+name: i18n-pass
+description: Convert hard-coded English text in changed Vue components to the @modrinth/ui localization system. Use for an i18n pass, untranslated-string review, pull request, or component migration.
+---
+
+# Do an Internationalization Pass
+
+Read the applicable `AGENTS.md` files before you edit code.
+
+Read [the internationalization standard](../../../standards/frontend/INTERNATIONALIZATION.md) in full.
+
+1. Identify the scope from the request.
+2. For a pull request, use `gh pr diff <number>` to identify changed files.
+3. For a file path, inspect that file.
+4. When the request gives no scope, inspect the current uncommitted diff.
+5. Limit the pass to changed `.vue` files.
+6. Find user-visible text in templates and scripts.
+
+Check inner text, `alt`, `placeholder`, `aria-label`, buttons, tooltips, notifications, dropdown labels, and error messages.
+
+Do not change dynamic expressions, HTML tag names, CSS classes, internal identifiers, or log messages.
+
+1. Define stable message IDs with `defineMessage` or `defineMessages`.
+2. Replace simple text with `formatMessage()` calls.
+3. Use `<IntlFormatted>` for text that contains links or markup.
+4. Use ICU selections and plurals when grammar depends on a value.
+5. Add a space before `}}` when an ICU placeholder ends at the Vue delimiter.
+6. Do not change component logic, layout, or reactivity.
+7. Do not edit localization JSON files. The user maintains those files.
+8. Check the changed templates again for hard-coded English text.
+
+Run only the checks that the user or the applicable `AGENTS.md` permits.
