Principle I18n

Category: Content  ·  Sub-category: translation  ·  Last updated:
Internationalization (i18n) & localization (l10n) principles — locale-aware date, time, number, and currency formatting, time-zone correctness (persist UTC in DB, render local), CLDR plural rules, message catalogs (ICU MessageFormat, gettext), translatable string composition (no concatenation), bidirectional & right-to-left layout, character-encoding hygiene, sortable date formats (ISO 8601). Auto-load when adding a new locale, formatting dates/times/numbers/currency for display, persisting timestamps, building message catalogs, composing user-facing strings from variables, designing pluralized copy, working with right-to-left scripts, choosing between backend and frontend locale negotiation, or auditing existing UI strings for translation readiness.

From the source SKILL.md

i18n bugs are latent — they survive review unnoticed and only surface when the product expands to a new locale.
