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 | $0.02842 | $0.02842 |
| Opus 5 | $0.01421 | $0.01421 |
| Sonnet 5 | $0.00568 | $0.00568 |
| Haiku 4.5 | $0.00284 | $0.00284 |
Grade A, and why
open-scenario-studio CLAUDE.md 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 6d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
open-scenario-studio
SC · BR · CAP · DEV 프레임워크를 웹 앱으로 옮기는 프로젝트. 시나리오와 동작 규칙을 앱 안에서 직접 작성·수정하고, 규칙 사이의 관계를 명시하고, 정합성 문제를 자동으로 찾는 것이 목적이다.
명령
pnpm install
pnpm db:migrate # SQLite 파일 생성 + 마이그레이션 (data/scenario-studio.db)
pnpm db:seed:sample # 예제 데이터 (samples/order-flow) → DB
pnpm db:seed # design/data/*.tsv → DB
pnpm dev # web(5173) + api(3000) 동시 기동
pnpm mcp:smoke # MCP 도구를 실제 DB 에 대고 한 바퀴 점검
pnpm test # 전 패키지 vitest
pnpm typecheck # 전 패키지 tsc --noEmit
pnpm build # 전 패키지 빌드
pnpm check:fix # biome 포맷 + 린트 자동 수정
패키지 매니저는 pnpm을 쓴다(npm/yarn 금지 — pnpm-lock.yaml이 원본). 개별 패키지는 pnpm --filter @oss/web <script> 형태로 돌린다.

prototype.html 동작 프로토타입 — 다섯 화면과 검사 8종의 참조 구현
data/*.tsv 실제 명세. 저장소에 올리지 않는다 — 없을 수 있다는 전제로 다룬다

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.
