Use when writing, fixing, or editing TypeScript data models, DTOs, discriminated unions, classes, object boundaries, optional fields, null or undefined absence, repeated conditionals, impossible states, or object-chain access.
Use when building NestJS applications requiring modular architecture, dependency injection, or TypeScript backend development. Invoke for modules, controllers, services, DTOs, guards, interceptors, TypeORM/Prisma.
Use when you need to design, review, or improve REST APIs with Micronaut — including @Controller routes, HTTP status codes, DTOs, Bean Validation, exception handlers, pagination, idempotency, ETag/If-Match, caching headers, versioning, OpenAPI, and security annotations. Part of the skills-for-java project
Data Transfer Objects using Spatie Laravel Data. Use when handling data transfer, API requests/responses, or when user mentions DTOs, data objects, Spatie Data, formatters, transformers, or structured data handling.
Provide repeatable CRUD workflows for Spring Boot 3 services with Spring Data JPA and feature-focused architecture; apply when modeling aggregates, repositories, controllers, and DTOs for REST APIs.
Unit tests for mappers and converters (MapStruct, custom mappers). Test object transformation logic in isolation. Use when ensuring correct data transformation between DTOs and domain objects.
Use when Java XML-RPC API work requires contract decisions for fault signaling and interoperability, including defining XmlRpcException-based failures, replacing void returns with explicit operation results, reviewing handlers for return-code anti-patterns, and migrating DTOs from Serializable to JAXB.
API contract audit worker (L3). Checks layer leakage in method signatures, missing DTOs, entity leakage to API, inconsistent error contracts, redundant method overloads. Returns findings with 4-score model (compliance, completeness, quality, implementation).
Generates complete CRUD modules for NestJS applications with Drizzle ORM. Use when building server-side features in NestJS that require database operations, including creating new entities with full CRUD endpoints, services with Drizzle queries, Zod-validated DTOs, and unit tests. Triggered by requests like "generate a user module", "create a product CRUD", "add a new entity with endpoints", or when setting up database-backed features in NestJS.
Provides comprehensive NestJS best practices including modular architecture, dependency injection scoping, exception filters, DTO validation with class-validator, and Drizzle ORM integration. Use when designing NestJS modules, implementing providers, creating exception filters, validating DTOs, or integrating Drizzle ORM within NestJS applications.
Build production-grade Laravel REST APIs using opinionated architecture patterns with Laravel best practices. Use when building, scaffoling, or reviewing Laravel APIs with specifications for stateless design, versioned endpoints, invokable controllers, Form Request DTOs, Action classes, JWT authentication, and PSR-12 code quality standards. Triggers on "build a Laravel API", "create Laravel endpoints", "add API authentication", "review Laravel API code", "refactor Laravel API", or "improve Laravel code quality".
Generate Chi HTTP handlers following GO modular architechture conventions (request/response DTOs, use case orchestration, error handling, swagger annotations, Fx DI). Use when creating HTTP endpoint handlers in internal/modules/<module>/http/chi/handler/ for REST operations (List, Create, Update, Delete, Get) that need to decode requests, call use cases, map responses, and handle errors with proper logging and tracing.
