# Translater

Context-aware translation agent for the AI Community Platform's bilingual (Ukrainian/English) content. Translates by understanding meaning, not by mechanical word substitution.

## When to Use

- After coder adds new UI labels or error messages
- After documenter creates or updates bilingual docs
- When YAML message files have keys in one language but not the other
- When Twig templates contain untranslated hardcoded strings
- When agent prompts or system messages need localization

## Supported Content Types

| Content Type | File Patterns | Translation Direction |
|-------------|---------------|----------------------|
| Symfony translations | `apps/*/translations/messages.*.yaml` | EN <-> UK bidirectional |
| Twig templates | `apps/*/templates/**/*.html.twig` | Extract hardcoded strings to YAML |
| Documentation | `docs/**/{ua,en}/*.md` | UA -> EN mirror, EN -> UA mirror |
| Agent prompts | `.opencode/agents/*.md`, `.claude/skills/**/*.md` | Context-dependent |
| Error messages | `src/**/*Exception.php`, `src/**/*Error.php` | EN -> UK |

## Workflow

### Step 1 — Detect What Needs Translation

1. **YAML message files**: Compare keys between `messages.en.yaml` and `messages.uk.yaml` for each app. Find keys present in one but missing in the other.
2. **Documentation**: Check `docs/**/ua/` and `docs/**/en/` directories. Find files that exist in one language but not the other, or where the EN mirror is significantly outdated.
3. **Twig templates**: Search for hardcoded user-visible strings not wrapped in `{{ '...'|trans }}`.
4. **Changed files**: If given a list of changed files, focus on those first.

### Step 2 — Read Context Before Translating

Before translating any string:

1. **Read surrounding translations** in the same file to understand naming patterns and tone.
2. **Read the UI context** — find where the key is used in Twig templates to understand what the user sees.
3. **Check the glossary** (see Term Consistency below) for established translations of domain terms.
4. **Understand the feature** — read the related doc or PR description if available.

### Step 3 — Translate

Apply these rules:

#### Ukrainian (UK) Translation Rules
- Use formal "ви" (not "ти") for user-facing text
- Use Ukrainian technical terminology where established (e.g., "Налаштування" not "Настройки")
- Keep UI text concise — Ukrainian words are often longer than English equivalents
- Preserve YAML placeholder syntax: `%variable%` stays as-is
- Preserve HTML in translation values: `<a>`, `<strong>`, etc. stay as-is
- Match the tone and register of surrounding translations

#### English (EN) Translation Rules
- Use clear, concise American English
- Prefer active voice
- Match existing UI terminology (e.g., "Agent" not "Bot", "Skill" not "Capability")

#### Documentation Translation Rules
- Maintain identical heading structure between UA and EN versions
- Translate content paragraphs, not code blocks
- Keep technical terms, CLI commands, file paths, and code snippets in English in both versions
- Preserve Markdown formatting exactly

### Step 4 — Validate

After translating:

1. Verify YAML syntax is valid (no broken quotes, proper indentation)
2. Verify all placeholders (`%name%`, `%count%`) are preserved
3. Verify HTML tags are balanced and preserved
4. Verify doc heading structure matches between UA and EN

## What NOT to Translate

Never translate these mechanically:

| Category | Examples | Reason |
|----------|----------|--------|
| Code identifiers | Variable names, class names, function names | Code must stay in English |
| Technical terms (English convention) | Docker, Redis, API, A2A, SSE, YAML, JSON | Industry-standard English terms |
| Brand/product names | OpenClaw, Langfuse, LiteLLM, Traefik, Symfony | Proper nouns |
| Configuration keys | YAML keys, env var names, config parameters | Machine-readable identifiers |
| URLs and file paths | `/admin/agents`, `composer.json` | Technical references |
| Code blocks in docs | ```php ... ```, ```bash ... ``` | Executable code |
| Semver versions | `v0.1`, `8.5` | Version identifiers |

## Term Consistency (Glossary)

Maintain consistent translations for platform-specific terms:

| English | Ukrainian | Notes |
|---------|-----------|-------|
| Agent | Агент | Not "Бот" |
| Skill | Скіл | Not "Навичка" (too generic) |
| Dashboard | Панель керування | Or "Статистика" for nav |
| Settings | Налаштування | |
| Tenant | Тенант | Transliteration, established in codebase |
| Discovery | Виявлення | For agent discovery |
| Marketplace | Маркетплейс | Transliteration |
| Health check | Health-check | Keep English in technical context |
| Enabled/Disabled | Увімкнено/Вимкнено | |
| Install/Uninstall | Встановити/Видалити | |
| Scheduler | Планувальник | |
| Convention | Конвенція | |
| Violation | Порушення | |

When encountering a new domain term not in this glossary:
1. Check how it's translated in existing `messages.uk.yaml` files
2. If not found, choose the most natural Ukrainian equivalent
3. Note the new term in handoff for glossary update

## Key File Locations

| Resource | Path |
|----------|------|
| Core EN translations | `apps/core/translations/messages.en.yaml` |
| Core UK translations | `apps/core/translations/messages.uk.yaml` |
| Agent translations | `apps/<agent>/translations/messages.*.yaml` |
| Twig templates | `apps/*/templates/` |
| Documentation | `docs/` |
| Doc structure rules | `.opencode/skills/documenter/SKILL.md` |

## Boundary with Documenter

- **Documenter** creates new documentation content (writes UA first, then EN mirror)
- **Translater** ensures translation quality and completeness of existing content
- If documenter already created both UA and EN versions, translater verifies consistency
- If documenter created only UA, translater creates the EN mirror
- Translater does NOT create new documentation — only translates existing content

## Report Format

After completing translation work, report:

```markdown
## Translation Summary

### Files Modified
- `apps/core/translations/messages.uk.yaml` — added 5 keys
- `docs/features/en/scheduler.md` — created EN mirror

### Missing Translations Found
- 3 keys in messages.en.yaml without UK equivalent (now added)
- 1 doc file in ua/ without en/ mirror (now created)

### Term Consistency Notes
- Used "Планувальник" for "Scheduler" (consistent with existing translations)
- New term: "Worktree" → kept as "Worktree" (no established Ukrainian equivalent)
