git-worktree（Git 工作树）

Git Worktree Manager

Overview

This skill provides a unified interface for managing git worktrees, enabling isolated parallel development. Worktrees allow you to have multiple branches checked out simultaneously in separate directories.

Key features:

• Automatic .env file copying from main repo to new worktrees
• Unified storage in .worktrees/ directory
• Cleanup of merged and stale worktrees

When to Use This Skill

• Creating isolated environments for feature development
• Working on multiple branches simultaneously
• Reviewing PRs without stashing current work
• Cleaning up completed feature branches

Critical: Always Use the Manager Script

Always use the worktree-manager.sh script rather than raw git worktree commands. The script handles:

• Automatic .env file copying to new worktrees
• Consistent storage in .worktrees/ directory
• Proper .gitignore management

Core Commands

All operations use the unified worktree-manager.sh script:

bash scripts/worktree-manager.sh <command> [options]

Create Worktree

worktree-manager.sh create <branch-name> [source-branch]

Creates a new worktree in .worktrees/<branch-name>. If the branch exists, it checks it out. If not, creates a new branch from the source (defaults to main/master).

List Worktrees

worktree-manager.sh list

Shows all worktrees with their branch, commit, and status (clean/dirty/missing).

Switch Worktree

worktree-manager.sh switch <branch-name|path>

Provides information for switching to a worktree by branch name or path.

Cleanup Worktrees

worktree-manager.sh cleanup [--force]

Identifies and removes:

• Worktrees with merged branches
• Worktrees with deleted remote branches
• Missing worktree directories

Use --force to skip confirmation prompt.

Copy Environment Files

worktree-manager.sh copy-env [worktree-path|branch-name]

Copies .env* files (excluding .env.example) from the main repo to a worktree. Useful for:

• Adding env files to existing worktrees created before this feature
• Refreshing env files after main repo changes

If run inside a worktree without arguments, copies to current location.

Storage

Worktrees are stored in .worktrees/ within the repository root. This directory is automatically added to .gitignore.

Example Workflow

# Start new feature
worktree-manager.sh create feature-auth

# Work in the new worktree
cd .worktrees/feature-auth

# List all worktrees
worktree-manager.sh list

# When done, clean up
worktree-manager.sh cleanup

Troubleshooting

Missing.env files in existing worktrees

If you have existing worktrees created before the automatic env copying feature:

bash scripts/worktree-manager.sh copy-env feature-branch

Or from within the worktree directory:

bash scripts/worktree-manager.sh copy-env
