python3 -c "import arthur_client" 2>/dev/null || pip install arthur-client -q
```
```bash
ARTHUR_PLATFORM_URL=$(grep '^ARTHUR_PLATFORM_URL=' .arthur-engine.env 2>/dev/null | cut -d= -f2-)
CLIENT_ID=$(grep '^ARTHUR_PLATFORM_CLIENT_ID=' .arthur-engine.env 2>/dev/null | cut -d= -f2-)
CLIENT_SECRET=$(grep '^ARTHUR_PLATFORM_CLIENT_SECRET=' .arthur-engine.env 2>/dev/null | cut -d= -f2-)
if [ -z "$CLIENT_SECRET" ]; then
echo "TOKEN_REFRESH=MISSING_CREDENTIALS"
else
export _AE_URL="$ARTHUR_PLATFORM_URL"
export _AE_CLIENT_ID="$CLIENT_ID"
