Build and configure a GraphQL API backed by Neo4j using @neo4j/graphql v7 (current) or v5 (LTS). Covers Neo4jGraphQL constructor, getSchema(), assertIndexesAndConstraints(), type definitions with @node, @relationship (IN/OUT/UNDIRECTED), @cypher for custom resolvers, @authorization/@authentication for JWT/JWKS security, auto-generated queries/mutations, OGM programmatic access, subscriptions via CDC, and Apollo Federation. Use when writing typeDefs, securing fields, or wiring Neo4j to Apollo Server. Does NOT handle raw Cypher outside resolvers — use neo4j-cypher-skill. Does NOT cover Spring Data Neo4j entity mapping — use neo4j-spring-data-skill.
Use when creating, modifying, or removing API endpoints on a Datex Studio branch. Covers the full lifecycle: requirements, prerequisite creation (datasources, flows), endpoint wiring, and verification. Trigger for: "create an endpoint", "expose this flow as an API", "add an API for X", "modify endpoint", "remove endpoint", "change endpoint alias", "create an API that does X".
gRPC service development in .NET for high-performance inter-service communication
Use when a PinMe project (Worker TypeScript) needs to integrate user authentication — creating email/password users, verifying id_tokens, querying user info, or listing users via Identity Platform auth proxy APIs.
Domain-Driven Design patterns for TypeScript. Use when implementing ubiquitous language, value objects, entities, aggregates, domain events, domain services, or bounded contexts. Only applies to projects that explicitly use DDD. Do NOT use for simple CRUD or projects without domain modeling.
Configure Redis for caching and data storage. Set up clustering, persistence, and Sentinel. Use when implementing Redis caching or queues.
Guidelines for fixing Motoko compiler warnings (moc). Use when asked to fix, suppress, or clean up Motoko compiler warnings from `dfx build --check`.
General performance optimization techniques for Motoko. Reducing allocations, efficient Text building, fixed-width arithmetic, block processing, async patterns, and more. Load when you need to improve hot paths or reduce overhead without changing behavior.
Analyze a user's codebase to verify it can use Runway's public API (server-side requirement)
Design complete API contracts in OpenAPI 3.0/3.1 YAML with endpoints, schemas, security, pagination, error handling, and RFC 7807 problem details. Use when asking to design an API, create an OpenAPI spec, define API endpoints, write API contracts, or generate a Swagger specification.
NestJS best practices and architecture patterns for building production-ready applications. This skill should be used when writing, reviewing, or refactoring NestJS code to ensure proper patterns for modules, dependency injection, security, and performance.
CCXT cryptocurrency exchange library for Go developers. Covers both REST API (standard) and WebSocket API (real-time). Helps install CCXT, connect to exchanges, fetch market data, place orders, stream live tickers/orderbooks, handle authentication, and manage errors in Go projects. Use when working with crypto exchanges in Go applications, microservices, or trading systems.
