Starting point for schema generation? Plugin?

Not sure if this is really an "issue", so feel free to move it to the discussions if it fits better there.

I am looking for a starting point for a plugin (?) that generates queries/mutations out of the existing schema, or more specifically adds to the specific schema. Something similar to what dgraph is doing (https://dgraph.io/docs/graphql/queries/search-filtering/). It generates automatically queries/mutations and input types based on the defined types (and partially based on a directive). Looking at the architecture this seems possible with gqlgen but I somehow lack a good starting point.

Any pointers? I can try to enhance the docs afterwards if needed.
