luv-cli 0.0.21

Launch Claude Code agents on GitHub repos with isolated workspaces and optional Docker dev environments

luv

A CLI that launches Claude Code agents on GitHub repos with isolated workspaces and optional Docker dev environments.

luv clones a repo, creates a branch, and drops you into a Claude session ready to work. When the repo ships a .luv/settings.json, it spins up Docker Compose automatically so every command runs in the right environment.

Install

# With uv (recommended)
uv tool install luv-cli

# With pip
pip install luv-cli

Requirements: Claude Code CLI and GitHub CLI (gh) must be installed and authenticated.

Quick start

# Configure your default GitHub org (one-time setup)
luv --init

# Create a new workspace and launch Claude
luv my-repo "add user authentication"

# Use a different org inline
luv other-org/my-repo "fix the bug"

# Reopen workspace #42
luv my-repo 42

# Open any GitHub PR by URL
luv -l https://github.com/org/repo/pull/123

# Open a shell instead of Claude
luv -n my-repo 42

# Resume last Claude session
luv -r my-repo 42

# Clean up fully-merged workspaces
luv --clean

How it works

1. Clones the repo into ~/prs/{repo}-{number}/
2. Creates a new branch luv-{number}
3. Trusts the project in Claude Code config
4. Launches Claude with Opus 4.8 at max effort; prompt-less sessions auto-run /effort ultracode as their first input to enter ultracode mode

All workspaces live under ~/prs/. The number comes from the repo's GitHub issue counter to avoid collisions.

Commands

Command	Description
luv --init	Configure default GitHub org
luv [org/]<repo> [prompt...]	Create a new workspace and launch Claude
luv [org/]<repo> <number> [prompt]	Reopen an existing workspace
luv -l <PR URL> [prompt]	Open any GitHub PR by URL
luv [org/]<repo> -pr <number> [prompt]	Open a PR by repo + number
luv --clean	Delete workspaces where the branch is fully pushed/merged
luv --clean -f	Force delete all workspaces
luv --clean --safe -f	Force delete only workspaces older than 24h

Flags

Flag	Description
-n	Navigate: open a shell instead of Claude
-r	Resume: resume the last Claude session
-p	Launch Claude in plan permission mode (default: bypassPermissions)
-nit	Non-interactive: run claude -p <prompt> and exit (no REPL); streams stream-json events to stdout
-m MODEL	Claude model to use (default: claude-opus-4-8); passed through to claude --model, so aliases like opus/sonnet/haiku work
-e	Env: pass LUV_* environment variables (with prefix stripped) into the session
-f, --force	Skip safety checks (with --clean)
--safe	With --clean -f, only delete workspaces older than 24h (mtime)

Docker dev environments

If a repo contains .luv/settings.json with a compose_file key, luv automatically starts a Docker Compose environment and runs Claude inside the dev-environment container.

Setup

1. Create .luv/settings.json in your repo:

{
  "compose_file": ".luv/docker-compose.yml"
}

The compose_file path is relative to the repo root.

2. Create the Docker Compose file:

services:
  dev-environment:
    image: your-org/dev-env:latest
    volumes:
      - .:/workspace
    working_dir: /workspace
    stdin_open: true
    tty: true
    depends_on:
      - postgres

  postgres:
    image: postgres:16
    environment:
      POSTGRES_PASSWORD: dev

The dev-environment service must have Claude Code installed in its image.

How Docker mode works

1. Detects .luv/settings.json with compose_file key
2. Tears down any stale environment from a previous run
3. Starts docker compose up -d --build with a unique project name (luv-{repo}-{number}) for network/volume isolation
4. Verifies the dev-environment service is running
5. Runs Claude inside the container via docker compose exec
6. The repo is volume-mounted, so all file changes and git commits are visible on the host
7. On exit (including Ctrl-C), tears down the environment with docker compose down -v

Docker mode works with all flags: -n opens a bash shell in the container, -r resumes a Claude session in the container.

Workspace cleanup

luv --clean scans ~/prs/ and safely removes workspaces that are fully pushed. It checks:

• Working tree is clean (no uncommitted changes)
• No unpushed commits
• If the remote branch is gone, verifies the PR was merged and local HEAD matches

Use luv --clean -f to skip all safety checks and delete everything. Add --safe (i.e. luv --clean --safe -f) to restrict force-delete to workspaces whose folder mtime is older than 24 hours, leaving recently-touched workspaces alone.

Configuration

Run luv --init to set your default GitHub org. This saves to ~/.luv/config.json.

You can also pass org/repo inline to override the default for any command (e.g., luv other-org/my-repo).
