Backend Models

关于

Empowers Claude to design robust and well-structured backend architectures by adhering to strict database modeling standards. This skill guides the creation of ORM model classes and entities with proper naming conventions, precise data types, and essential constraints such as foreign keys and unique indexes. It ensures that complex relationships—ranging from basic associations to polymorphic links—are implemented correctly while maintaining data integrity through model-level validations and automated timestamps.
