Base directory for this skill: ${CLAUDE_PLUGIN_BASE_DIR}

Your Task

Guide the user through installing bitwize-music plugin dependencies based on their Python environment and requested components.

Setup Assistant

You help users install and verify plugin dependencies.

Step 1: Detect Environment

Run these checks in parallel:

# Python version
python3 --version

# Check if externally managed
python3 -c "import sysconfig; print(sysconfig.get_path('purelib'))" 2>&1 | grep -q "/usr" && echo "EXTERNALLY_MANAGED" || echo "USER_MANAGED"

# Check for pipx
command -v pipx >/dev/null 2>&1 && echo "pipx: installed" || echo "pipx: not installed"

# Check for venv support
python3 -m venv --help >/dev/null 2>&1 && echo "venv: supported" || echo "venv: not supported"

# Platform
uname -s

---

Step 2: Check Component Status

IMPORTANT: Run these checks sequentially, not in parallel. If one check fails, continue with the remaining checks to show complete status.

CRITICAL: Always check the venv, not system Python!

# Set venv path (macOS/Linux/WSL uses bin/python3; native Windows uses Scripts/python.exe)
VENV_PYTHON=~/.bitwize-music/venv/bin/python3
[ -f "$VENV_PYTHON" ] || VENV_PYTHON=~/.bitwize-music/venv/Scripts/python.exe

# Check if venv exists
if [ -f "$VENV_PYTHON" ]; then
    echo "✅ Venv exists at ~/.bitwize-music/venv"

    # Check each component in the venv
    $VENV_PYTHON -c "import mcp; print('✅ mcp installed')" 2>&1 || echo "❌ mcp not installed"
    $VENV_PYTHON -c "import matchering; print('✅ matchering installed')" 2>&1 || echo "❌ matchering not installed"
    $VENV_PYTHON -c "import boto3; print('✅ boto3 installed')" 2>&1 || echo "❌ boto3 not installed"
    $VENV_PYTHON -c "from playwright.sync_api import sync_playwright; print('✅ playwright installed')" 2>&1 || echo "❌ playwright not installed"

    # Check for version drift against requirements.txt
    $VENV_PYTHON -c "
import importlib.metadata, pathlib
reqs = pathlib.Path('${CLAUDE_PLUGIN_ROOT}/requirements.txt').read_text()
stale = []
for line in reqs.splitlines():
    line = line.split('#')[0].strip()
    if not line or '==' not in line:
        continue
    name, _, ver = line.partition('==')
    name = name.split('[')[0].strip()
    try:
        installed = importlib.metadata.version(name)
        if installed != ver:
            stale.append(f'  {name}: {installed} → {ver}')
    except importlib.metadata.PackageNotFoundError:
        stale.append(f'  {name}: missing (needs {ver})')
if stale:
    print('⚠️  Version drift detected:')
    print('\n'.join(stale))
else:
    print('✅ All package versions match requirements.txt')
" 2>&1
else
    echo "❌ Venv not found at ~/.bitwize-music/venv"
    echo "   Run: python3 -m venv ~/.bitwize-music/venv   # macOS/Linux/WSL"
    echo "   Or:  py -3 -m venv ~/.bitwize-music/venv      # Windows"
