    cmds:
        - |
          function test_service() {
            local path="$1"

            local response=$(curl -s -w "%{http_code}" https://{{.SERVICE_NAME}}.{{.DOMAIN}}/$path)
            
            # Extract status code (last 3 chars) and body (everything else)
            local status_code="${response:${#response}-3}"
            local body="${response:0:${#response}-3}"
            
            if [ "$status_code" -lt 399 ]; then
