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 | $0.00449 | $0.00449 |
| Opus 5.5 | $0.00180 | $0.00180 |
| Sonnet 5.5 | $0.00090 | $0.00090 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
project-legibility AGENTS.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 2mo 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
AGENTS.md
- 일반 문서와 작업 기록은 한국어를 기본으로 쓰고, 공개 진입 문서는
*.en.md영어 pair를 함께 유지한다. - 요청 범위 안의 구현과 검증은 직접 완료한다. 새 제품 정책, 영구 검증이나 release 전환처럼 별도 수명주기를 만드는 변경은 사용자 요청 또는 현재 정본의 승인된 결정에 연결한다.
- 개별 스킬 저장소가 정본이다. 제품 약속이나 bundle 구성을 바꿀 때는
docs/PRODUCT.md를 먼저 갱신한다. 정본 스킬 내용을 바꿨다면 해당 저장소에서 검증·push하고, 이후scripts/sync_skills.py로 생성 bundle과 lock을 맞춘다.plugins/project-legibility/skills/는 직접 수정하지 않는다. - 폐기할 실험·브라우저 검증 코드, 실행 상태와 원시 출력은 사용자 환경과 분리한 저장소 밖 임시 위치에 두고 확인 뒤 정리한다. 보존할 코드와 증거는 정식 소스, 테스트, 런북 또는 산출물 owner에 둔다.
docs/tasks/에는 사람이 읽는 현재 상태, 목적, 방법, 결과, 결정과 간결한 근거 요약만 둔다.- 삭제·교체는 현재 정본과 구성에서 대상을 제거해 표현한다. denylist나 tombstone은 현재 외부 안전·호환성 계약이 요구하고 범위와 해제 조건이 정해진 경우에만 둔다.
- plugin version, 한영
CHANGELOG, tag와 publisher pin은 실제 게시를 수행하는 별도 release 작업에서 릴리스 런북에 따라 함께 갱신한다. publisher marketplace는perhapsspy/codex-plugins에서 push된 Project Legibility release commit만 고정한다.

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.
