nest

ACTIVATE when creating NestJS modules, controllers, services, guards, pipes, or configuring dependency injection. ACTIVATE for 'NestJS', '@Module', '@Controller', '@Injectable', 'guard', 'pipe', 'DI token'. Covers: module-per-bounded-context structure, thin controllers, ZodValidationPipe, guards for auth, exception filters, Symbol token-based DI for interfaces, constructor injection only. DO NOT use for: domain layer code (see nest-ddd-conventions), Zod schema design (see zod-conventions).

ACTIVATE when writing domain layer code in a NestJS project, defining ports/adapters, or structuring bounded contexts as NestJS modules. ACTIVATE for 'domain layer', 'DDD NestJS', 'port', 'adapter', 'bounded context', 'domain purity'. Covers: strict domain layer purity (no NestJS decorators, no ORM, no HTTP in domain), directory structure (domain/application/infrastructure), ports and adapters pattern with Symbol tokens, dependency direction rules. DO NOT use for: NestJS module/controller setup (see nest-conventions), general TypeScript DDD (see ddd-ts-fp).
