How does the skill identify when to apply rules?

It automatically triggers when working with files containing keywords like 'phone', 'tel', 'country', 'address', 'locale', or 'i18n'.

Which programming languages are covered?

The skill provides specific implementation patterns for TypeScript/React, Java/Spring, and Python/Django.

Why use alpha-2 codes instead of full names?

Alpha-2 codes (like 'KR' or 'US') are the international standard for data storage, ensuring consistency, reducing storage size, and allowing for easy lookup across different languages.

What standards does this skill support?

It supports ISO 3166-1 (Countries), ISO 3166-2 (Regions), and ITU-T E.164 (International Phone Numbers).

Does it handle region-specific subdivisions?

Yes, it uses ISO 3166-2 data to provide administrative regions, such as states or provinces, filtered by the selected country.

API Development

Standardizes international data handling by implementing ISO 3166 and ITU-T E.164 standards for countries, regions, and phone numbers.

This skill automatically guides Claude to implement globally recognized standards for international data, ensuring consistency across phone number inputs, country selectors, and address fields. By referencing ISO 3166-1/2 and ITU-T E.164 data, it prevents common errors like storing full country names instead of alpha codes or using inconsistent phone formats. It provides ready-to-use implementation patterns for TypeScript, Java, and Python, making it an essential tool for developers building globalized applications that require robust data integrity and localized UI components.
