Backend Models

定义并组织数据库模型和实体，采用恰当的命名规范、时间戳、数据完整性约束、关系和验证层。在创建或修改ORM模型定义、数据库实体类、模式定义或数据访问层对象时使用此技能。在处理TypeORM实体、Sequelize模型、SQLAlchemy模型、Mongoose模式、Django模型、Prisma模式文件或任何框架特定模型文件（models.ts、entities.py、schema.prisma、models.py）时使用。在定义表结构、外键关系、数据库约束（NOT NULL、UNIQUE）、索引或多层验证规则时使用。在实施仓储模式或设计平衡规范化与查询性能的数据模型时使用。

name: Backend Models
description: Define and structure database models and entities with proper naming conventions, timestamps, data integrity constraints, relationships, and validation layers. Use this skill when creating or modifying ORM model definitions, database entity classes, schema definitions, or data access layer objects. Use when working with TypeORM entities, Sequelize models, SQLAlchemy models, Mongoose schemas, Django models, Prisma schema files, or any framework-specific model files (models.ts, entities.py, schema.prisma, models.py). Use when defining table structures, foreign key relationships, database constraints (NOT NULL, UNIQUE), indexes, or multi-layer validation rules. Use when implementing repository patterns or designing data models that balance normalization with query performance.

Backend Models

This Skill provides Claude Code with specific guidance on how to adhere to coding standards for database models and entity design.

When to use this skill

  • •When creating or modifying ORM model/entity definition files
  • •When working with model files (models.ts, entities.py, schema.prisma, models.py, models.rb, etc.)
  • •When defining database table structures and column properties
  • •When setting up relationships between models (one-to-many, many-to-many, etc.)
  • •When implementing database constraints (NOT NULL, UNIQUE, foreign keys)
  • •When adding timestamps (createdAt, updatedAt) to models
  • •When choosing appropriate data types for model fields
  • •When creating indexes on frequently queried columns
  • •When implementing validation at the model layer
  • •When designing repository patterns for data access
  • •When balancing database normalization with query performance needs
  • •When defining cascade behaviors for related entities
