don't block on long-running tasks
• Experiment without affecting main work

Git Worktrees

Worktrees allow multiple working directories from a single repository.

Creating a Worktree

# Create worktree with new branch
git worktree add -b feature/auth ../project-auth main

# Create worktree with existing branch
git worktree add ../project-fix-123 fix/issue-123

Listing Worktrees

git worktree list

Removing Worktrees

git worktree remove ../project-auth
git worktree prune

Parallel Session Workflow

1. Identify Independent Tasks

Choose tasks that don't overlap in files.

2. Create Worktrees

git worktree add -b feature/auth ../project-auth main
git worktree add -b feature/ui ../project-ui main

3. Start Claude Sessions

Open separate terminals for each worktree:

cd ../project-auth && claude
cd ../project-ui && claude

4. Work Independently

Each session works on its task.

5. Merge Results

git checkout main
git merge feature/auth
git merge feature/ui

6. Clean Up

git worktree remove ../project-auth
git worktree remove ../project-ui

Best Practices

1. Independent tasks: Choose work with different file footprints
2. Focused sessions: One task per worktree
3. Regular syncs: Pull main into feature branches
4. Clean up: Remove worktrees when done
