Use this skill when the task is about message authoring, translation consumption, or locale-aware formatting behavior.

Scope

• message catalog structure and namespace strategy
• ICU authoring patterns
• useTranslations, t.rich, t.markup, t.raw, t.has
• useFormatter and named formats
• typed ICU arguments and message validation
• useExtracted as an optional workflow

Routing cues

• message JSON structure, namespace design, ICU, rich text, formatting, validation -> use this skill
• defineRouting, locale switchers, domains, pathnames -> use next-intl-routing-and-navigation
• getTranslations in metadata, setRequestLocale, testing, error files -> use next-intl-server-runtime
• plugin flags, TypeScript augmentation, Crowdin, loading strategy -> use next-intl-workflows-and-tooling
