Guides agents in implementing backend services and APIs, including transport layers, business logic, database access, integrations, event handling, coexistence seams, error handling, and service-level testing.
Design and implement backend services and APIs — REST, gRPC, GraphQL, event-driven handlers, transaction boundaries, outbox/inbox delivery, migration coexistence, database access, integration, error handling, and service-level testing. Use for application/domain/infrastructure implementation decisions. Language and framework agnostic. Do not use for frontend, data engineering, platform provisioning, API contract ownership, service decomposition strategy, or cross-system migration planning.
