git-wt — Git Worktree Manager

git-wt manages isolated git worktrees stored globally at ~/.git-wt/<repo>/<name>/. Worktrees live outside the repo — no .gitignore changes needed.

Prerequisites

git-wt must be installed and in PATH. Verify with git wt --version.

If not installed, ask the user to install it themselves.

Commands Reference

Create a worktree

git wt new                           # Auto-named (e.g., swift-jade)
git wt new my-feature                # Named
git wt new -b main hotfix            # Fork from specific branch
git wt new --copy-env experiment     # Copy .env* files into worktree
git wt new --copy-ai my-feature      # Copy AI configs, save sessions on rm
git wt new --no-branch scratch       # Detached HEAD (no branch created)

Check out an existing branch

git wt checkout feature/login           # Local branch → worktree
git wt checkout origin/fix/bug-42       # Remote → local tracking branch → worktree
git wt checkout fix/bug-42              # Auto-detects from remote
git wt checkout feature/login my-fix    # Custom worktree name
git wt checkout --copy-env feature/api  # Also copy .env files

Navigate to a worktree

cd $(git wt path <name>)             # Jump into worktree
git wt open <name>                   # Open in Cursor/VS Code/$EDITOR

List worktrees

git wt list                          # Worktrees for current repo (managed + external)
git wt list-all                      # Managed worktrees across ALL repos

External worktrees (created via git worktree add) appear with [external] tag.

Adopt an external worktree

git wt adopt my-hotfix               # Adopt by name from list
git wt adopt ../my-hotfix            # Adopt by path (name = basename)
git wt adopt /tmp/wt/fix fix-login   # Adopt with custom name

Moves an external worktree under ~/.git-wt/ management.

Find the main repo

git wt origin                        # Print main repo path (from any worktree)

Remove worktrees

git wt rm <name>                     # Remove managed worktree + delete its branch
git wt clean                         # Remove all managed worktrees for current repo

rm only works on managed worktrees (under ~/.git-wt/). For external worktrees, run git wt adopt first.

Key Details

• Storage: ~/.git-wt/<repo>/<name>/ — outside the repo, globally managed
• Branches: prefixed wt/ by default (e.g., wt/my-feature)
• Naming: auto-generates adjective-noun names if no name given
• rm: only works on managed worktrees — removes directory and deletes its branch
• adopt: moves an external worktree under ~/.git-wt/ so git-wt fully manages it
• External worktrees: list, path, open work with worktrees created outside git-wt
• checkout: checks out an existing branch (local or remote) into a managed worktree — does NOT create new branches
• --copy-env: copies .env* files from repo root into the new worktree directory (local filesystem only)
• --copy-ai: copies AI config files into worktree on create; archives session files back on rm (local filesystem only)
• origin: prints main repo path — works from any worktree or main repo itself

Environment Variables

• GIT_WT_HOME — Root directory for all worktrees (default: ~/.git-wt)
• GIT_WT_PREFIX — Branch name prefix (default: wt)
• GIT_WT_COPY_AI — Always copy AI configs on new, save sessions on rm (default: false)
• GIT_WT_AI_PROVIDERS — Space-separated AI providers to manage (default: claude)

When to Use

Use git wt new when:

• Working on a separate task that needs isolation from current work
• Running parallel agents that each need their own repo copy
• Experimenting without affecting the current branch
• Needing to quickly switch context between features

Use git wt new --copy-env when:

• The project has .env files needed for the dev server to start
• The worktree needs the same configuration as the main repo

Use git wt new --copy-ai when:

• Working with Claude Code or other AI tools in worktrees
• You want approved commands (.claude/settings.local.json) available immediately
• You want Claude sessions archived (not lost) when the worktree is removed

Use git wt checkout when:

• You need to work on an existing branch in an isolated worktree
• You want to check out a remote branch without manually creating a tracking branch
• You’re reviewing someone else’s PR branch in isolation

Use git wt adopt when:

• A worktree was created with git worktree add and you want git-wt to manage it
• You want the worktree moved to ~/.git-wt/ for consistent management

Shell Aliases

Optional aliases/git-wt.sh provides shorter commands. Source it in .bashrc/.zshrc:

Security

• All operations are local filesystem only — git-wt never makes network requests or sends data externally
• --copy-env copies .env* files between local directories on the same machine (repo root → worktree)
• --copy-ai copies AI config/session files between local directories on the same machine
• No credentials, tokens, or secrets leave the local filesystem
• Worktrees are stored under ~/.git-wt/ with standard filesystem permissions

Workflow: Parallel Agent Isolation

# Agent 1: create isolated worktree with AI config
git wt new --copy-env --copy-ai task-auth

# Agent 2: create another
git wt new --copy-env --copy-ai task-api

# Each agent works independently in their worktree
cd $(git wt path task-auth)

# When done — sessions archived, settings synced back
git wt rm task-auth
git wt rm task-api
