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 | $0.03558 | $0.03558 |
| Opus 5.5 | $0.01423 | $0.01423 |
| Sonnet 5.5 | $0.00712 | $0.00712 |
| Haiku 4.5 | $0.00356 | $0.00356 |
Grade A, and why
OpenOnco 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 19d 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.
How it starts
The opening of the file, as written. The whole thing — 295 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project: OpenOnco
Free public resource for oncology clinical decision support. User uploads a patient profile → receives two alternative treatment plans (standard + aggressive) with full source citations. Plans refresh as new data arrives (new labs, doctor decisions, updated guidelines).
Documentation snapshot: 2026-10-10. Latest tagged software release: v0.1.3;
the deployed website also includes later master changes. Browser engine,
Onco Wiki, Handbook (English MVP), bilingual site navigation and a synthetic
DLBCL review packet are available. Clinical content remains provisional according
to entity review status. See README.md, docs/DEVELOPMENT.md and
docs/SEARCH_INDEXING.md for current usage and delivery details.
Source of truth hierarchy
When instructions conflict, obey this order:
specs/CHARTER.md— project governance + scope- Other
specs/*.md— clinical, data, schema, source, reference case - This
CLAUDE.md README.md- Anything under
legacy/— not authoritative; historical reference only
legacy/ contains the pre-OpenOnco autoresearch pipeline. Retired (not
deleted) because the LLM-ranks-treatments pattern conflicts with CHARTER
§8.3. Don't use it as a pattern for new work.

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.

OpenOnco CLAUDE.md is an instructions file published in the GitHub repository romeo111/OpenOnco (2 stars, last pushed today), licensed MIT. It adds 3,558 tokens to every session, about $0.0142 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 2026-08-31.
