Discover the complete i18n setup. Returns project config (locales, default locale, layers, fallback chain, glossary, translation style) plus per-layer directory listings with file counts and top-level key namespaces. Call this first — it warms the config cache that all other tools depend on.

List the translation key tree grouped by namespace prefix. Returns a hierarchical view of all keys with counts per namespace node. Use this to explore available keys without guessing path prefixes.

Get translation values for given key paths from a specific locale and layer. Use "*" as locale to read from all locales.

Write translation key-value pairs to a layer. Mode "upsert" adds new keys and updates existing ones (default, most common). Mode "add" only creates new keys, skipping existing ones. Mode "update" only modifies existing keys, skipping missing ones. Keys are inserted in alphabetical order. Use dryRun to preview without writing.

Find translation keys that exist in the reference locale but are missing in other locales. Scans a specific layer or all layers.

Search translation files by key path or value. Simple case-insensitive substring match — not fuzzy or regex. Useful for finding existing translations before adding duplicates.

Remove one or more translation keys from ALL locale files in the specified layer. Use dryRun to preview changes before applying them.

Rename/move a translation key across ALL locale files in a layer. Preserves the value in every locale. Use dryRun to preview changes before applying them.

Find keys missing in target locales and translate them. Uses the host LLM via MCP sampling if available, otherwise returns context for the agent to translate inline. Uses project config (glossary, translation prompt, locale notes, examples) if available. Translates all locales concurrently by default — pass all targetLocales at once.

Add/update one source translation key and translate it into target locales. Unlike translate_missing, this can overwrite existing stale target translations.

Find translation keys that exist in locale JSON files but are not referenced in any Vue/TS source code. Scans a specific layer or all layers. Reports keys that can potentially be removed. Also detects dynamic key patterns and uncertain matches.

Find orphan keys (not referenced in source code) and remove them from all locale files. Always does a dry run first.

Create empty locale files for new languages. Copies the key structure from the default locale with all values set to empty strings. Supports both JSON (Nuxt) and PHP (Laravel) formats. Does NOT modify framework config — the agent must add the locale to the framework config before calling this tool.
