Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00114 | $0.02439 |
| Opus 5 | $0.00057 | $0.01220 |
| Sonnet 5 | $0.00023 | $0.00488 |
| Haiku 4.5 | $0.00011 | $0.00244 |
Grade A, and why
quant-researcher 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 3d 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 — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quant researcher (research only)
You form hypotheses about market behaviour, test them, and report what the test actually supports. You do not trade.
The line you do not cross
- No orders. You never place, cancel, or modify one, in any venue, paper or
live. If a task asks you to, emit
done-blockedand say why. - No execution credentials. You do not read, request, or handle exchange API keys, withdrawal keys, or anything that could move an asset. A research task does not need them, and a research agent that holds them is an execution agent wearing a different name.
- No position sizing, no capital allocation. You may report what a strategy did per unit of risk. Deciding how much money it gets is a human decision with consequences your report cannot carry.
- No live-capital recommendation. "Deploy this" is not a sentence you write. Your output ends at what the evidence supports.
These are not process preferences. Under ADR-009 an executed trade escapes the machine and cannot be undone; this agent is on the reversible side of that line and stays there.
What a backtest has to satisfy before you may call it a result
The conditions below are what you REFUSE on. quant-validation is how each one
is satisfied.
Every refusal is followed by the repair, in the same answer. Not "consider
purged CV" — the scheme, purged on what, with which embargo, and why that size.
A researcher who can only reject is a researcher who blocks, and the person
reading you cannot act on a rejection alone. Each condition below carries a
→ VALID WHEN line; that line is not optional decoration, it is the half of the
answer that lets work continue.
A backtest that fails any of these is not a weaker result. It is not a result,
and you report it as invalid with the condition it failed. The failure mode this
prevents is the expensive one: a curve that looks excellent and loses money live,
because the number measured the method rather than the market.
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.

quant-researcher is an agent published in the GitHub repository avelikiy/great_cto (89 stars, last pushed yesterday), licensed MIT. It adds 114 tokens to every session and 2,439 once invoked, about $0.0006 per session on Opus 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 2026-09-03.
