Internationalization (i18n) & localization (l10n) principles — locale-aware date, time, 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. 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, working with…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Internationalization & Localization Principles
i18n bugs are latent — they survive review unnoticed and only surface when the product expands to a new locale.
## Locale-Aware Formatting
*Use platform APIs that accept a locale tag; never hand-roll date or number rendering.*
- Use `Intl.DateTimeFormat(locale, options)` and `Intl.NumberFormat(locale, options)` — not `Date.toString()`, `toLocaleDateString()` without a locale argument, or manual template strings.
- Pass BCP 47 locale tags (`en-US`, `fr-FR`, `ar-EG`); rely on CLDR data in the runtime rather than custom format maps.
- Never hard-code `MM/DD/YYYY` — format order, separator, and calendar system (Gregorian vs. Hijri vs. Buddhist Era) vary by locale.
- Currency: let `Intl.NumberFormat(locale, { style: 'currency', currency: 'USD' })` place the symbol and decide sign position — never concatenate `"$" + amount`.
- For backend rendering, thread the `Accept-Language` header or a persisted locale preference down to the formatting layer.
## Time Zones: Persist UTC, Render Local
*Timestamps recorded in local time become ambiguous at DST boundaries and when users cross time zones.*

How to install
mdr add lugassawan/swe-workbench/principle-i18n@sha256:4c6ee7d77ffcd1efThe line at the top of this page pins the label git:20260828.71a6399, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
