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.

Fable 5.1 $0.01715 $0.01715
Opus 5.5 $0.00686 $0.00686

Security

Grade A, and why

ko-design-md 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 10d 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.

ko-design-md

한국 브랜드의 디자인 언어를 DESIGN.md 문서(services/{slug}.md)로 정리한 오픈 카탈로그. TanStack Start 사이트(getdesign.kr)가 이를 서빙하고, /design-md 스킬(.claude/skills/design-md)이 새 항목 온보딩 파이프라인을 자동화한다. 패키지 매니저는 pnpm (npm 금지).

검증 커맨드 (CI 게이트와 동일)

pnpm typecheck && pnpm lint && pnpm format:check
pnpm test               # vitest — .claude/{worktrees,cache}/ 와 e2e/ 는 제외됨

단일 파일 검사: pnpm validate:draft <file.md> [--slug X --expected-logo <url> --lang ko], pnpm validate:previews --slug <slug> --verbose. 검증기 메시지가 막는 이유와 고치는 법을 말한다 — 막히면 메시지를 따르고, 통과하려고 값을 지어내지 말 것. 프리뷰 대비 기준선 게이트 pnpm gate:contrast 는 위 묶음에 없다(.claude/rules/preview.md).

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.
