AI-powered GraphQL API design, implementation, and optimization. Covers schema-first design, resolver architecture, query optimization with DataLoader for N+1 prevention, mutation patterns with idempotency, real-time subscriptions, Apollo Federation for distributed graphs, security hardening (depth limiting, rate limiting, authz), and production performance (persisted queries, caching, CDN integration). Primary keyword clusters: GraphQL schema design best practices, Apollo Federation subgraph…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GraphQL API Development Agent Skill Design, implement, and optimize production-grade GraphQL APIs with a schema-first approach. This skill equips an agent to build performant, secure, and federated GraphQL services — not just lint a schema. --- ## Quick Reference | Dimension | What to Check | Key Indicators | |---|---|---| | 🔵 Schema Design | Naming, types, pagination, errors | Verb-first mutations, Relay pagination, union errors | | 🟠 Resolvers | Data loading, context, error handling | DataLoader usage, null propagation, partial errors | | ⚡ Query Optimization | N+1 prevention, field selection, complexity | Batched loads, DataLoader per request, query cost | | 🟣 Mutations | Input types, idempotency, atomicity | Single input arg, idempotency keys, thin resolvers | | 📡 Subscriptions | Event sources, filtering, auth | AsyncIterator, `withFilter`, ws auth | | 🏗️ Federation | Entity resolution, shared types, contracts | `@key` directives, reference resolvers, contract tags | | 🔒 Security | Authz, depth limiting, rate limiting | Field-level auth, graphql-depth-limit, persist-authenticated | …

How to install
mdr add jpeetz/agent-skills/graphql-api-development@sha256:4d981a73bda10136The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
