A translation guide for localising Roo Code extension and web-interface text into the project's supported languages.

In plain words
What is it for?
Use it when adding languages, translating strings, or updating existing translations in Roo Code.
Why use it?
It explains where translation files live and how to keep new or changed interface text consistent across languages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

roo-translation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Roo Code Translation Skill

When to Use This Skill

Use this skill when the task involves:

  • Adding new translatable strings to the Roo Code extension
  • Translating existing strings to new languages
  • Updating or fixing translations in existing language files
  • Understanding i18n patterns used in the codebase
  • Working with localization files in either core extension or WebView UI

When NOT to Use This Skill

Do NOT use this skill when:

  • Working on non-translation code changes
  • The task doesn't involve i18n or localization
  • You're only reading translation files for reference without modifying them

Supported Languages and Locations

Localize all strings into the following locale files: ca, de, en, es, fr, hi, id, it, ja, ko, nl, pl, pt-BR, ru, tr, vi, zh-CN, zh-TW

The VSCode extension has two main areas that require localization:

Component Path Purpose
Core Extension src/i18n/locales/ Extension backend strings
WebView UI webview-ui/src/i18n/locales/ User interface strings

Brand Voice, Tone, and Word Choice

For detailed brand voice, tone, and word choice guidance, refer to the guidance file:

This guidance file is loaded at runtime and should be consulted for the latest brand and style standards.

Voice, Style and Tone Guidelines

  • Always use informal speech (e.g., "du" instead of "Sie" in German) for all translations
  • Maintain a direct and concise style that mirrors the tone of the original text
  • Carefully account for colloquialisms and idiomatic expressions in both source and target languages
  • Aim for culturally relevant and meaningful translations rather than literal translations
  • Preserve the personality and voice of the original content
  • Use natural-sounding language that feels native to speakers of the target language

Terms to Keep in English

  • Don't translate the word "token" as it means something specific in English that all languages will understand
  • Don't translate domain-specific words (especially technical terms like "Prompt") that are commonly used in English in the target language

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
