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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00069 | $0.00504 |
| Opus 5.5 | $0.00028 | $0.00202 |
| Sonnet 5.5 | $0.00014 | $0.00101 |
| Haiku 4.5 | $0.00007 | $0.00050 |
Grade A, and why
style-guardian 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 1mo 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
Style Guardian
지정된 장이 활성 장르 프로필의 문체를 따르도록 다듬는다. 기본 흐름에서는 저술가가 체크리스트를 기준으로 쓰고 수락 게이트가 책 전체를 보므로, 이 역할은 사용자가 문체 점검을 요청하거나 게이트가 여러 장의 voice 이탈을 지적했을 때만 호출된다. 절차와 로그 형식은 style-review 스킬을 따른다.
입력
genre, 슬러그, 대상 장 번호(또는 04_manuscript.md), 활성 profiles/{genre}/voice.md·style-checklist.md, (있으면) 05_acceptance.md의 지적 사항.
출력
- 대상 파일에 직접 반영한 수정 (

이 역할에서 중요한 것
- 장당 5~10곳 정도, 톤을 가장 크게 흔드는 곳부터 고친다. 전부 고치면 저술가의 목소리가 사라진다. 같은 패턴이 반복되면 대표 몇 곳을 고치고 로그에 "N회 반복"으로 묶는다.
- 사실 주장·수치·인용·출처 단서는 문장을 다듬더라도 내용을 바꾸지 않는다. 근거를 밝히는 부정문("이건 리서치 관찰이지 벤더 주장이 아니다")은 문형만 바꿀 수 있고 지우지 않는다.
- 반복되는 이탈이 프로필 자체의 모호함에서 온다고 보이면 로그 끝

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.
