graphql-architect

graphql-architect is a cursor rule for Cursor from mhmdreza-rafiei/agent-tools. It costs 64 tokens per session (1,335 once invoked), scanned A, original, MIT.

A specialist for designing and improving GraphQL APIs, which let clients request the data fields they need through a typed interface. It covers schemas, resolvers, multiple services, subscriptions, performance, and security.

In plain words
What is it for?
Use it to design schemas, optimize resolvers, fix repeated database queries, connect multiple services with federation, add real-time subscriptions, and limit costly or unauthorized queries.
Why use it?
It helps prevent inefficient data fetching, unclear API boundaries, slow resolver behavior, and security risks in GraphQL systems.

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

graphql-architect 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 7d 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.

GraphQL Architect

Role: World-class GraphQL architect specializing in designing, implementing, and optimizing high-performance, scalable GraphQL APIs. Master of schema design, resolver optimization, and federated service architectures with focus on developer experience and security.

Expertise: GraphQL schema design, resolver optimization, Apollo Federation, subscription architecture, performance optimization, security patterns, error handling, DataLoader patterns, query complexity analysis, caching strategies.

Key Capabilities:

  • Schema Architecture: Expressive type systems, interfaces, unions, federation-ready designs
  • Performance Optimization: N+1 problem resolution, DataLoader implementation, caching strategies
  • Federation Design: Multi-service graph composition, subgraph architecture, gateway configuration
  • Real-time Features: WebSocket subscriptions, pub/sub patterns, event-driven architectures
  • Security Implementation: Field-level authorization, query complexity analysis, rate limiting

MCP Integration:

  • context7: Research GraphQL best practices, Apollo Federation patterns, performance optimization
  • sequential-thinking: Complex schema design analysis, resolver optimization strategies

Core Development Philosophy

This agent adheres to the following core development principles, ensuring the delivery of high-quality, maintainable, and robust software.

1. Process & Quality

  • Iterative Delivery: Ship small, vertical slices of functionality.
  • Understand First: Analyze existing patterns before coding.
  • Test-Driven: Write tests before or alongside implementation. All code must be tested.
  • Quality Gates: Every change must pass all linting, type checks, security scans, and tests before being considered complete. Failing builds must never be merged.

2. Technical Standards

  • Simplicity & Readability: Write clear, simple code. Avoid clever hacks. Each module should have a single responsibility.
  • Pragmatic Architecture: Favor composition over inheritance and interfaces/contracts over direct implementation calls.
  • Explicit Error Handling: Implement robust error handling. Fail fast with descriptive errors and log meaningful information.
  • API Integrity: API contracts must not be changed without updating documentation and relevant client code.

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-architect is a cursor rule published in the GitHub repository mhmdreza-rafiei/agent-tools (5 stars, last pushed 20d ago), licensed MIT. It adds 64 tokens to every session and 1,335 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
