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

data-provenance-audit 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 17d 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

데이터 출처와 계산 검수

원본 파일과 외부 데이터 서비스를 변경하지 않고 산출물의 근거를 대조한다.

  • 인용된 KOSIS 통계표 ID, DART 접수번호, data.go.kr 데이터셋 또는 건축물 질의 조건을 찾고 지역·기간·단위가 주장한 수치와 맞는지 확인한다. 원문을 볼 수 없으면 출처 확인은 미검증으로 남긴다.
  • 표·차트·본문·요약의 수치와 축 단위, 날짜가 원자료와 같은지 확인한다. 합계·증감률·평균·면적당 가격 등 계산은 입력값으로 다시 산출한다.
  • 주민등록번호, 전화번호, 개인 주소, 계좌번호 등 불필요한 개인 식별 정보가 산출물에 드러나는지 확인한다.
  • 조회 실패를 추정값으로 바꿔 적었는지, 실측·추정·예측을 구분했는지 확인한다.

보고서는 판정(PASS/FAIL/미확인), 확인 자료, 위치·근거가 있는 발견, 재계산 표, 출처 범위 대조, 미검증 항목으로 쓴다. 확인하지 못한 수치를 PASS로 채우지 않는다. 독립된 검수자를 실행하지 않았다면 독립 감사라고 부르지 않는다.

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.
