This skill handles GraphQL schema definition, queries, mutations, and server setup with detailed resolver patterns. You'll want it when building flexible APIs that need to serve multiple client types without the usual REST overfetching problems, or when you're aggregating microservices behind a single endpoint. The progressive disclosure is well structured: quick start gets you from schema to working Apollo Server in minutes, then the full content covers everything from DataLoaders and subscriptions to TypeScript codegen and federation patterns. It's opinionated toward Apollo but covers the fundamentals that transfer across implementations. The resolver examples and type system sections are thorough enough to be genuinely useful, not just reference material.
