golang-graphql

The golang-graphql skill provides expert guidance for implementing GraphQL APIs in Go using industry-standard libraries like gqlgen and graphql-go. It helps developers build production-ready GraphQL servers by following schema-first design principles, implementing efficient resolvers, and avoiding common pitfalls like N+1 query problems. The skill automatically detects when a project uses GraphQL libraries and provides context-aware assistance for schema design, resolver implementation, and server configuration.

This skill emphasizes best practices critical for production GraphQL services: deliberate schema design with explicit nullability, cursor-based pagination using Relay connections, DataLoader patterns to batch database access and prevent N+1 queries, and query complexity limits to protect against expensive operations. It supports both gqlgen (code generation with compile-time type safety) and graphql-go (reflection-based with simpler builds), helping teams choose the right tool based on project size and requirements. The skill includes specialized modes for building new features and reviewing existing codebases for performance and security issues.

Ideal for backend engineers building GraphQL APIs in Go, technical leads architecting new services, or teams migrating from REST to GraphQL. The skill assists with writing SDL schemas, generating and implementing resolvers, setting up Apollo Federation for microservices, handling subscriptions for real-time features, and integrating GraphQL endpoints into existing Go HTTP servers. It's particularly valuable for teams prioritizing type safety, performance optimization, and maintainable schema evolution in production environments.
