Api Patterns

Mcp Builder covers the core principles for creating Model Context Protocol servers that connect AI systems to external tools and data. It walks through server architecture, transport options, tool design patterns, resource management, and security practices you'll need to implement. The skill includes configuration guidance, testing strategies, and a practical checklist for production-ready MCP development.

Systematic Debugging guides you through a proven 4-phase process: reproduce the issue reliably, isolate its source, analyze root causes using techniques like the 5 Whys, and verify your fix works without introducing new problems. This skill prevents random troubleshooting and ensures you understand what's broken before attempting repairs.

Build APIs that developers love using. This skill covers RESTful conventions, proper HTTP method semantics, consistent error responses, pagination strategies, and versioning approaches. Learn how thoughtful naming, clear status codes, and predictable patterns make APIs intuitive and maintainable.

Select and implement the optimal API pattern for your backend needs. This skill guides you through REST, GraphQL, gRPC, and tRPC with framework recommendations for Python, TypeScript, Rust, and Go, plus pagination, caching, rate limiting, and OpenAPI documentation strategies.

Build APIs across REST, GraphQL, gRPC, and tRPC styles with contract-first design, RFC 9457 error models, and modern best practices. Covers OpenAPI specs, versioning strategies, authentication/authorization, rate limiting, pagination, and observability patterns for public and internal services.

This skill provides a structured framework for making architecture decisions through requirements analysis and trade-off evaluation. It guides you through context discovery, pattern selection, and ADR documentation with a core principle of starting simple and adding complexity only when necessary.
