What problem does it solve? Manual code reviews in .NET backends are inconsistent and often miss architectural violations like broken dependency rules, missing validators, or N+1 queries. This Skill provides a structured checklist so every review covers the same critical quality gates. ## Core Features & Use Cases - Clean Architecture Verification: Checks the Dependency Rule, domain isolation from external dependencies, and correct project references. - CQRS and EF Core Checks: Validates command/query separation, handler and validator implementation, explicit EF Core configurations, indexes, and N+1 query detection. - API and Test Coverage Review: Ensures thin controllers, Swagger annotations, consistent error handling, and unit/integration test coverage. - Use Case: Point the Skill at a feature folder in a .NET solution before opening a pull request to get a systematic review against all five checklist categories. ## Quick Start Ask the assistant to review a specific file or folder path in your .NET backend against the Clean Architecture checklist.
