SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you design and implement backend systems that are correct, secure, testable, and maintainable—covering API contracts, database schemas, error handling, performance, and reliability.

Core Features & Use Cases

  • Architecture-first design: Reviews key decisions (caching, consistency, communication patterns, data ownership) with options, trade-offs, and a recommended path.
  • API and contract rigor: Produces REST/gRPC/event-driven API designs with status codes, error shapes (RFC 9457), pagination, and versioning guidance.
  • Database and data-model discipline: Guides schema normalization, key strategy (UUID v7/ULID), indexing for query paths, and zero-downtime migrations.
  • Safety and operational guardrails: Enforces deterministic steps like test-first behavior, asks for confirmation before writing/running anything, and includes observability/security/testing practices.
  • Security and reliability patterns: Covers OAuth/JWT validation checklists, idempotency for messaging, rate limiting, and failure-mode thinking.

Quick Start

Use the backend-engineer skill to design a REST API endpoint for creating and validating a new resource, including the database schema, error responses, and the exact test plan required to implement it safely.

Frequently Asked Questions about backend-engineer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design a REST API with proper error handling and status codes?▼

Designing a REST API with proper error handling involves defining endpoints with standard status codes and RFC 9457 error shapes. This approach ensures API contracts include pagination, versioning guidance, and structured error responses for maintainability.

What is the best way to plan zero-downtime database schema migrations?▼

Planning zero-downtime database schema migrations requires guiding schema normalization and indexing for query paths. Using deterministic key strategies like UUID v7 or ULID ensures safe data ownership and migration without service interruption.

How do I implement authentication and JWT validation for microservices?▼

Implementing authentication and JWT validation for microservices requires applying OAuth and JWT validation checklists. This enforces security patterns including rate limiting, idempotency for messaging, and failure-mode thinking across the service architecture.

Does this approach support event-driven architecture and gRPC systems?▼

Yes, this approach supports event-driven architecture and gRPC systems by designing and implementing backend APIs for server-side logic. It accommodates communication patterns, caching, and consistency trade-offs specific to event-driven systems.

How do I structure test-first behavior for backend API endpoints?▼

Structuring test-first behavior for backend API endpoints requires generating an exact test plan before implementation. This operational guardrail enforces deterministic steps, asking for confirmation before executing any file, command, or database actions.
