Apply SOLID principles and design patterns to backend code with judgment and restraint. Use this skill whenever the user asks to refactor, review, clean up, restructure, or improve the design of backend code (services, APIs, domain logic, data access, handlers, jobs) — or mentions SOLID, design patterns, coupling, separation of concerns, testability, or "this code is hard to change/test." Also use when generating new backend modules that should be well-structured. Works in any backend language (Python, TypeScript/Node, Java, Go, C#, etc.). It scopes changes to specified parts of the codebase and reads a configurable rigor level so the depth of refactoring matches what the user wants.
