Validate REST API standards compliance (versioning, naming, HTTP methods, status codes, pagination, Swagger). Use when checking endpoints before deployment, reviewing API design, or ensuring documentation completeness (e.g., "Validate User API", "Check Product endpoints").
Setup ESLint with Airbnb TypeScript config and Prettier formatter for code quality enforcement. Use when setting up new project, adding linting/formatting, or configuring code quality tools (e.g., "Setup ESLint and Prettier", "Configure code quality", "Add Airbnb linter").
Generate REST API endpoints with class-validator DTOs, routing-controllers decorators, and complete Swagger docs. Use when creating API endpoints for existing use cases, adding routes, or building custom API actions (e.g., "Create user API", "Generate product endpoints").
Generate complete DDD bounded context with all 4 layers (Domain, Application, Infrastructure, Presentation). Use when user wants to create new business capability, scaffold complete context with CRUD, or build full feature from scratch (e.g., "Create Order context", "Generate Product context with inventory").
Generate domain layer components (entities, value objects, repository interfaces, events, errors). Use when adding entities to existing context, creating value objects for validation, or defining domain-specific errors (e.g., "Create Product entity with Price VO", "Add Customer with Email").
Generate application layer use cases and event listeners with proper DI and orchestration. Use when adding business operations, creating workflows, or implementing event-driven logic (e.g., "Create RegisterUser use case", "Generate PlaceOrder with inventory check").
Validate DDD architecture compliance including layer separation, dependency rules, and patterns. Use when validating context before commit, checking new features, reviewing refactored code, or ensuring layer isolation (e.g., "Validate User context", "Check Product domain layer").
Manage tsyringe DI container registration, scan injectable classes, detect missing registrations, validate injection patterns, and generate registration code. Use when registering repositories, fixing DI errors, or setting up new context (e.g., "Register ProductRepository", "Check DI setup").
