Can it localize technical error messages?

Yes, it specifically enforces a guardrail to map raw error codes to localized keys, ensuring users see friendly messages while logs retain technical details.

How does the skill handle missing translations?

The skill includes an audit workflow that identifies missing keys and parity gaps between locale files, treating them as blockers to ensure a complete user experience.

Does it support Right-to-Left (RTL) languages?

Yes, if RTL locales are within the project scope, the skill provides guidance on using logical CSS properties and testing layout adjustments.

Does this skill translate content automatically?

It facilitates the translation strategy by extracting keys and can generate translations via AI, while also supporting professional or manual translation workflows.

Which i18n frameworks does this skill support?

It supports major web frameworks including React (react-i18next), Next.js (next-intl), and Vue (vue-i18n), as well as general JSON-based locale structures.

Developer Tools

Automates internationalization workflows by configuring i18n frameworks, extracting UI strings, and ensuring locale parity across codebases.

About

The Internationalization Expert skill streamlines the entire localization lifecycle for modern web applications. It handles initial i18n framework configuration, systematically replaces hard-coded strings with translation keys, ensures parity across locale files—specifically focusing on en-US and zh-CN—and validates complex formatting rules like pluralization and date/time. By auditing UI codebases and mapping error codes to localized messages, it helps developers build globally accessible products with consistent, production-ready translation structures.
