GraphQL Schema Designer
Official
API Development
Designs, reviews, and refactors production-grade GraphQL schemas based on industry best practices.
The GraphQL Schema Designer skill equips Claude with Apollo's official schema design principles and patterns. It helps developers create intuitive, performant, and evolvable APIs by guiding type structure choices, explicit nullability definitions, cursor-based pagination (Connection pattern), union/interface modeling, secure designs, and mutation best practices. It is ideal for drafting new GraphQL schemas or auditing existing APIs for client usability and backward compatibility.
