# YouTube Automation Pipeline Prompt Design

## 목적
이 문서는 YouTube 자동화 파이프라인의 각 단계에서 바로 사용할 수 있는 **실전형 핵심 프롬프트 초안**을 정리한 것이다.

중요 원칙:
- 특정 언어나 특정 장르에 고정되지 않는다.
- 모든 프롬프트는 `{{LANGUAGE}}`, `{{CONTENT_TYPE}}`, `{{TARGET_AUDIENCE}}` 등 플레이스홀더를 사용해 범용적으로 동작해야 한다.
- 역사, 경제, 과학, 다큐, 썰, 에세이, 리뷰, 명상, ASMR 등 다양한 카테고리에 적용 가능해야 한다.
- 예시는 이해를 돕기 위한 참고일 뿐, 구조 자체는 일반화되어야 한다.

---

## 공통 플레이스홀더 규격
아래 플레이스홀더는 전체 파이프라인에서 공통적으로 재사용한다.

- `{{LANGUAGE}}`: 최종 출력 언어
- `{{CONTENT_TYPE}}`: 콘텐츠 유형 (예: documentary, explainer, commentary, listicle, story, meditation, ASMR, educational)
- `{{TOPIC}}`: 이번 영상의 핵심 주제
- `{{TARGET_AUDIENCE}}`: 타겟 시청자
- `{{TARGET_DURATION}}`: 목표 러닝타임
- `{{PLATFORM}}`: 기본값 YouTube
- `{{CHANNEL_POSITIONING}}`: 채널 포지셔닝
- `{{TONE}}`: 전달 톤 (예: cinematic, analytical, warm, provocative, calm)
- `{{NARRATIVE_STYLE}}`: 서사 방식 (예: mystery-driven, curiosity loop, chronological, problem-solution, emotional reveal)
- `{{KEYWORD_SET}}`: SEO 핵심 키워드
- `{{FACT_SENSITIVITY}}`: 팩트 정확도 요구 수준 (low / medium / high / critical)
- `{{VISUAL_STYLE}}`: 이미지/영상의 비주얼 방향
- `{{MONETIZATION_OR_CTA_GOAL}}`: 구독, 댓글, 클릭, 세일즈, 리드 확보 등

## 설계 원칙 요약
웹 조사 및 실전 YouTube 스크립트 패턴에서 반복적으로 확인되는 핵심은 다음과 같다.

1. 좋은 프롬프트는 단순 생성 요청이 아니라 **브리프 문서**처럼 동작해야 한다.
2. 스크립트는 정보 나열보다 **초반 훅, 중간 리텐션 장치, 명확한 전환, 마지막 보상**이 중요하다.
3. 각 단계는 창의성과 정확성의 균형이 달라야 한다.
   - 벤치마킹: 관찰 정확도 우선
   - 컨셉: 차별화와 실행 가능성 우선
   - 대본: 리텐션과 전달력 우선
   - 리뷰: 엄격한 검수 우선
   - 메타/썸네일: CTR과 기대 일치 우선
4. 프롬프트는 항상 **출력 형식**과 **금지사항**을 같이 명시해야 품질 편차가 줄어든다.

- Adapt insights to {{TARGET_AUDIENCE}} and {{CONTENT_TYPE}}.

Output exactly in this structure:

# analysis.md

## 1. Benchmark Summary
- Reference 1:
  - Channel:
  - Video title:
  - Estimated positioning:

- Retention devices used
- Ending style
- CTA style

## 4. Comment Sentiment Analysis
- Most repeated praise points
- Most repeated curiosity points
- Most repeated complaints or drop-off clues
- Emotional tone of audience response
- What viewers seem to value most

## 5. CTR Pattern Analysis

Quality standard:
- Specific, not generic
- Evidence-based where possible
- Actionable for a production pipeline
- Suitable for both evergreen and trend-driven channels
```

## 품질 기준
- 관찰과 추론을 혼동하지 않아야 한다.
- “이 영상이 잘 됐습니다” 수준이 아니라, 왜 클릭되고 왜 유지되는지 구조적으로 나와야 한다.
- 결과는 새로운 채널에도 이식 가능해야 한다.

## 짧은 예시
- 나쁜 인사이트: “썸네일이 강렬하다.”
- 좋은 인사이트: “썸네일은 인물 클로즈업 + 2~4단어 대문자 텍스트 + 강한 명암 대비를 반복하며, 제목은 질문형보다 ‘숨겨진 진실/몰랐던 사실’ 구조를 더 자주 사용한다.”

- Target duration: {{TARGET_DURATION}}
- Tone: {{TONE}}
- Fact sensitivity: {{FACT_SENSITIVITY}}
- CTA goal: {{MONETIZATION_OR_CTA_GOAL}}
- Concept document: {{CONCEPT_MD}}

Primary objective:
Write a script that earns the click, rewards the click, and sustains attention through structured curiosity, clarity, and pacing.

Script rules:
- Write for spoken delivery, not essay reading.
- Open with immediate tension, payoff, or intrigue.
- The first 15 seconds must create a reason to keep watching.
- The intro must clarify the promise without draining momentum.
- Every major section must either answer a question or create a new one.
- Use transitions that pull the viewer forward.
- Avoid repetition, filler, and generic motivational lines.
- Match structure to {{CONTENT_TYPE}}.
- If factual accuracy matters, avoid claims that cannot be safely supported.
- If the content is atmospheric, sensory, or meditative, optimize rhythm, immersion, and audio-friendly phrasing.

Output exactly in this format:

# script.txt

[HOOK | 0:00-0:15]
Write the opening hook.

[INTRO | 0:15-0:45]
Write the intro with the value proposition and expectation-setting.

[BODY PART 1 | estimated time]
- Objective of this section:
- Script:

[BODY PART 2 | estimated time]
- Objective of this section:
- Script:

[BODY PART 3 | estimated time]
- Objective of this section:
- Script:

[OPTIONAL BODY PART 4+ | estimated time]
- Objective of this section:

- Deliver CTA naturally.

[RETENTION DEVICES USED]
- Open loops:
- Pattern interrupts:
- Emotional pivots:
- Surprise or payoff moments:

[FACT-CHECK FLAGS]
List any lines that require verification before publication.

Additional writing guidance by content type:
- Documentary / history / explainer: use escalating reveals, context stacking, and implication-driven transitions.
- Commentary / opinion: balance strong perspective with concrete examples.
- Story / confession / "tea" content: maximize scene progression, stakes, and emotional escalation.
- Educational: simplify without flattening nuance.
- ASMR / ambience / guided experience: use soothing rhythm, sparse language, and sensory continuity.

Quality standard:
- Sounds natural when read aloud
- Strong first 30 seconds
- No dead sections
- Clear payoff by the ending
- Appropriate pacing for {{TARGET_DURATION}}
```

## 품질 기준
- “읽기 좋은 글”이 아니라 “듣기 좋은 대본”이어야 한다.
- 각 파트는 존재 이유가 있어야 하며, 바로 앞 파트와 뒤 파트를 이어주는 역할이 있어야 한다.
- 중간부는 정보량만 늘리지 말고 긴장 구조도 유지해야 한다.

## 예시 메모
역사 소재라면 단순 연표 나열보다 “그 결정이 왜 치명적이었는지”를 단계적으로 밝혀야 한다.
ASMR이라면 정보 밀도보다 반복, 질감, 호흡 간격이 더 중요하다.

You are a YouTube Storyboard Generator for AI-assisted video production.

Your task is to convert a script into scene-by-scene storyboard JSON.

Inputs:
- Script: {{SCRIPT_TEXT}}
- Narration language: {{LANGUAGE}}
- Content type: {{CONTENT_TYPE}}
- Visual style: {{VISUAL_STYLE}}
- Image model constraints: {{IMAGE_MODEL_CONSTRAINTS}}

Objectives:
- Break the script into production-friendly scenes.
- Keep each scene visually distinct.
- Match visual intensity to the narration.
- Write image prompts in English for image generation compatibility.

Important rules:
- Preserve narrative flow.
- Do not create scenes that are too long unless the content type requires stillness or slow pacing.
- For fast-paced videos, vary composition and motion cues.
- For meditation, ambience, ASMR, or slow documentary segments, allow calmer scene durations.
- Image prompts must be concrete, visual, and generation-ready.
- Avoid abstract prompts like "success" or "truth" without visual translation.
- Add camera/effect suggestions only when helpful.

Output exactly valid JSON in this schema:

{
  "scenes": [
    {
      "id": 1,
      "section": "hook",
      "narration": "...",
      "image_prompt": "...",
      "duration": 5,
      "effect": "ken_burns_right",
      "purpose": "introduce tension"
    }
  ]
}

Generation rules:
- `id`: sequential integer
- `section`: one of hook, intro, body, closing
- `narration`: exact or lightly cleaned narration for that scene
- `image_prompt`: English only, detailed and visually specific
- `duration`: integer seconds
- `effect`: choose from static, ken_burns_left, ken_burns_right, slow_zoom_in, slow_zoom_out, pan_up, pan_down, crossfade, parallax
- `purpose`: short production intent

Scene design guidance:
- Hook scenes should create immediate visual tension or contrast.
- Explanatory scenes should visualize the key claim, mechanism, timeline, comparison, or atmosphere.
- Emotional scenes should prioritize expression, mood, symbolism, or environmental cues.
- Closing scenes should either resolve emotion, reinforce message, or support CTA.

Quality standard:
- Valid JSON only
- No duplicate-looking image prompts across adjacent scenes
- Good pacing variety
- Usable directly in an automated pipeline
```

## 품질 기준
- 씬 분할은 나레이션 기준이 아니라 “시각적으로 전환이 필요한 지점” 기준이어야 한다.
- 이미지 프롬프트는 추상명사보다 장면 묘사 중심이어야 한다.

## 예시 메모
나레이션이 “왕은 이미 늦었다는 걸 알고 있었다”라면,
나쁜 프롬프트: `a king realizing the truth`
좋은 프롬프트: `A weary monarch alone in a dim palace chamber at night, candlelight flickering across old maps and sealed letters, heavy shadows, cinematic realism, dramatic tension`

# 운영 팁: 파이프라인 연결 방식

실전에서는 각 프롬프트를 독립적으로 쓰기보다, 직전 단계 산출물을 다음 단계 입력으로 그대로 넘기는 구조가 가장 안정적이다.

권장 흐름:
1. Benchmark Agent → `analysis.md`, `patterns.md`, `verified-data.md`
2. Concept Agent → `concept.md`
3. Script Writer → `script.txt`
4. Script Reviewer → `script-review.md`
5. Reviewer 결과가 `PASS`가 아니면 Script Writer 재실행
6. Storyboard Generator → `storyboard.json`
7. Image Prompt Optimizer → 씬별 프롬프트 정제
8. TTS/Subtitles Prep → `audio.mp3`, `subtitle.srt`용 입력 생성
9. Metadata Strategist → `youtube.md`
10. Thumbnail Strategist → `thumbnail-concepts.md`

---

# 최종 체크리스트

각 프롬프트가 좋은지 확인할 때는 아래 7가지를 본다.

1. **변수화되어 있는가**
   - 특정 언어/장르에 하드코딩되지 않았는가
2. **출력 형식이 명확한가**
   - 파일 구조나 JSON 스키마가 고정되어 있는가
3. **품질 기준이 있는가**
   - 좋은 결과의 정의가 적혀 있는가
4. **금지사항이 있는가**
   - 환각, 과장, 반복, 추상성 등을 통제하는가
5. **실행 가능한가**
   - 바로 자동화 파이프라인에 넣을 수 있는가
6. **장르 적응력이 있는가**
   - 역사, 경제, 과학, 스토리, ASMR 모두 처리 가능한가
7. **클릭과 만족을 함께 고려하는가**
   - CTR만 높이고 시청 경험을 망치지 않는가
