Claude Code Agent: GraphQL Architect — Schema & Resolver Design

What it is

GraphQL Architect is a Claude Code agent template focused on GraphQL development. It provides specialized guidance for schema design, resolver implementation patterns, subscription handling, Apollo Federation setup, and query performance optimization. When installed, it activates automatically when Claude detects GraphQL-related files or conversations in your project.

The agent targets backend developers building GraphQL APIs who want opinionated guidance on schema structure, N+1 query prevention, and federation architecture without consulting documentation for every decision.

How it saves time or tokens

GraphQL development involves many design decisions: how to structure types, when to use interfaces vs unions, how to handle pagination, and how to avoid N+1 queries. This agent front-loads best practices so Claude's suggestions follow established patterns from the start. You spend fewer tokens correcting anti-patterns and more on building features. The agent also includes resolver boilerplate generators that produce production-ready code.

How to use

1. Install the agent template:

npx claude-code-templates@latest --agent api-graphql/graphql-architect --yes

1. The agent activates automatically when you work on GraphQL files (.graphql, .gql, schema definitions).

1. Ask Claude about schema design, and it will apply GraphQL best practices:

Design a schema for an e-commerce API with products, orders, and users.
Include pagination, filtering, and proper error handling.

Example

A schema following the agent's recommended patterns:

type Query {
  products(first: Int, after: String, filter: ProductFilter): ProductConnection!
  product(id: ID!): Product
}

type ProductConnection {
  edges: [ProductEdge!]!
  pageInfo: PageInfo!
  totalCount: Int!
}

type ProductEdge {
  node: Product!
  cursor: String!
}

input ProductFilter {
  category: String
  minPrice: Float
  maxPrice: Float
}

type Product {
  id: ID!
  name: String!
  price: Float!
  category: Category!
}

Common pitfalls

• Over-nested schemas create deep resolver chains that are hard to optimize; keep nesting to 3-4 levels maximum
• Missing DataLoader implementation causes N+1 queries; the agent recommends DataLoader patterns but you must implement the batching function
• Federation requires careful planning of entity ownership; splitting types across services without a clear ownership model leads to circular dependencies
