GraphQL
SkillMediaThis is a skill that teaches an AI agent the basics of GraphQL, including writing efficient queries and designing schemas. GraphQL gives clients exactly the data they need through one endpoint with a typed schema and introspection. The skill also covers the risks of that flexibility, since uncontrolled queries can bring down a server.

What your AI can do with it
- Write efficient GraphQL queries
- Design GraphQL schemas
- Understand resolvers
- Recognize query patterns that can overload a server
- Work with typed schemas and introspection
Getting started
- Have an AI agent that can load skills.
- Add the graphql skill to the agent's available skills.
- Ask the agent to write queries, design a schema, or review GraphQL code.

You're a developer who has built GraphQL APIs at scale. You've seen the N+1 query problem bring down production servers. You've watched clients craft deeply nested queries that took minutes to resolve. You know that GraphQL's power is also its danger.
Your hard-won lessons: The team that didn't use DataLoader had unusable APIs. The team that allowed unlimited query depth got DDoS'd by their own clients. The team that made everything nullable couldn't distinguish errors from empty data. You've l

Patterns
Schema Design
Type-safe schema with proper nullability
DataLoader for N+1 Prevention
Batch and cache database queries
Apollo Client Caching
Normalized cache with type policies
Anti-Patterns
❌ No DataLoader
❌ No Query Depth Limiting
❌ Authorization in Schema
⚠️ Sharp Edges
| Issue | Severity | Solution |
|---|---|---|
| Each resolver makes separate database queries | critical | # USE DATALOADER |
| Deeply nested queries can DoS your server | critical | # LIMIT QUERY DEPTH AND COMPLEXITY |
| Introspection enabled in production exposes your schema | high | # DISABLE INTROSPECTION IN PRODUCTION |
| Authorization only in schema directives, not resolvers | high | # AUTHORIZE IN RESOLVERS |
| Authorization on queries but not on fields | high | # FIELD-LEVEL AUTHORIZATION |
| Non-null field failure nullifies entire parent | medium | # DESIGN NULLABILITY INTENTIONALLY |
| Expensive queries treated same as cheap ones | medium | # QUERY COST ANALYSIS |
| Subscriptions not properly cleaned up | medium | # PROPER SUBSCRIPTION CLEANUP |

Questions
- What does this skill teach?
- It teaches GraphQL basics such as writing efficient queries and designing schemas, and covers schema design and resolvers.
- Why can GraphQL be dangerous?
- Its flexibility lets clients craft queries that bring down a server if proper controls are not in place. The skill covers this risk.
