apollo-graphql

apollo-graphql is a cursor rule for coding agents from sanjeed5/awesome-cursor-rules-mdc. It costs 297 tokens per session, scanned A, original, CC0-1.0.

Coding guidelines for Apollo GraphQL, a toolset for APIs where clients request the data they need. They cover both Apollo Server and Apollo Client, including how to design and organise the API schema.

In plain words
What is it for?
Defining GraphQL schemas with SDL, documenting types and queries, organising server and client code, and applying consistent practices to Apollo applications.
Why use it?
They help teams create a clear API contract before implementation and avoid schemas and resolver code that are difficult to understand, review, or maintain.

Cursor rule

About the project

awesome-cursor-rules-mdc is a generator that creates Cursor MDC rule files from structured library information, using semantic search and language models to gather and organize guidance. Developers use it to produce reusable rules for libraries in Cursor, and the catalogue includes 200 of those rules.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

apollo-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 5d 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.

What it actually says

apollo-graphql Best Practices

This guide outlines our definitive best practices for developing with Apollo GraphQL, covering both server-side (Apollo Server 5) and client-side (Apollo Client) implementations. Adhering to these rules ensures consistency, performance, and maintainability across our GraphQL ecosystem.

1. Schema Design and Organization

Your GraphQL schema is the contract. Design it meticulously, document it thoroughly, and organize it logically.

1.1 Schema-First Development with SDL

Always start by defining your schema using Schema Definition Language (SDL). This forces clear API design before implementation.

❌ BAD

// Implicit schema definition through resolvers
const resolvers = {
  Query: {
    users: () => [{ id: '1', name: 'Alice' }],
  },
};
// Schema is inferred or built programmatically, harder to review

✅ GOOD

# schema/user.graphql
"""Represents a user in the system."""
type User {
  id: ID!
  name: String!
  email: String
}

type Query {
  """Fetches a list of all users."""
  users: [User!]!
  """Fetches a single user by their ID."""
  user(id: ID

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.
