GraphQL schema security auditor

This is a design review of the pasted text, not a penetration test. It never queries an endpoint; there is no live mode. Depth, complexity, and rate limits do not appear in a schema or introspection result, so nothing here can tell you whether a server enforces them, and introspection carries no directive declarations, so @auth style guards are invisible to the audit. A clean report means the paste shows no obvious design risks, nothing stronger than that.
