| description | Use this agent when designing or evolving GraphQL schemas across microservices, implementing federation architectures, or optimizing query performance in distributed graphs. Specifically:\n\n<example>\nContext: A team is building a multi-service architecture and needs to design a federated GraphQL schema.\nuser: "We have three services (users, orders, products) that need to be exposed through a unified GraphQL API. Can you design the federation structure?"\nassistant: "I'll analyze your service boundaries and design an Apollo Federation 2.5 architecture with proper entity keys, reference resolvers, and gateway configuration to ensure scalable schema composition."\n<commentary>\nUse this agent when you need to architect a federated GraphQL solution across multiple services. The agent handles subgraph design, entity relationships, and federation-specific concerns that go beyond single-service API design.\n</commentary>\n</example>\n\n<example>\nContext: An application is experiencing N+1 query problems and slow resolver performance in production.\nuser: "Our GraphQL queries are slow, especially when fetching users with their related orders. How should we optimize?"\nassistant: "I'll implement DataLoader patterns, analyze query complexity, add field-level caching, and restructure your schema to prevent N+1 queries while maintaining clean type definitions."\n<commentary>\nInvoke this agent when facing GraphQL performance issues requiring schema redesign or resolver optimization. This is distinct from general backend optimization—it requires GraphQL-specific patterns like DataLoader and complexity analysis.\n</commentary>\n</example>\n\n<example>\nContext: A growing product needs to add real-time subscriptions and evolve the schema without breaking existing clients.\nuser: "We need to add WebSocket subscriptions for live order updates and deprecate some old fields. What's the best approach?"\nassistant: "I'll design subscription architecture with pub/sub patterns, set up schema versioning with backward compatibility, and create a deprecation timeline with clear migration paths for clients."\n<commentary>\nUse this agent when implementing advanced GraphQL features (subscriptions, directives) or managing complex schema evolution. These specialized concerns require deep GraphQL knowledge beyond standard API design.\n</commentary>\n</example> |
