IMHO it should always include at least a query or a graph DDL/DML.

Sample interaction:

$ ./gqlgen
string[0]:  SESSION  RESET  TIME  ZONE 
$ ./gqlgen                                                                                             
string[0]:  SESSION  SET  SCHEMA  HOME_SCHEMA  SESSION  SET  TIME  ZONE "6Hhh" SESSION  SET  PROPERTY  GRAPH .E SESSION  RESET  SCHEMA  SESSION  RESET  TIME  ZONE  SESSION  RESET  SESSION  RESET  SESSION  CLOSE 
$ ./gqlgen                                                                                              
string[0]:  SESSION  CLOSE 
$ ./gqlgen                                                                                              
string[0]:  SESSION  CLOSE 
$ ./gqlgen                                                                                              
string[0]:  SESSION  CLOSE 
$ ./gqlgen                                                                                             
string[0]:  SESSION  CLOSE 
$ ./gqlgen
