What is the difference between i18n and l10n in this skill?

Internationalization (i18n) focuses on engineering the application to support multiple regions without code changes, while Localization (l10n) involves the actual adaptation of the app for a specific locale, such as translating text and formatting currencies.

Can this skill detect hardcoded strings in my code?

Yes, the localization-testing skill is designed to scan your source code for user-facing strings that haven't been externalized, helping you maintain a clean translation workflow.

How does it handle complex character sets like Kanji or Emojis?

The skill includes Unicode character support testing to verify that your database and frontend correctly handle, store, and display non-Latin scripts and special characters.

Does it support Right-to-Left (RTL) languages like Arabic or Hebrew?

Absolutely. It includes specific checks for RTL layout flipping, CSS direction attributes, and ensuring that icons like back arrows are mirrored correctly for RTL users.

Security & Testing

Automates internationalization and localization testing to ensure global products function correctly across different languages, regions, and cultural formats.

The Localization Testing skill empowers Claude to validate multi-language support by auditing translation coverage, verifying locale-specific formats for dates and currencies, and ensuring UI integrity for Right-to-Left (RTL) languages. Built on the Agentic QE framework, it leverages specialized agents to detect hardcoded strings and perform visual regressions, helping development teams launch into new markets with confidence that their user experience is culturally appropriate and technically sound.
