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 | $0.00283 | $0.00283 |
| Opus 5.5 | $0.00113 | $0.00113 |
| Sonnet 5.5 | $0.00057 | $0.00057 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
medsci-skills 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 24d 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
Working in this repository (Codex and other agents)
CLAUDE.md carries the same instruction for Claude Code, with its history. Codex reads this file,
not that one, so the fence is repeated here.
_corpus/ — do not read it, do not run anything against it
_corpus/ is gitignored and may exist in a maintainer's working tree. Its heldout/ papers are a
frozen test set: a number measured on them means no detector was written knowing these papers, and
reading one in order to write or justify a change is how a detector comes to know it.
- Do not open files under
_corpus/. - Do not run a detector,
grep,find, or any scan across it. Name directories (skills/,scripts/,tests/) instead of scanning the repository root, or exclude it explicitly (--exclude-dir=_corpus). - Do not cite a number derived from it as evidence for changing a detector.
- If a task seems to require it, stop and ask. It almost certainly does not.
Everything else
CONTRIBUTING.md is the entry point: what to run before pushing (CI is the merge gate), the
worktree discipline, and what a change is expected to ship with.
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.

medsci-skills AGENTS.md is an instructions file published in the GitHub repository Aperivue/medsci-skills (349 stars, last pushed 2d ago), licensed MIT. It adds 283 tokens to every session, about $0.0011 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-30.
