SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate service implementations with business logic from specs and scaffold stubs. Use when implementing backend services.

Core Features & Use Cases

  • Generate per-endpoint service implementations with business logic from API contracts, scaffold stubs, and data models.
  • Provide shared helpers (error handling, pagination, transactions) and optional auth support.
  • Enable end-to-end generation of services with consistent patterns and testability.

Quick Start

Initiate the skill with relevant artifacts (backend-scaffold, backend-api-contract, backend-data-model) and review the generated service implementations.

FAQPage Schema
How do I generate backend service code from an API contract?

To generate backend service code from an API contract, you need to provide the API contract, data models, and scaffold stubs. The tool reads these inputs to automatically build per-endpoint service implementations complete with business logic and shared helpers.

Can I generate database transactions and idempotency logic for my endpoints?

Yes, you can generate database transactions and idempotency logic for your endpoints. The tool builds per-endpoint service code that explicitly includes optional support for auth, transactions, and idempotency alongside standard business logic.

What is the best way to implement consistent error handling and pagination across backend services?

The best way to implement consistent error handling and pagination is to generate service code from API contracts using automated scaffolding. This ensures robust, testable code patterns with shared helpers for pagination and errors are applied uniformly across all endpoints.

Does this backend code generation work with Prisma data models?

Yes, this backend code generation works with Prisma data models. It reads your data models and scaffold outputs to produce production-ready service implementations that integrate cleanly with your existing database schema and API contract specifications.

When do I need to provide scaffold stubs for backend service implementation?

You need to provide scaffold stubs for backend service implementation when you want to generate business logic from API contracts. Supplying the scaffold outputs, data models, and task breakdowns allows the generator to produce complete, testable per-endpoint service code.

How do I ensure my generated backend service code is clean and testable?

To ensure your generated backend service code is clean and testable, generate it from API contracts and scaffold stubs. The process enforces consistent patterns, robust error handling, and shared helpers, resulting in production-ready, testable implementations.
