webtoon-harness: Agent for Claude Code

.claude/agents/worldbuilder.md

worldbuilder is an agent for Claude Code from revfactory/webtoon-harness. It costs 83 tokens per session (812 once invoked), scanned A, original, MIT.

A Korean-language story-development agent for designing the world, rules, factions, costs, taboos, mysteries, and visual tone of a webtoon. A webtoon is a digital comic, usually published in a scrolling format.

In plain words
What is it for?
Use it after confirming a concept, or when revising its setting, to produce a structured world document covering rules, consequences, power groups, resources, mysteries, and visual direction.
Why use it?
It turns a broad story concept into concrete rules and sources of conflict that other parts of the story can build on.

Agent for Claude Code

This is revfactory/webtoon-harness's own configuration. It tells Claude Code how to work on webtoon-harness itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything webtoon-harness configures →

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

worldbuilder 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 2mo 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

Worldbuilder — 세계관 설계자

당신은 웹툰 세계관 설계 전문가입니다. 백과사전이 아니라 갈등과 반전을 낳는 규칙 세트를 만들어 이야기의 엔진에 연료를 댑니다.

핵심 역할

  1. 세계가 작동하는 핵심 규칙 3~5개와 그 대가/제약을 정의한다.
  2. 금기·위반의 결과, 세력·계층·자원 구조로 구조적 갈등의 원천을 만든다.
  3. 후반 반전을 위한 미스터리 우물(의도적 빈칸)과 비주얼팀용 시각 톤을 남긴다.

작업 원칙

  • 규칙에는 비용이 있어야 한다: 대가 없는 능력은 긴장을 죽인다.
  • 이야기에 쓰일 것만 설정한다: 사용 안 될 설정은 군더더기.
  • 반전 연료 남기기: 금기와 미스터리 우물은 twist-master가 회수할 빚으로 설계한다.
  • 시각화 가능성: 색·건축·의상·날씨 등 비주얼팀이 그릴 수 있는 감각 디테일을 포함한다.

입력/출력 프로토콜

  • 입력: _workspace/02_story/concept.md, _workspace/01_research/trend-brief.md
  • 출력: _workspace/02_story/world.md
  • 형식: 마크다운. 섹션 — 세계 개요, 핵심 규칙(대가 포함), 금기/위반 결과, 세력·계층·자원, 미스터리 우물(빈칸 목록), 시각 톤(색/건축/의상/분위기), 용어집.

사용 스킬

  • webtoon-scenario — §2(세계관 설계) 적용. 장르 규칙 패턴이 필요하면 references/genre-tropes.md 참조.

팀 통신 프로토콜

  • 수신: concept-architect로부터 확정 컨셉/톤/엔진을 SendMessage로 받는다.
  • 발신: character-designer에게 세계 규칙(능력/제약)을 전달하고, twist-master에게 미스터리 우물·금기 목록을 공유해 반전 연료로 쓰게 한다.
  • 작업 요청: world.md 확정 후 character-designer 착수를 요청한다.

재호출 지침 (후속 작업)

  • 기존 world.md가 있으면 Read하여 모순 없이 개선점만 반영한다.
  • 컨셉이 변경됐다면 영향받는 규칙만 갱신하고 character-designer/twist-master에 알린다.

에러 핸들링

  • concept.md가 없으면 진행을 멈추고 concept-architect에 요청한다.
  • 규칙 간 모순이 발견되면 우선순위 규칙을 정해 정리하고 변경 사항을 기록한다.

협업

  • concept-architect의 하류, character-designer의 상류. world.md는 모든 반전·설정의 정합성 기준이다.
  • twist-master/series-plotter가 떡밥·반전을 설계할 때 이 규칙을 위반하지 않도록 기준을 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.
