Purpose

Configure and manage multilingual settings for the active brand. This command controls the language infrastructure that powers all translation, localization, and multilingual audit commands in the plugin. It sets the primary content language (the source language for all translations), secondary and target languages (which markets and languages the brand operates in), do-not-translate terms (brand names, product names, trademarked phrases, and technical terms that must appear identically in every language), preferred translation service per language (routing to the optimal MCP for each language pair), and locale-specific formatting rules (date, number, currency, measurement formats per market).

This configuration persists in the brand profile and is referenced by every multilingual command — translate, transcreate, multilingual-score, language-audit, hreflang-check, and any content creation targeting non-primary languages. Getting this configuration right upfront prevents repeated corrections downstream and ensures consistent multilingual output across all workflows.

Input Required

The user must provide (or will be prompted for):

• **Configuration action**: What to do — `view` (display all current language settings), `set-primary` (change the primary/source language), `add-language` (add a secondary/target language), `remove-language` (remove a secondary language), `add-dnt` (add a do-not-translate term), `remove-dnt` (remove a do-not-translate term), `set-translation-pref` (set preferred translation service for a language), `set-locale-format` (set locale-specific formatting for a language-region), or `reset` (restore language config to defaults)
• **Language code** (for language actions): ISO 639-1 language code with optional ISO 3166-1 region (e.g., `en`, `en-US`, `de-DE`, `hi-IN`, `ja-JP`, `pt-BR`). Required for set-primary, add-language, remove-language, set-translation-pref, and set-locale-format actions
• **Term** (for DNT actions): The exact term to add or remove from the do-not-translate list. Required for add-dnt and remove-dnt. Can be a single term or a comma-separated list of terms to add/remove in batch
• **Translation service** (for set-translation-pref): The preferred translation MCP server for the specified language — any server name the user has connected (free-form; validated as a non-empty slug). The preference is the user's explicit choice and outranks the router's capability-based selection. If the named server is not currently in `.mcp.json`, warn but still record it (the user may connect it later). Required for set-translation-pref action
• **Formatting preferences** (for set-locale-format): Locale-specific format settings — `date_format` (e.g., DD/MM/YYYY, MM/DD/YYYY, YYYY-MM-DD), `number_format` (decimal and thousands separators, e.g., "1,234.56" or "1.234,56"), `currency_format` (symbol position and spacing, e.g., "$1,234" or "1.234 EUR"), `measurement` (metric or imperial). Any subset can be provided; omitted fields retain current values

Process

1. **Load brand context**: Read `~/.claude-marketing/brands/_active-brand.json` for the active slug, then load `~/.claude-marketing/brands/{slug}/profile.json`. Apply brand voice, compliance rules for target markets (`skills/context-engine/compliance-rules.md`), and industry context. Also check for guidelines at `~/.claude-marketing/brands/{slug}/guidelines/_manifest.json` — if present, load restrictions. Check for agency SOPs at `~/.claude-marketing/sops/`. If no brand exists, ask: "Set up a brand first (/digital-marketing-pro:brand-setup)?" — or proceed with defaults. 2. **Read current language configuration**: Extract the `language` object from `profile.json` containing `primary_language`, `secondary_languages`, `content_languages`, `do_not_translate`, `translation_preferences`, and `locale_formatting`. If the language object does not exist yet (new brand or pre-multilingual setup), initialize it with sensible defaults: primary_language set to "en", empty arrays for secondary_languages and do_not_translate, and empty objects for translation_preferences and locale_formatting. 3. **For view action**: Display all current language settings in a clear, structured format — primary language with full name (e.g., "en-US: English (United States)"), all secondary languages with full names, the complete do-not-translate term list, translation service preferences per language (showing which MCP handles each), locale formatting rules per language-region, and a summary of which translation services are configured versus using auto-routing defaults. 4. **For set-primary action**: Validate the provided language code against ISO 639-1 (and ISO 3166-1 if region included). Check that the language is supported by at least one configured translation MCP via `language-router.py --action supported-languages`. Update `profile.json` field `language.primary_language` to the new value. If the old primary language is not already in secondary_languages and the user has content in it, suggest adding it as a secondary language to maintain existing translations. 5. **For add-language / remove-language actions**: Validate the language code. For add: append to both `language.secondary_languages` and `language.content_languages` arrays (avoiding duplicates). Run `language-router.py --action route --source en --target {code} --brand {slug}` and present
