Guidance on designing consistent, developer-friendly REST APIs, covering resource naming, HTTP methods, status codes, pagination, filtering, error envelopes, and versioning for public or partner-focused services.

Guidance on designing consistent, developer-friendly REST APIs, covering resource naming, HTTP methods, status codes, pagination, filtering, error envelopes, and versioning for public or partner-focused services.

Guides REST API teams on naming resources, versioning, pagination, OpenAPI specs, error handling, headers, and rate limiting to keep services consistent, scalable, and client-friendly.

Mastering the principles of REST and GraphQL is crucial for building modern, scalable, and developer-friendly APIs. This skill guides you through defining robust API contracts, covering topics like versioning, pagination, error handling, and authentication strategies. Use it when designing new microservices, refactoring legacy APIs, or setting architectural standards for your team.

A comprehensive guide covering crucial API architectural decisions and best practices. Learn when to choose between REST, GraphQL, and tRPC, define robust response formats, implement versioning strategies, and secure endpoints using OAuth or JWT. This skill helps developers build scalable, maintainable, and secure backend services.

This skill provides comprehensive guidance on mastering proven backend architectural patterns, including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design (DDD). It helps users design, refactor, and scale complex systems by defining clear module boundaries, managing dependencies, and ensuring testability. Use it when migrating monolithic applications, initiating microservices decomposition, or establishing robust architectural standards.

Provides industry-standard patterns and modern best practices for building secure, scalable authentication and authorization systems. This guide helps developers implement complex identity management features, such as OAuth2, OpenID Connect (OIDC), JWT validation, session management, and Role-Based Access Control (RBAC), ensuring APIs and services adhere to the highest security standards.

This skill defines mandatory architectural standards and best practices for developing robust, scalable, and observable backend services using Node.js, Express, and TypeScript. It mandates layered architecture (Routes → Controllers → Services → Repositories), strong error handling, dependency injection, and input validation (Zod) to ensure maintainability and reliability in production environments. Use when designing or refactoring core API logic.

Design and deploy an API gateway that unifies routing, load balancing, auth enforcement, rate limiting, transformations, and aggregation across multiple services, providing centralized observability and resilience patterns for microservice architectures.

Provides reference architecture patterns for implementing Clerk authentication across Next.js, microservices, multi-tenant SaaS, and mobile+web stacks, guiding designers through auth flow planning, component diagrames, and integrations.
