This Skill enables teams to extend the domain error surface by introducing custom errors that integrate with the existing BaseError hierarchy and automatic HTTP status mapping, reducing boilerplate and improving consistency.
Create a new error class extending BaseError, implement it in your service layer, and throw it when a business rule is violated.

Yes, you can standardize error handling across backend controllers, services, and repositories by extending a BaseError class. This approach provides clear, actionable error messages and maps errorCodes to HTTP statuses for consistent business-rule validation.
You can implement domain-specific errors by creating a class that extends BaseError and throwing it when a business rule is violated. This integrates your custom error types directly into the service layer for structured error handling.
This approach applies to backend services that need structured error handling. It relies on extending an existing BaseError hierarchy to integrate new domain-specific errors, but requires no additional external dependencies.
Extending a BaseError hierarchy enables automatic HTTP status mapping and reusable error types across your domain. This improves consistency and provides clear, actionable error messages compared to throwing generic errors.
Yes, you can apply business-rule validation across controllers and services by throwing custom error classes that extend BaseError. This ensures structured error handling with clear, actionable messages when rules are violated.
