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 | $0.00050 | $0.00302 |
| Opus 5.5 | $0.00020 | $0.00121 |
| Sonnet 5.5 | $0.00010 | $0.00060 |
| Haiku 4.5 | $0.00005 | $0.00030 |
Grade A, and why
brain 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
Knowledge Brain Engine
Package brain_engine in knowledge-brain-engine/. Stdlib TF-IDF, no network. Exit codes: 0 sourced, 2 usage error, 3 refusal.
Commands (run from knowledge-brain-engine/)
python -m brain_engine ask "how do we handle FX on ACB?"
python -m brain_engine --cite "distributions draw exempt surplus first"
python -m brain_engine remediate "Surplus Review" # reviewer corrections -> apply-ready prompt
python -m brain_engine.loop --demo # INTEGRITY LOOP: re-derive tampered entries verbatim
python -m pytest -q # 7,011 tests
Loop verdicts (brain_engine/loop.py)
CLEAN (0) / REMEDIATED (0) / ESCALATED (3 — the engine's refusal code).
The signature rule: tampered text/speakers are re-derived BYTE-FOR-BYTE from Corpus.utterance_text; orphaned citations (no utterance behind them) are quarantined, never repaired — no source, no guess.
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.

brain is a skill published in the GitHub repository sophonfinance-wq/finance-automation-portfolio (16 stars, last pushed 27d ago), licensed MIT. It adds 50 tokens to every session and 302 once invoked, about $0.0002 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 2026-08-30.
