backend-models

Define and structure database models with proper naming conventions, data integrity constraints, and relationship definitions. Use this skill when creating or modifying database model files, defining table schemas, setting up model relationships (one-to-many, many-to-many, one-to-one), working with ORM model files (schema.prisma, models/*, app/models/*, entities/*), implementing data validation at the model level, adding timestamps and audit fields, defining foreign keys and indexes, choosing appropriate data types, configuring cascade behaviors, or balancing database normalization with query performance. Apply this skill when designing database schemas, creating new models, refactoring existing model structures, or reviewing data integrity and relationship configurations.

description: Define and structure database models with proper naming conventions, data integrity constraints, and relationship definitions. Use this skill when creating or modifying database model files, defining table schemas, setting up model relationships (one-to-many, many-to-many, one-to-one), working with ORM model files (schema.prisma, models/*, app/models/*, entities/*), implementing data validation at the model level, adding timestamps and audit fields, defining foreign keys and indexes, choosing appropriate data types, configuring cascade behaviors, or balancing database normalization with query performance.

# Backend Models ## When to use this skill - When creating or modifying database model files (e.g., `schema.prisma`, `models/*`, `app/models/*`, `entities/*`) - When defining table schemas and column data types - When setting up model relationships (one-to-many, many-to-many, one-to-one) - When adding database constraints (NOT NULL, UNIQUE, foreign keys, check constraints) - When implementing timestamps (createdAt, updatedAt) and audit fields - When choosing appropriate data types for columns based on data requirements - When adding indexes on foreign keys and frequently queried fields - When defining validation rules at the model or database level - When configuring cascade behaviors for relationships (CASCADE, SET NULL, RESTRICT) - When balancing database normalization with practical query performance needs - When naming models following singular/plural conventions - When reviewing data integrity and relationship definitions 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. ## Instructions For details, refer to the information provided in this file: [backend models](../../../agent-os/standards/backend/models.md)

backend-api

Design and implement RESTful API endpoints following REST principles with clear resource-based URLs and appropriate HTTP methods. Use this skill when creating API routes, defining API endpoints, implementing HTTP request handlers, working on route files (routes.ts, route.ts, api/*, controllers/*, handlers/*), building REST APIs, designing API versioning strategies, setting up query parameters for filtering and pagination, implementing rate limiting, or returning appropriate HTTP status codes. Apply this skill when structuring backend API architecture, creating new API endpoints, refactoring existing endpoints, or reviewing API design for consistency and best practices.

backend-migrations

Create and manage database migrations following best practices for schema changes and data migrations. Use this skill when creating database migration files, modifying database schemas, adding or removing tables and columns, working with migration files (prisma/migrations/*, db/migrate/*, migrations/*), implementing reversible migrations with rollback methods, managing database indexes, handling zero-downtime deployments, separating schema changes from data migrations, or ensuring backwards compatibility during schema updates. Apply this skill when setting up new database tables, altering existing database structures, creating migration scripts, or reviewing migration safety and rollback strategies.

backend-queries

Write optimized and secure database queries using parameterized queries, eager loading, and proper indexing strategies. Use this skill when writing database queries, constructing SQL statements, using ORM query methods, implementing data fetching logic, preventing SQL injection attacks, optimizing query performance, avoiding N+1 query problems, selecting specific columns instead of all data, implementing transactions for related operations, setting query timeouts, caching expensive queries, or working with WHERE clauses, JOINs, and ORDER BY statements. Apply this skill when fetching data from databases, optimizing slow queries, refactoring data access code, or reviewing query security and performance.
