Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00051 | $0.05978 |
| Opus 5.5 | $0.00020 | $0.02391 |
| Sonnet 5.5 | $0.00010 | $0.01196 |
| Haiku 4.5 | $0.00005 | $0.00598 |
Grade A, and why
graphql scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to graphql — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 1,075 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GraphQL
GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server.
This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully.
2025 lesson: GraphQL isn't always the answer. For simple CRUD, REST is simpler. For high-performance public APIs, REST with caching wins. Use GraphQL when you have complex data relationships and diverse client needs.
Principles
- Schema-first design - the schema is the contract
- Prevent N+1 queries with DataLoader
- Limit query depth and complexity
- Use fragments for reusable selections
- Mutations should be specific, not generic update operations
- Errors are data - use union types for expected failures
- Nullability is meaningful - design it intentionally
Capabilities
- graphql-schema-design
- graphql-resolvers
- graphql-federation
- graphql-subscriptions
- graphql-dataloader
- graphql-codegen
- apollo-server
- apollo-client
- urql
Scope
- database-queries -> postgres-wizard
- authentication -> authentication-oauth
- rest-api-design -> backend
- websocket-infrastructure -> backend
Tooling
Server
- @apollo/server - When: Apollo Server v4 Note: Most popular GraphQL server
- graphql-yoga - When: Lightweight alternative Note: Good for serverless
- mercurius - When: Fastify integration Note: Fast, uses JIT
Client
- @apollo/client - When: Full-featured client Note: Caching, state management
- urql - When: Lightweight alternative Note: Smaller, simpler
- graphql-request - When: Simple requests Note: Minimal, no caching
Tools
- graphql-codegen - When: Type generation Note: Essential for TypeScript
- dataloader - When: N+1 prevention Note: Batches and caches
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

graphql is a skill published in the GitHub repository beel-collab/presets.dev (3 stars, last pushed 5mo ago), licensed MIT. It adds 51 tokens to every session and 5,978 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to graphql, differing in 16 lines, and is treated as a copy.
