enable-i18n
Enable i18n (next-intl, no Markets)
Add next-intl so the storefront serves locale-prefixed URLs (/en-US/products/foo), loads per-locale message catalogs, and exposes a copy-language switcher. The default is one deployment with clean URLs, inline component copy with reusable functions in lib/content/index.ts, and shopConfig.localization = { country: "US", language: "EN", locale: "en-US" }. There is no next-intl dependency, message catalog, lib/i18n/ directory, or lib/params/server.ts locale resolver to reuse in a fresh template.
Use
enable-shopify-marketsinstead for regional commerce. This skill translates storefront copy and adds routing; it must not infer a commerce country from a copy locale or mutate cart buyer country when language changes. Keep Shopify country/language configuration explicit, preserve intentional operation locale/cache inputs, and always display currency from Shopify responses.
Inspect and preserve the installation
Read scoped AGENTS.md, package.json, next.config.ts, lib/config/index.ts, lib/content/index.ts, routes, components, layout, proxy, and any existing localization files. Trace copy consumers, formatting, SEO, markdown, cart, auth, and chat boundaries before editing.
Choose the migration path from evidence:
- Fresh simplified template: introduce next-intl, catalogs, request config, routing, and the locale resolver using the steps below.
- Already localized or customized: preserve its next-intl version/configuration, catalogs, translations, rich text, providers, supported locales, domains, prefixes, locale cookies, redirects, and commerce behavior. Fill only missing pieces. Do not replace existing catalogs with template English, move routes twice, or reset the locale list to these examples. If the requested routing conflicts with existing public URLs, obtain a migration decision before changing them.
- Mixed migration: inventory inline copy, content functions, and catalogs. Convert only unmigrated consumers and retain modules still in use. Do not delete working translations or collapse locale-sensitive commerce/cache arguments.
Confirm the default copy locale and supported copy locales with the user. In a noninteractive run, report any unresolved choice and stop rather than choosing a routing or translation policy.
