Hi Apollo team  
I see rover subgraph check command is there to check subgraph for schema and linting checks, so I get it you have your own rules but can they be modified.  
Suppose I want a rule that, inside query user cannot put return type as scalar value, it should be always object  
or any other kind of checks  
example -  
wrong —  
type query{  
names: String  
}  
correct –  
type query {  
names: allNames  
}  
type allNames{  
name: string  
}

As of writing we currently do not support custom lint rules. You can configure the existing rules in your Studio graph settings and in that UI we have a form to requests new rules so that would be a good place to submit that request

Good news! GraphOS shipped with the ability to do custom checks and you can use that to implement a custom schema linter!
