What is the PREFIX_CATEGORY_NUMBER format?

It is a naming convention (e.g., AUTH_VAL_001) that combines a service identifier, a functional category, and a unique number to make errors easily searchable and identifiable.

Can I use this for localized error messages?

Absolutely. The skill defines a structured message key format (error.prefix.category.number) that integrates seamlessly with i18n libraries like i18next or custom translation files.

Does this skill help with HTTP status code selection?

Yes, it provides a direct mapping guide between error categories (like VAL for Validation or BIZ for Business) and the most appropriate HTTP status codes (like 400 or 422).

How does the AI-optimized format help?

It provides a condensed YAML version of the error standards, allowing Claude to understand and apply your project's error rules while consuming fewer tokens during conversations.

API 개발

Implements consistent error code structures and HTTP mappings to improve debugging and API reliability.

This skill provides a comprehensive framework for designing and managing application error codes using the PREFIX_CATEGORY_NUMBER convention. It facilitates better debugging, monitoring, and user experiences by standardizing error categories—such as Validation, Business, System, and Auth—and mapping them to appropriate HTTP status codes. The skill includes support for internationalization (i18n), AI-optimized documentation formats to save tokens, and TypeScript implementation patterns to ensure consistency across modern software projects.
