backend-models
Define and configure database models with proper naming, relationships, timestamps, data types, constraints, and validation. Use this skill when creating or editing model files in app/Models/, Eloquent model classes, model relationships (hasMany, belongsTo, etc.), database table structures, model attributes and casts, model factories, or seeders. Use when working on model validation logic, database constraints, foreign key relationships, indexes, scopes, accessors, mutators, or any ORM-related model configuration.
Best use case
backend-models is best used when you need a repeatable AI agent workflow instead of a one-off prompt. It is especially useful for teams working in multi.

Practical example
Example input
Use the "backend-models" skill to help with this workflow task. Context: Define and configure database models with proper naming, relationships, timestamps, data types, constraints, and validation. Use this skill when creating or editing model files in app/Models/, Eloquent model classes, model relationships (hasMany, belongsTo, etc.), database table structures, model attributes and casts, model factories, or seeders. Use when working on model validation logic, database constraints, foreign key relationships, indexes, scopes, accessors, mutators, or any ORM-related model configuration.
Example output
A structured workflow result with clearer steps, more consistent formatting, and an output that is easier to reuse in the next run.
When to use this skill
- Use this skill when you want a reusable workflow rather than writing the same prompt again and again.
When not to use this skill
- Do not use this when you only need a one-off answer and do not need a reusable workflow.
- Do not use it if you cannot install or maintain the related files, repository context, or supporting tools.

# Backend Models This Skill provides Claude Code with specific guidance on how to adhere to coding standards as they relate to how it should handle backend models. ## When to use this skill - When creating or editing model files in `app/Models/` or similar model directories - When defining Eloquent model classes and their properties - When configuring model relationships (hasMany, belongsTo, belongsToMany, hasOne, morphTo, etc.) - When setting up model casts, fillable properties, or hidden attributes - When implementing model validation rules or business logic - When configuring database timestamps (created_at, updated_at) on models - When defining model scopes (query scopes, local scopes, global scopes) - When creating model factories for testing or seeding - When writing database seeders that use models - When implementing model accessors or mutators for attribute transformation - When setting up soft deletes or other model traits - When configuring model events or observers ## Instructions For details, refer to the information provided in this file: [backend models](../../../agent-os/standards/backend/models.md)
