wt

Part of @sahil87's open source toolkit — see all projects there.

A small CLI that wraps git worktree with opinionated defaults: worktrees are created as siblings of the main repo (<repo>.worktrees/<name>/), names are memorable random adjective-noun pairs, and a shell wrapper makes cd-into-worktree from a menu actually work. Designed for the parallel-edit workflow where each branch (or each AI session) gets its own checkout.

Why wt?

• Sibling layout, not clutter — worktrees go in <repo>.worktrees/<name>/, never inside the main repo.
• Memorable names — random adjective-noun pairs (lively-otter, bold-fox) instead of feature-1, feature-2.
• Real cd from a menu — the shell wrapper lets wt open actually change your shell's directory (something a plain binary can't do).
• Per-worktree init — each new worktree runs an init script (default fab sync, override via WORKTREE_INIT_SCRIPT) so it's ready to use immediately.

Install

Homebrew (preferred):

brew install sahil87/tap/wt

Manual (requires Go and just):

git clone https://github.com/sahil87/wt
cd wt
just local-install   # builds bin/wt and copies to ~/.local/bin/wt

For the "Open here" menu option to actually cd your current shell, add the wrapper to your shell profile:

eval "$(wt shell-init)"

💡 Have other sahil87 tools? shll shell-install handles all of their shell integrations and autocompletions at once.

Usage

A typical first session:

$ wt create
Created: ../wt.worktrees/lively-otter
  Branch: lively-otter (from main)

$ wt list
Worktrees for: wt
Location: /Users/you/code/wt.worktrees

  Name          Branch         Path
* (main)        main           wt/
  lively-otter  lively-otter   wt.worktrees/lively-otter/

$ wt open lively-otter        # menu → "Open here" cd's your shell
$ wt delete lively-otter      # removes worktree (and optionally the branch)

Command reference

Command	Summary
wt create [branch]	Create a worktree (random name + new branch, or named branch). Key flags: --base <ref>, --reuse, --worktree-name, --non-interactive.
wt list	List all worktrees with name, branch, and path. Add --status for dirty/unpushed indicators; --path and --json for scripting.
wt open [name|path]	Open a worktree in a detected app (editor, terminal, file manager). --app to skip the menu.
wt delete [names...]	Delete one or more worktrees with optional branch cleanup.
wt init	Run the worktree init script (default fab sync, override via WORKTREE_INIT_SCRIPT).
wt shell-init	Print a shell wrapper function for eval in your shell profile.

Run wt <command> --help for inline flag details, or see docs/specs/cli-surface.md for the full per-flag reference and exit codes.

wt create --base — branch start-point

--base <ref> controls the start-point when wt creates a new branch (maps to git worktree add -b <branch> <path> <start-point>). Behavior depends on whether the branch already exists:

Scenario	--base	Behavior
New branch (doesn't exist locally or remotely)	provided	Branch created from --base ref
New branch	omitted	Branch created from HEAD (default)
Existing local branch	provided	Warning: --base ignored: branch already exists locally
Existing remote branch	provided	Warning: --base ignored: fetching existing remote branch
Exploratory (no branch arg)	provided	Exploratory branch created from --base ref
Exploratory	omitted	Branch created from current HEAD (default)
With --reuse (worktree exists)	provided	--reuse takes precedence; --base has no effect
Invalid ref	provided	Error exit; no worktree or branch created

The ref is validated via git rev-parse --verify before worktree creation, so invalid refs produce a clear error rather than a partial failure.

wt open — context-aware launcher

wt open is the one command worth knowing in detail. It's the canonical directory launcher in the toolkit (hop delegates to it too), and what it does depends on where you run it from and what you pass it:

Where you are	What you type	What happens
Inside a worktree	wt open	Opens the current worktree in your editor / terminal / file manager.
In the main repo	wt open	Shows a worktree-selection menu (most recently modified is highlighted).
In a non-git directory	wt open	Opens the current directory (equivalent to wt open .).
Anywhere	wt open lively-otter	Resolves the name against this repo's worktrees and opens it. (Requires a git repo.)
Anywhere	wt open /tmp/notes	Opens that directory literally — git context doesn't matter.
Anywhere	wt open --app cursor	Skips the menu and opens in the named app.

The menu lists the apps wt detected on your machine (editors, terminals, file managers) plus an "Open here" option that cds your current shell into the target — that one needs the shell wrapper (see Gotchas).

Running wt open from the main repo, with two worktrees on disk:

$ wt open
Select worktree to open:
  1) lively-otter (feature/spinner) (default)
  2) bold-fox    (fix/race-condition)
  0) Cancel

Choice [1]: 1
Open in:
  1) Open here
  2) VSCode (default)
  3) Cursor
  4) Ghostty
  5) Terminal.app
  6) Finder
  7) Copy path
  0) Cancel

Choice [2]:

Pick 1 to cd your shell into the worktree, 2–6 to launch it in a detected app, or 7 to copy the absolute path to your clipboard.

Gotchas

• wt open can't cd without the shell wrapper. A child process can't change its parent shell's directory — that's a Unix constraint, not a wt bug. eval "$(wt shell-init)" installs a shell function that wraps the binary so the "Open here" menu option actually works.
• --base is ignored when the branch already exists (locally or on the remote) — wt checks out the existing branch instead and prints a warning. --reuse also takes precedence over --base.
• Worktrees survive cd into deleted directories. If you delete a worktree from outside (rm -rf), run git worktree prune in the main repo to clean up git's bookkeeping.
