git-worktree-setup

name	git-worktree-setup
description	Use PROACTIVELY when working on multiple branches simultaneously or creating parallel Claude Code sessions. Automates git worktree creation with prerequisite checking, development environment initialization, and safe cleanup. Supports single worktree, batch creation, and worktree removal. Not for non-git projects or branch management without worktrees.

Git Worktree Setup

Automates git worktree creation for parallel Claude Code sessions without conflicts.

When to Use

Trigger Phrases:

• "create a worktree for [branch-name]"
• "set up worktree for [feature]"
• "create worktrees for [branch1], [branch2]"
• "remove worktree [name]"
• "list my worktrees"

Use Cases:

• Working on multiple features simultaneously
• Parallel Claude Code sessions on different branches
• Code review while continuing development
• Emergency hotfixes without interrupting work

Quick Decision Matrix

Request	Mode	Action
"create worktree for X"	Single	Create one worktree
"set up worktrees for X, Y"	Batch	Create multiple
"remove worktree X"	Cleanup	Remove specific
"list worktrees"	List	Display status

Workflow Overview

Phase 0: Prerequisites (Mandatory)

# Verify git repo
git rev-parse --is-inside-work-tree

# Check uncommitted changes
git status --porcelain

# Get repo name
basename $(git rev-parse --show-toplevel)

Phase 1: Gather Information

• Branch name (required)
• New or existing branch
• Location (default: ../repo-branch)
• Setup dev environment

Phase 2: Create Worktree

# New branch
git worktree add ../project-feature -b feature

# Existing branch
git worktree add ../project-bugfix bugfix

Phase 3: Dev Environment Setup

• Detect package manager
• Run install
• Copy .env files

Phase 4: Next Steps

• Show worktree path
• Provide navigation commands
• List all worktrees

Quick Reference Commands

# Create with new branch
git worktree add ../project-branch -b branch-name

# Create from existing
git worktree add ../project-branch branch-name

# List all
git worktree list

# Remove worktree
git worktree remove ../project-branch

# Remove worktree and branch
git worktree remove ../project-branch
git branch -D branch-name

Package Manager Detection

Lock File	Manager
pnpm-lock.yaml	pnpm
yarn.lock	yarn
bun.lockb	bun
package-lock.json	npm

Common Issues

Issue	Cause	Fix
"invalid reference"	Branch doesn't exist	Use -b for new
"already exists"	Directory exists	Choose different location
"uncommitted changes"	Dirty working dir	Commit or stash

Safety Protocols

Before Creating:

• Verify git repository
• Check clean working directory
• Validate target directory available

Before Cleanup:

• Confirm user intent
• Check for uncommitted changes
• Warn about permanent branch deletion

Example Output

✓ Worktree created: /Users/connor/myapp-feature-auth
✓ Branch: feature-auth (new)
✓ Dependencies installed

Next steps:
  cd ../myapp-feature-auth
  claude

All worktrees:
- /path/to/main (main) ← current
- /path/to/worktree (feature-auth) ← new

Success Criteria

• Worktree in correct location
• Branch checked out properly
• Files visible in directory
• Dev environment ready
• Appears in git worktree list
• User can start Claude Code
