+### Guardian Package Architecture
+
+The guardian package follows Clean Architecture principles:
+- **Domain Layer**: Core business logic (entities, value objects, domain events)
+- **Application Layer**: Use cases, DTOs, and mappers
+- **Infrastructure Layer**: External concerns (parsers, analyzers, file scanners)
+- **CLI Layer**: Command-line interface implementation
+
+Key features:
+- Hardcode detection (magic numbers, strings)
+- Circular dependency detection
+- Naming convention validation
+- CLI tool with `guardian` command
+
