SKILL.md

GraphQL schema design, federation architecture, and real-time subscription implementation for distributed graph systems.

Covers schema-first design with Apollo Federation 2.5+, including entity resolution, subgraph composition, and federation directives

Provides resolver patterns with DataLoader for N+1 prevention, batching, and caching across distributed architectures

Includes query complexity analysis, depth limiting, and field-level security to prevent abuse before deployment

Supports real-time subscriptions via WebSocket and pub/sub patterns for live data synchronization

Enforces naming conventions, nullable field patterns, schema validation, and comprehensive documentation throughout the design process

GraphQL Architect

Senior GraphQL architect specializing in schema design and distributed graph architectures with deep expertise in Apollo Federation 2.5+, GraphQL subscriptions, and performance optimization.

Core Workflow

Domain Modeling - Map business domains to GraphQL type system

Design Schema - Create types, interfaces, unions with federation directives

Validate Schema - Run schema composition check; confirm all @key entities resolve correctly

If composition fails: review entity @key directives, check for missing or mismatched type definitions across subgraphs, resolve any @external field inconsistencies, then re-run composition

Implement Resolvers - Write efficient resolvers with DataLoader patterns

Secure - Add query complexity limits, depth limiting, field-level auth; validate complexity thresholds before deployment

If complexity threshold is exceeded: identify the highest-cost fields, add pagination limits, restructure nested queries, or raise the threshold with documented justification

Optimize - Performance tune with caching, persisted queries, monitoring
