GraphQL schema and federation expert specializing in resolver optimization, subscriptions, and API gateway patterns

What it does

Graphql Architect is an agent skill from majiayu000/claude-skill-registry. GraphQL schema and federation expert specializing in resolver optimization, subscriptions, and API gateway patterns

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Backend & APIs, covering GraphQL. It works with GraphQL. The repository describes itself as: Searchable Claude Code skills catalog with source-linked guides and generated registry artifacts. The licence is MIT.

When your agent uses it

  • Tasks that involve GraphQL

Example prompts

  • “/graphql-architect”

What it can do on your machine

Read from SKILL.md and the folder at commit 2d14a69. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript and graphql).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Graphql Architect loads about 1.6k tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 413 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

GraphQL schema and federation expert specializing in resolver optimization, subscriptions, and API gateway patterns

GraphQL Architect Skill

Purpose

Provides expert GraphQL architecture expertise specializing in schema design, federation patterns, resolver optimization, and real-time subscriptions. Builds performant, type-safe GraphQL APIs with N+1 prevention, efficient caching, and scalable API gateway patterns across distributed systems.

When to Use

  • Designing GraphQL schema from scratch for new APIs
  • Implementing GraphQL federation across multiple services
  • Optimizing resolvers to prevent N+1 queries (DataLoader implementation)
  • Building real-time features with GraphQL subscriptions
  • Migrating from REST to GraphQL or designing hybrid REST+GraphQL APIs
  • Implementing GraphQL API gateway patterns

Quick Start

Invoke this skill when:

  • Designing new GraphQL schemas or federation architecture
  • Solving N+1 query performance issues
  • Implementing real-time subscriptions
  • Migrating REST APIs to GraphQL

Do NOT invoke when:

  • Simple REST API is sufficient (use api-designer)
  • Database schema design without API layer (use database-administrator)
  • Frontend data fetching only (use frontend-developer)

Core Capabilities

Schema Design
  • Creating type-safe GraphQL schemas with best practices
  • Implementing pagination patterns (Relay, offset-based)
  • Designing mutations with input validation and error handling
  • Managing schema evolution and backward compatibility
Federation Architecture
  • Implementing Apollo Federation for microservices
  • Configuring schema stitching for service composition
  • Managing cross-service queries and mutations
  • Setting up API gateways for schema composition
Resolver Optimization
  • Implementing DataLoader for N+1 prevention
  • Caching strategies at resolver and field levels
  • Query complexity analysis and depth limiting
  • Persisted queries for production optimization
Real-Time Subscriptions
  • Implementing WebSocket-based subscriptions
  • Managing subscription lifecycle and cleanup
  • Integrating with event-driven backends
  • Handling subscription authentication and authorization

│
├─ Nested resolvers (users → posts → comments)?
│  └─ Multi-level DataLoaders
│
└─ Aggregations or counts?
   └─ Separate DataLoader for counts

Core Workflow: DataLoader Implementation

Problem: N+1 queries killing performance

typescript
// WITHOUT DataLoader - N+1 problem
const resolvers = {
  Post: {
    author: async (post, _, { db }) => {
      // Executed once per post (N+1 problem!)
      return db.User.findByPk(post.userId);
    }
  }
};
// Query for 100 posts triggers 101 DB queries

Solution: Batch with DataLoader

typescript
import DataLoader from 'dataloader';

// Create loader per request (important!)
function createLoaders(db) {
  return {
    userLoader: new DataLoader(async (userIds) => {
      const users = await db.User.findAll({
        where: { id: userIds }
      });
      // Return in same order as requested IDs
      const userMap = new Map(users.map(u => [u.id, u]));
      return userIds.map(id => userMap.get(id));
    })
  };
}

// Resolver using DataLoader
const resolvers = {
  Post: {
    author: (post, _, { loaders }) => {
      return loaders.userLoader.load(post.userId);
    }
  }
};
// Same query now triggers 2 queries total!

Quick Reference: Schema Best Practices

Pagination Pattern (Relay-style)
graphql
type Query {
  users(first: Int, after: String, last: Int, before: String): UserConnection!
}

type UserConnection {
  edges: [UserEdge!]!
  pageInfo: PageInfo!
  totalCount: Int!
}

type UserEdge {
  node: User!
  cursor: String!
}

type PageInfo {
  hasNextPage: Boolean!
  hasPreviousPage: Boolean!
  startCursor: String
  endCursor: String
}
Error Handling Pattern
graphql
type Mutation {
  createUser(input: CreateUserInput!): CreateUserPayload!
}

type CreateUserPayload {
  user: User
  errors: [UserError!]!
}

type UserError {
  field: String
  message: String!
  code: ErrorCode!
}

enum ErrorCode {
  VALIDATION_ERROR
  NOT_FOUND
  UNAUTHORIZED
  CONFLICT
}
