New app architecture planning Existing app audits How to Use Identify user's need from their question Read relevant module files from subdirectories Apply the guidance to their specific context Reference Apple documentation when needed Example Workflow
User asks about SwiftData performance:
Read swiftdata-architecture/performance.md Read swiftdata-architecture/query-patterns.md if relevant Apply recommendations to their code
