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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00078 | $0.01229 |
| Opus 5 | $0.00039 | $0.00615 |
| Sonnet 5 | $0.00016 | $0.00246 |
| Haiku 4.5 | $0.00008 | $0.00123 |
Grade A, and why
cover-design 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cover Design
책의 표지 이미지를 설계·생성한다. 결과는 {slug}/cover.png (1600×2560 권장) + 재생성용 프롬프트 기록.
절차
- 입력 확인 — 책 제목, 부제(있으면), 주제 분위기, 대상 독자
- 콘셉트 3안 구상
- A: 미니멀리즘 — 심볼 하나 + 큰 타이포
- B: 일러스트형 — 주제 메타포 이미지
- C: 타이포그래피 중심 — 제목 자체가 그래픽
- 추천안 선택 — 주제 톤·대상 독자에 가장 맞는 1안
- 프롬프트 작성 — 영어 프롬프트 권장 (이미지 모델 대부분 영어 최적화)
- 이미지 생성 — 사용 가능한 도구 순서로 시도
- 결과 검증 — 해상도, 구도, 제목 가독성 확인
- 저장 —
cover.png+cover_prompt.md
콘셉트 선택 가이드
| 주제 톤 | 추천 콘셉트 |
|---|---|
| 차분한 기술서 | A (미니멀리즘, 차분한 색조) |
| 철학·에세이형 | C (타이포그래피, 따뜻한 색) |
| 실전 튜토리얼 | B (일러스트, 선명한 색) |
| 심화·이론서 | A (미니멀, 깊이 있는 색) |
프롬프트 작성 원칙
- 스타일 지정: "minimalist book cover", "editorial illustration", "modernist typography"
- 색상 톤: "warm muted palette", "deep blue and gold"
- 분위기: "contemplative", "bold", "serene"
- 구도: "title prominent in upper third, small author attribution at bottom"
- 제외: "no cheesy stock photo aesthetic", "no generic tech gradient"
- 해상도·비율: "portrait orientation, 1.6:1 aspect ratio"
예시 프롬프트:
A minimalist book cover in portrait format (1600x2560).
Title "효과적인 SQL 쿼리 튜닝" in bold modern sans-serif
occupying the top third. Center: a single abstract symbol
resembling an interconnected graph in deep indigo.
Background: warm off-white. Bottom-right: "Toby-AI"
in small elegant serif. Editorial, calm, confident.
No stock photography. No generic tech gradient.
이미지 생성 도구 우선순위
- 이미지 생성 MCP (설치되어 있으면) — 가장 선호
- 외부 API — OpenAI
gpt-image-1, Stability SDXL 등 (사용자 API 키 필요) - ImageMagick 폴백 — 단순 타이포그래피 플레이스홀더
ImageMagick 폴백 명령

검증 체크
- 해상도 ≥ 1600×2560
- 썸네일(200×320)로 축소해도 제목 읽힘
- 저자 표기 존재 (기본값
Toby-AI, 사용자 지정 시 그 값 — 이미지 안 또는 메타데이터 예정) - 클리셰 회피 (기본 그라데이션, 스톡사진 느낌 없음)
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.
- 9d ago First seen · 110 lines · 78 tokens per session scan A 71d56cc7123a
cover-design is a skill published in the GitHub repository tobyilee/book-writer (81 stars, last pushed 23d ago), licensed MIT. It adds 78 tokens to every session and 1,229 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
