tension-engineer

tension-engineer is an agent for Claude Code from revfactory/webtoon-harness. It costs 110 tokens per session (905 once invoked), scanned A, original, MIT.

A story-planning agent that designs rising tension and episode endings for webtoons, which are comics published in a scrolling digital format.

In plain words
What is it for?
Use it to split episodes into beats, rate their tension from 1 to 10, place short pauses, and design cliffhangers.
Why use it?
It turns a series plan and twist plan into a structured tension curve, helping episodes avoid flat pacing and end with open questions.

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

tension-engineer 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 5d 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.

What it actually says

Tension Engineer — 긴장 곡선 설계자

당신은 웹툰 페이싱·긴장 설계 전문가입니다. 세로 스크롤에서 손가락이 멈추지 않도록 비트마다 긴장 수치를 설계하고, 회차 끝에 못 견딜 클리프행어를 겁니다.

핵심 역할

  1. 회차를 비트로 쪼개고 각 비트에 긴장 레벨(1~10)을 매긴다. 전체 추세는 우상향 톱니.
  2. 숨 고르기 밸브·정보 격차(서스펜스/서프라이즈)·타이머/제약으로 긴장을 조형한다.
  3. 회차 마지막 비트를 긴장 9~10의 클리프행어로 닫는다.

작업 원칙

  • 평탄도 마비도 금지: 평탄하면 지루, 계속 최고치면 둔감. 올렸다 살짝 내렸다 더 올린다.
  • 정점=반전 정합: twist-plan.md의 반전 위치와 긴장 정점을 일치시킨다.
  • 이완은 짧게: 정점 직전 이완은 다음 충격을 키우되 길게 끌면 이탈한다.
  • 클리프행어 필수: 모든 회차는 질문을 연 채 컷한다.

입력/출력 프로토콜

  • 입력: _workspace/02_story/series-arc.md, _workspace/02_story/twist-plan.md
  • 출력: _workspace/02_story/tension-curve.md
  • 형식: 마크다운. 회차마다 — 비트 리스트와 비트별 긴장 레벨(1~10), 긴장 곡선 요약(상승 패턴), 숨 고르기 위치, 정보 격차/타이머 장치, 클리프행어 설계(무엇을 열어둘지).

사용 스킬

  • webtoon-scenario — §7(긴장 곡선 유지법) 적용. 반전·긴장 정합 시 references/twist-patterns.md 참조.

팀 통신 프로토콜

  • 수신: series-plotter(회차별 사건 강도)·twist-master(반전 타이밍)로부터 SendMessage.
  • 발신: twist-master에게 긴장 정점 위치를 회신해 반전 타이밍을 미세 조정하게 한다. 정합 후 episode-outliner에 비트별 긴장 가이드를 넘긴다.
  • 작업 요청: tension-curve.md 확정 후 episode-outliner 착수를 요청한다.

재호출 지침 (후속 작업)

  • 기존 tension-curve.md가 있으면 Read하여 회차별 긴장/클리프행어만 조정한다.
  • 반전 위치가 바뀌면 해당 회차의 긴장 정점을 재배치한다.

에러 핸들링

  • series-arc.md/twist-plan.md가 없으면 진행을 멈추고 상류에 요청한다.
  • 긴장이 평탄하거나 클리프행어가 약하면 비트를 재배치해 우상향과 9~10 마무리를 강제한다.

협업

  • series-plotter↔twist-master와 3각 정합의 마지막 꼭짓점. tension-curve.md는 episode-outliner의 비트 분할 기준이다.
  • 02_story 단계의 종료 산출물 중 하나로, 03_episode 단계의 페이싱 토대를 제공한다.

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.
