Spring for GraphQL - building GraphQL APIs with Spring Boot. Covers queries, mutations, subscriptions, @BatchMapping, DataLoader, and security. USE WHEN: user mentions "spring graphql", "@QueryMapping", "@MutationMapping", "@SubscriptionMapping", "@BatchMapping", "GraphQL Spring Boot", "N+1 GraphQL" DO NOT USE FOR: REST APIs - use standard Spring MVC, standalone GraphQL - use `graphql-java` skill
Optimize Entity Framework Core queries by fixing N+1 problems, choosing correct tracking modes, using compiled queries, and avoiding common performance traps. Use when EF Core queries are slow, generating excessive SQL, or causing high database load.
Module organization patterns including ports and adapters (hexagonal), module communication, and data isolation. Use when structuring modular monoliths, defining module boundaries, setting up inter-module communication, or isolating database contexts. Includes MediatR patterns for internal events.
Lead complex software implementation, architecture decisions, and reliable delivery across any modern technology stack. Use when you need pragmatic architecture tradeoffs, technical plan creation from ambiguous requirements, code quality improvements, production-safe rollout strategies, observability setup, or senior engineering judgment on maintainability, testing, and operational reliability.
Build backend API endpoints, services, and database changes. Use for backend-only work like new API routes, business logic, database schema changes, or microservice patterns. Activates the Architecture Council for significant API decisions.
Build and troubleshoot Box integrations for uploads, folders, folder listings, downloads and previews, shared links, collaborations, search, metadata, event-driven automations, and Box AI retrieval flows. Use when the agent needs to add Box APIs or SDKs to an app, wire Box-backed document workflows, organize or share content, react to new files, or fetch Box content for search, summarization, extraction, or question-answering.
Designs REST and GraphQL APIs including endpoints, error handling, versioning, and documentation. Use when creating new APIs, designing endpoints, reviewing API contracts, or when asked about REST, GraphQL, or API patterns.
Use when you need to implement or improve Java logging and observability — including selecting SLF4J with Logback/Log4j2, applying proper log levels (ERROR, WARN, INFO, DEBUG, TRACE), parameterized logging, secure logging without sensitive data exposure, environment-specific configuration, log aggregation and monitoring, or validating logging through tests.

Use when you need data access with Quarkus Hibernate ORM Panache — including PanacheEntity / PanacheEntityBase, PanacheRepository, named and HQL queries, DTO projections (project(Class)), pagination (Page.of()), N+1 avoidance (JOIN FETCH), optimistic locking (@Version / OptimisticLockException), @NamedQuery for validated reusable queries, transactions, @TestTransaction for test isolation, and immutable-friendly patterns. This is the Quarkus analogue to Spring Data for relational persistence. Part of the skills-for-java project
Search, order, and manage phone numbers by location, features, and coverage.
Collect DTMF input and speech from callers using standard gather or AI-powered gather. Build interactive voice menus and AI voice assistants. This skill provides JavaScript SDK examples.
