cwt — Provider (Claude, Codex, or Pi) Worktree Manager

A terminal UI for running parallel provider (Claude, Codex, or Pi) sessions in isolated git worktrees. Built in Rust, it uses a local terminal multiplexer for interactive session management, preferring zellij when available and falling back to tmux.

The worktree is the first-class primitive — sessions attach to worktrees, not the other way around.

Worktree (unit of work)
  |-- Branch (auto-created or user-specified)
  |-- Session (provider instance, 0 or 1 active)
  |-- Lifecycle: ephemeral | permanent
  |-- State: idle | running | waiting | done | shipping

Why cwt?

When using a provider (Claude, Codex, or Pi) on a real codebase, you often want to run multiple tasks in parallel — fix a bug, add a feature, write tests — without them stepping on each other. Git worktrees give you cheap, isolated copies of your repo. cwt manages the lifecycle of those worktrees and the provider sessions inside them, all from a single TUI.

Spin up a worktree in seconds — auto-named, auto-branched, ready to go
Never lose work — every deletion saves a .patch snapshot first
Stay organized — ephemeral worktrees auto-clean; permanent ones stick around
See everything at once — two-panel TUI with live session status, diff stats, and transcript previews
Scale up — dispatch tasks in bulk, import GitHub issues, broadcast prompts across sessions

Requirements

git (with worktree support)
zellij or tmux (interactive mode needs one local terminal multiplexer; zellij is preferred when both are installed)
A provider CLI (claude, codex, or pi)

Optional:

gh (GitHub CLI) — for PR creation and CI status
podman or docker — for per-worktree containers
ssh — for remote worktrees

Installation

Prebuilt binaries with cargo-binstall

cargo binstall cwt

cargo-binstall downloads the prebuilt release archive when one is available for your target. Install either zellij or tmux separately and make sure it is on your PATH.

Cargo (from crates.io)

cargo install cwt

cargo install does not install a terminal multiplexer for you. Install zellij or tmux separately and make sure it is on your PATH before running cwt.

Nix (recommended)

cwt provides a Nix flake with builds for Linux and macOS (x86_64 and aarch64). The Nix package includes tmux and git as runtime dependencies and wraps the binary so they are always on PATH. If zellij is also available in your environment, cwt will prefer it automatically for local interactive sessions.

# Run without installing
nix run github:0dragosh/cwt

# Install to your profile
nix profile install github:0dragosh/cwt

Add to a flake-based NixOS or home-manager configuration:

# flake.nix
{
  inputs.cwt.url = "github:0dragosh/cwt";

  # Option 1: use the overlay
  nixpkgs.overlays = [ cwt.overlays.default ];
  # then add pkgs.cwt to your packages

  # Option 2: reference the package directly
  environment.systemPackages = [ cwt.packages.${system}.default ];

  # Option 3: home-manager module (generates ~/.config/cwt/config.toml)
  imports = [ cwt.homeManagerModules.default ];
  programs.cwt = {
    enable = true;
    settings.session.default_permission = "elevated";
  };
}

See docs/nix.md for full home-manager module documentation.

From source

git clone https://github.com/0dragosh/cwt.git
cd cwt
cargo build --release
# Binary at target/release/cwt — add it to your PATH

Make sure git is on your PATH, and make sure zellij or tmux is installed and on your PATH. cwt cannot run its interactive workflows without one of them.

Quick Start

Interactive mode needs a local terminal multiplexer. If you launch cwt from a regular shell, it will bootstrap into a zellij session when zellij is installed, and otherwise fall back to tmux.

# 1. Navigate to any git repo
cd ~/my-project

# 2. Launch the TUI (cwt will bootstrap into zellij or tmux if needed)
cwt

# 3. Press 'n' to create a worktree (Enter for auto-generated name)
# 4. Press 's' to launch a provider session in it
# 5. Press 'Tab' to switch between the worktree list and inspector panels

Or use CLI commands directly:

cwt create my-feature --base main     # Create a worktree
cwt list                               # List all worktrees
cwt delete my-feature                  # Delete (saves a snapshot first)

# Dispatch parallel tasks — one worktree + session per task
cwt dispatch "implement auth" "add tests" "update docs"

# Import GitHub issues as worktrees
cwt import --github --limit 5

# Multi-repo mode
cwt add-repo ~/code/project-a
cwt add-repo ~/code/project-b
cwt forest                             # Launch forest TUI
cwt status                             # CLI summary across repos

Features

Worktree Management

Create with auto-generated slug names or explicit names, from any base branch
Two-tier lifecycle: ephemeral (auto-GC'd) and permanent (never auto-deleted)
Promote ephemeral worktrees to permanent with a single keypress
Snapshots: full diff saved as .patch before every deletion
Restore previously deleted worktrees from their snapshots
Garbage collection: prune old ephemeral worktrees, skipping those with running sessions, uncommitted changes, or unpushed commits
Setup scripts: automatically run a script (e.g., npm install) after worktree creation

TUI Interface

Two-panel layout: worktree list (grouped by lifecycle) + inspector (details, diff stat, session info)
Fuzzy filter: / to search/filter worktrees by name
Help overlay: ? for a full keybinding reference
Mouse support: click to select, scroll to navigate
Status bar: notification badges for waiting/done sessions

Terminal Multiplexer Support

Session Providers

cwt supports three provider options: claude, codex, and pi
You can set the default in config with session.provider = "claude", "codex", or "pi"
You can change the active provider at runtime by pressing o in the TUI
Press O to persist the currently selected provider as the default
Local interactive mode prefers zellij and falls back to tmux
Launching cwt outside a multiplexer auto-attaches to a cwt session in the preferred backend
In zellij, provider sessions and shells open in named tabs; in tmux, they open in panes/windows
Launch the active provider in the active multiplexer attached to any worktree
Resume previous sessions using the active provider's resume flow (--resume for Claude, resume <id> for Codex, --session <id> for Pi)
Focus an existing session tab/pane with a single keypress
Open shell in any worktree directory via the active multiplexer
Sessions survive TUI exit — closing cwt does not kill running sessions
Remote sessions still use tmux on the remote host today

Handoff

Bidirectional patch transfer between your main working directory and any worktree
Direction picker: worktree-to-local or local-to-worktree
Diff preview before applying
Gitignore gap warnings for untracked files that won't transfer

Hooks (Real-Time Provider Integration)

cwt provider support includes pi, but hook automation is still Claude-only in this phase
Unix domain socket listener for sub-second event delivery
Worktrees created by Claude outside cwt appear in the list within one second
cwt hooks install patches .claude/settings.json and writes hook scripts to .cwt/hooks/
Pi and Codex sessions do not currently get hook installation or real-time worktree import support

Forest Mode (Multi-Repo)

Register multiple repos with cwt add-repo <path>
Three-panel TUI: repos | worktrees | inspector
Aggregate session counts across all repos
cwt status for a one-line CLI summary

Agent Orchestration

Dispatch multiple tasks in parallel: cwt dispatch "task 1" "task 2" ...
Import issues from GitHub or Linear — creates worktrees and sessions per issue
Broadcast a prompt to all running sessions simultaneously

Ship Pipeline

Create PR from a worktree with auto-generated body from session transcript
CI status tracking: pass/fail/pending via gh run list
Ship it: one-keypress macro to push, create PR, and mark as shipping

Per-Worktree Containers

Podman or Docker support (prefers Podman for rootless compatibility)
Auto-detect Containerfile, Dockerfile, or .devcontainer/devcontainer.json
Port management: auto-assign non-conflicting ports per worktree

Permission Levels

cwt supports three permission tiers for provider sessions, giving you fine-grained control over how much autonomy the provider gets:

Level	Badge	Behavior
Normal	`N` (gray)	Plain provider command — asks for permission on each tool use (default)
Elevated	`E` (yellow)	Uses provider-specific elevated behavior; for Claude this injects sandbox settings into `.claude/settings.local.json`
Elevated Unsandboxed	`U!` (red)	Uses provider-specific unsandboxed behavior or configured extra args

Press m to cycle through modes at runtime
Press M to save the current mode as the default in your config
The active level is shown as a badge in the top bar
Claude worktrees get their own .claude/settings.local.json, so there are no concurrency conflicts between Claude sessions

Provider-specific mode behavior:

Claude: Elevated injects sandbox settings; Unsandboxed uses --dangerously-skip-permissions.
Codex: Unsandboxed uses --full-auto; Elevated Unsandboxed uses --dangerously-bypass-approvals-and-sandbox.
Pi: cwt passes only the configured session.permissions.<level>.extra_args; no Claude settings injection or Codex-specific flags are applied.

The elevated (sandboxed) provider mode writes these settings before launch:

{
  "permissions": { "allow": [], "deny": [] },
  "sandbox": {
    "enabled": true,
    "autoAllowBashIfSandboxed": true,
    "allowUnsandboxedCommands": false
  }
}

Starship prompt integration

cwt prompt prints the current managed worktree name when your shell is inside that worktree directory, and prints nothing otherwise. This makes it easy to surface worktree context in starship (similar to worktrunk):

[custom.cwt]
command = "cwt prompt"
when = "cwt prompt | grep -q ."
format = "[$output]($style) "
style = "bold purple"

Configuration

cwt reads configuration from .cwt/config.toml (per-project) and ~/.config/cwt/config.toml (global). Forest mode uses ~/.config/cwt/forest.toml.

[worktree]
dir = ".claude/worktrees"        # worktree root (relative to repo root)
max_ephemeral = 15               # GC threshold
auto_name = true                 # generate slug names when no name given

[setup]
script = ""                      # path to setup script (relative to repo root)
timeout_secs = 120               # setup script timeout

[session]
auto_launch = true               # launch session provider on worktree create
provider = "claude"              # "claude" | "codex" | "pi"
command = ""                     # optional command override (defaults to provider binary)
provider_args = []               # extra args for provider invocation
default_permission = "normal"    # "normal", "elevated", or "elevated_unsandboxed"

# Permission-level overrides (optional — sensible defaults built in)
# [session.permissions.normal]
# extra_args = []
#
# [session.permissions.elevated]
# extra_args = []
# [session.permissions.elevated.settings_override.sandbox]
# enabled = true
# autoAllowBashIfSandboxed = true
#
# [session.permissions.elevated_unsandboxed]
# extra_args = ["--dangerously-skip-permissions"]

[handoff]
method = "patch"                 # "patch" or "cherry-pick"
warn_gitignore = true            # warn about .gitignore gaps

[ui]
theme = "default"                # color theme
show_diff_stat = true            # show file change counts in list

[container]
enabled = false                  # enable container support
runtime = "auto"                 # "podman", "docker", or "auto"
auto_ports = true                # auto-assign ports per worktree

# Remote hosts (one [[remote]] block per host)
[[remote]]
name = "build-server"
host = "build.example.com"
user = "dev"
worktree_dir = "/data/worktrees"

Troubleshooting

cwt says "zellij or tmux is required" Install either zellij or tmux first, then run cwt again. When both are installed locally, cwt prefers zellij; otherwise it falls back to tmux.

Worktrees don't appear after a provider creates them Run cwt hooks install to set up the real-time hook integration. Without hooks, cwt discovers worktrees on periodic refresh (every few seconds). Hook-based import is currently Claude-only.

gh commands fail (PR creation, CI status) Make sure the GitHub CLI is installed and authenticated (gh auth login).

Sessions show "idle" even though the provider is running cwt detects session status by parsing provider session transcripts. Claude/Codex use ~/.claude/projects/; Pi uses ~/.pi/agent/sessions/. If the path hash doesn't match, status won't update. Restarting cwt re-scans the project directory.

GC skipped a worktree I expected it to prune GC never prunes worktrees with running sessions, uncommitted changes, or unpushed commits. Check cwt list for details.
