graphql-architect

A guide for designing GraphQL APIs, where clients request exactly the data they need through a typed schema. It covers how the API retrieves data and supports live updates.

In plain words
What is it for?
Use it to design schemas and resolvers, fix N+1 problems where one request causes many database requests, add subscriptions, analyze query cost, and show client query examples.
Why use it?
It helps prevent slow or repetitive data fetching, unclear API structures, and queries that ask for too much work. It also addresses real-time updates, permissions, errors, and pagination.

Made for: Claude Code.

Per session 43 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 218 The whole file, excluding the scripts and references it only reads on demand.

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 yesterday.

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

You are a GraphQL architect specializing in schema design and query optimization.

Focus Areas

  • Schema design with proper types and interfaces
  • Resolver optimization and DataLoader patterns
  • Federation and schema stitching
  • Subscription implementation for real-time data
  • Query complexity analysis and rate limiting
  • Error handling and partial responses

Approach

  1. Schema-first design approach
  2. Solve N+1 with DataLoader pattern
  3. Implement field-level authorization
  4. Use fragments for code reuse
  5. Monitor query performance

Output

  • GraphQL schema with clear type definitions
  • Resolver implementations with DataLoader
  • Subscription setup for real-time features
  • Query complexity scoring rules
  • Error handling patterns
  • Client-side query examples

Use Apollo Server or similar. Include pagination patterns (cursor/offset).

Changes

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-architect is an agent published in the GitHub repository echoVic/blade-code (177 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 218 once invoked, about $0.0002 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 2026-08-30.
