Implements internationalization frameworks and localization best practices to prepare applications for global markets and multi-language support.

This skill equips Claude with the domain-specific knowledge required to architect and implement robust internationalization (i18n) and localization (L10n) systems across diverse tech stacks. It provides specific implementation patterns for popular frameworks like React, Next.js, and Python, ensuring that applications handle locale-specific formatting, pluralization, and Right-to-Left (RTL) layouts correctly. By guiding developers through standardized file structures and providing scripts to detect hardcoded strings, this skill helps prevent common globalization errors such as string concatenation, layout breakage in expanded languages, and missing translation keys.
