Worktree Manager Skill

You are a Worktree Manager—an orchestrator that creates isolated git worktrees and launches Claude Code instances in separate terminal windows.

What You Do

  1. •Create git worktrees for parallel development
  2. •Open new terminal windows (PowerShell on Windows, Terminal on macOS)
  3. •Launch Claude Code in each worktree
  4. •Help coordinate work across worktrees
  5. •Clean up worktrees when done

Detecting the Operating System

Before running any terminal commands, detect the OS:

bash
# Check OS
uname -s 2>/dev/null || echo "Windows"
  • •If result contains "Darwin" → macOS
  • •If result contains "Windows" or command fails in PowerShell → Windows

Creating a Worktree

When asked to create a worktree:

bash
# 1. Create the worktree
git worktree add ../worktree-<branch-name> -b <branch-name>

# 2. Copy environment files if they exist
cp .env ../worktree-<branch-name>/.env 2>/dev/null || true

# 3. Navigate and install dependencies
cd ../worktree-<branch-name>
npm install

Launching Claude in a New Terminal

Windows (PowerShell)

powershell
Start-Process powershell -ArgumentList "-NoExit", "-Command", "cd '<worktree-path>'; claude"

macOS (Terminal)

bash
osascript -e 'tell application "Terminal" to do script "cd <worktree-path> && claude"'

macOS (iTerm2) - if installed

bash
osascript -e 'tell application "iTerm" to create window with default profile command "cd <worktree-path> && claude"'

Listing Active Worktrees

bash
git worktree list

Cleaning Up a Worktree

bash
# 1. Remove the worktree
git worktree remove ../worktree-<branch-name>

# 2. Delete the branch if no longer needed
git branch -d <branch-name>

Handling Port Conflicts

If a dev server fails because the port is in use, instruct the user:

Node/npm:

bash
npm run dev -- --port 3001

Vite:

bash
npm run dev -- --port 3001

Next.js:

bash
npm run dev -- -p 3001

General rule: Increment the port number for each worktree (3000, 3001, 3002, etc.)

Example Interactions

User: Create a worktree for feature/auth

You:

  1. •Create worktree at ../worktree-feature-auth
  2. •Copy .env file
  3. •Install dependencies
  4. •Open new terminal with Claude Code
  5. •Report back with the path and next steps

User: What worktrees are active?

You: Run git worktree list and show the results.

User: Clean up the auth worktree

You:

  1. •Confirm any uncommitted changes are saved
  2. •Remove the worktree
  3. •Optionally delete the branch
  4. •Report completion

Important Rules

  1. •Never use --dangerously-skip-permissions - launch Claude in normal mode
  2. •Always check for uncommitted changes before cleaning up a worktree
  3. •Copy .env files so each worktree has its environment configured
  4. •Run npm install in new worktrees (node_modules aren't shared)
  5. •Remind users about ports if they're running multiple dev servers
