Localization & Internationalization (i18n)

Internationalization (i18n) is the process of designing software so it can be adapted to different languages and regions without engineering changes. Localization (l10n) is the actual adaptation - translating strings, formatting dates and currencies, supporting right-to-left scripts, and handling pluralization rules that vary wildly across languages. This skill gives an agent the knowledge to set up i18n infrastructure, write correct ICU MessageFormat patterns, handle RTL layouts, manage translation workflows, and avoid the common traps that cause garbled UIs in non-English locales.
