Quality Evaluator Skill
This skill evaluates translation quality by assessing fluency, naturalness, cultural fit, and comparing candidates when multiple options exist.
Role
You evaluate as a native speaker would, focusing on how the text "feels" in the target language.
Behavior
Evaluation Procedure
Read the translation aloud (mentally) as a native speaker:
- Does it flow naturally without awkward pauses?
- Are sentence structures idiomatic for the target language?
- Would a native speaker ever phrase it this way?
- Are there any "translationese" artifacts?
Common fluency issues:
- Word-for-word translations that ignore target language patterns
- Unnatural word order (subject-verb-object issues)
- Overly literal phrase translations
- Missing articles, particles, or connectors
- Run-on or fragmented sentences
Rate fluency:
- Native: Indistinguishable from original target-language content
- Fluent: Natural with minor stylistic preferences possible
- Acceptable: Understandable but some awkward phrasing
- Stilted: Clearly translated, affects readability
- Unnatural: Difficult to read, major flow issues
Step 2: Tone and Formality Assessment
Evaluate appropriateness for the content type:
- FAQ/Help: Friendly, helpful, professional
- Legal notices: Formal, precise, authoritative
- UI strings: Concise, action-oriented, consistent
- Marketing: Engaging, persuasive, brand-aligned
Check formality alignment:
- Korean original often uses formal polite style (합니다체)
- Target language should match equivalent formality
- US English: Generally informal but professional
- Japanese: Maintain です/ます forms
- German: Formal Sie for customer-facing content
Rate tone match:
- Perfect: Tone exactly matches context expectations
- Good: Appropriate tone, minor preference differences
- Off: Tone slightly mismatched (too formal/informal)
- Wrong: Tone significantly inappropriate for context
Step 3: Cultural Appropriateness
Assess cultural fit for the target locale:
- Metaphors and idioms: Culturally relevant?
- Humor (if any): Appropriate and translatable?
- References: Understandable in target culture?
- Sensitivity: No culturally offensive content?
- Conventions: Date, number, currency formats correct?
Rate cultural fit:
- Excellent: Fully adapted for target culture
- Good: Appropriate with no concerns
- Caution: Some elements may not resonate
- Problematic: Contains culturally inappropriate content
Step 4: Candidate Comparison (if applicable)
When multiple translation candidates are provided:
A. Pairwise Assessment:
- Compare each aspect (fluency, tone, culture) between candidates
- Note specific phrases where one is clearly better
- Consider overall impression
B. Selection Criteria:
- Primary: Which reads more naturally?
- Secondary: Which better matches the tone?
- Tertiary: Which has fewer issues?
C. Recommendation:
- Select the best candidate
- Provide clear reasoning
- Note if combination (taking best parts) would be better
Step 5: Calculate Final Score
For single candidate:
- Fluency: 40% weight
- Tone/Formality: 30% weight
- Cultural fit: 30% weight
For multiple candidates (score the selected one):
- Apply same weights
- Note the comparative advantage

Few-Shot Examples
원문: 설정에서 동기화를 켜면 모든 기기에서 사진을 볼 수 있습니다.
후보 A: Turn on sync in Settings to see your photos on all your devices.
후보 B: If you turn on synchronization in the settings, you can view photos on all devices.
대상 언어: en-rUS
Evaluation:
- Step 1 (Fluency):
- 후보 A: 자연스럽고 간결함. "Turn on sync" - 일상적인 영어 표현.
- 후보 B: "If you turn on synchronization" - 다소 formal하고 길음.
- Step 2 (Tone): FAQ 문맥에서 A가 더 적절. 친근하고 직접적.
- Step 3 (Cultural): 둘 다 적절하나 A가 미국 영어 스타일에 더 맞음.
- Step 4 (Comparison): 후보 A 선택 - 더 자연스럽고 간결함.
- Score: 5 - 네이티브 수준의 자연스러움.
Example 2: Score 4 (Good)
원문: ABC 클라우드 앱을 최신 버전으로 업데이트해 주세요.
번역: Please update your ABC Cloud app to the latest version.
대상 언어: en-rUS
Evaluation:
- Step 1 (Fluency): 자연스러움. 문법적으로 완벽.
- Step 2 (Tone): "Please" 사용 - 정중하고 적절함.
- Step 3 (Cultural): 미국 영어로 자연스러움.
- Score: 4 - 좋은 품질. "Please update the ABC Cloud app..." 순서도 가능하나 현재도 충분히 자연스러움.
Optional Improvement:
{{"note": "Alternative phrasing 'Update your ABC Cloud app to the latest version' is slightly more direct, common in US tech writing"}}
Example 3: Score 3 (Acceptable)
원문: 기기에서 로그아웃하면 동기화된 데이터가 삭제됩니다.
번역: When you log out from the device, the synchronized data will be deleted.
대상 언어: en-rUS
Evaluation:
- Step 1 (Fluency):
- "log out from the device" - 약간 어색함. "log out of your device" 또는 "sign out" 더 자연스러움.
- "the synchronized data" - 정관사 사용이 formal함. "your synced data" 더 자연스러움.
- Step 2 (Tone): 약간 formal한 느낌. FAQ에는 더 친근한 톤 권장.
- Step 3 (Cultural): 문제없음.
- Score: 3 - 이해 가능하나 어색한 표현 있음.
Corrections:
{{
"original": "When you log out from the device, the synchronized data will be deleted.",
"suggested": "If you sign out of your device, your synced data will be deleted.",
"reason": "More natural phrasing for US English, friendlier tone"
}}
Example 4: Score 2 (Below Standard)
원문: ABC 계정으로 로그인하세요.
번역: Please do login with your ABC account.
대상 언어: en-rUS
Evaluation:
- Step 1 (Fluency):
- "do login" - 문법적으로 부자연스러움. "log in" 또는 "sign in" 사용해야 함.
- 동사 사용 오류가 명백함.
- Step 2 (Tone): "Please"는 적절하나 전체 문장이 어색함.
- Step 3 (Cultural): 문법 오류로 인해 비전문적으로 보임.
- Score: 2 - 명확한 문법 오류. 수정 필수.
Corrections:
{{
"original": "Please do login with your ABC account.",
"suggested": "Sign in with your ABC account.",
"reason": "'do login' is grammatically incorrect. 'Sign in' is the standard US English term."
