Git Worktree Manager

This skill provides a unified interface for managing Git worktrees across your development workflow. Whether you're reviewing PRs in isolation or working on features in parallel, this skill handles all the complexity.

What This Skill Does

Create worktrees from main branch with clear branch names
List worktrees with current status
Switch between worktrees for parallel work
Clean up completed worktrees automatically
Interactive confirmations at each step
Automatic .gitignore management for worktree directory
Automatic .env file copying from main repo to new worktrees

CRITICAL: Always Use the Manager Script

NEVER call git worktree add directly. Always use the worktree-manager.sh script.

The script handles critical setup that raw git commands don't:

Copies .env, .env.local, .env.test, etc. from main repo
Ensures .worktrees is in .gitignore
Creates consistent directory structure

# ✅ CORRECT - Always use the script
bash ${CLAUDE_PLUGIN_ROOT}/skills/git-worktree/scripts/worktree-manager.sh create feature-name

# ❌ WRONG - Never do this directly
git worktree add .worktrees/feature-name -b feature-name main

When to Use This Skill

Use this skill in these scenarios:

Code Review (/workflows:review): If NOT already on the target branch (PR branch or requested branch), offer worktree for isolated review
Feature Work (/workflows:work): Always ask if user wants parallel worktree or live branch work
Parallel Development: When working on multiple features simultaneously
Cleanup: After completing work in a worktree
