This is kind of a stretch, but especially if there were multiple operations beyond the "volumeDelete", the GraphQL definitely worsens readability here.

For someone reviewing and approving LLM calls or just double-checking before running a script or bash history, it would be a lot more readable if it were compliant with HTTP norms: curl -X DELETE example.com/api/volumes/uuid123 would make it very obvious that something was going to be deleted at the front and then what it is at the end of the command.
