Skill Claude CodeCodex
Use this skill when implementing database persistence, choosing a data source pattern, managing repository interfaces, writing mappers, or splitting large repositories. Assumes the decision between a rich domain model and a lean ORM model has already been made by the domain-modeling skill.
Skill Claude CodeCodex
Use this skill when writing tests for a PHP application. Provides layer-specific guidance to choose the right testing style (unit, integration, feature) for domain objects, mappers, repositories, handlers, and controllers.
