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 | $0.00113 | $0.00113 |
| Opus 5.5 | $0.00045 | $0.00045 |
| Sonnet 5.5 | $0.00023 | $0.00023 |
| Haiku 4.5 | $0.00011 | $0.00011 |
Grade A, and why
dartlab 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
DartLab Agent Bootstrap
작업 시작 전에 CLAUDE.md를 끝까지 읽는다.
CLAUDE.md는 공통 안전 경계와 문서 지도만 소유한다. 설계와 운영 계약은
src/dartlab/skills/specs/**가 정본이며, 변경 범위에 맞는 Skill OS 문서를 따라간다.
이 파일에는 규칙을 복제하지 않는다. 충돌하면 CLAUDE.md가 안내한 정보 소유권을 기준으로 판단한다.
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.
