quant

A quantitative analysis tool for prices, trading volume, market factors, risk, public filings, rankings, portfolios, and strategy tests. A backtest checks how a trading strategy would have performed on past data.

In plain words
What is it for?
Use it to calculate indicators, momentum, beta, volatility, factor signals, rankings, portfolio risk, price-versus-earnings gaps, and backtests.
Why use it?
It brings market signals and strategy checks into one analysis tool, while distinguishing measured market expectations from real analyst forecasts.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

quant 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 yesterday.

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.

엔진 역할

quant는 가격/거래량/수급/팩터/공시 텍스트/포트폴리오/전략을 정량적으로 계산하는 L2 엔진이다. 재무제표의 회계적 인과 해석은 analysis, 시장 레벨 매크로 해석은 macro, 후보 유니버스 발굴은 scan이 담당한다.

공개 호출 방식

import dartlab

guide = dartlab.quant()

tech = dartlab.quant("지표", "005930")
verdict = dartlab.quant("판단", "005930")
beta = dartlab.quant("베타", "005930", benchmarkMode="sector")
ranking = dartlab.quant("순위")
portfolio = dartlab.quant("리스크패리티", ["005930", "000660"])

c = dartlab.Company("005930")
company_quant = c.quant("모멘텀")
divergence = c.quant("괴리")

괴리는 Quant 대표 제품이다. 공시 이익 변화, 시장 횡단면 이익 서프라이즈 프록시, 가격 반응을 비교한다. 실제 애널리스트 컨센서스가 없으면 이를 기대치로 가장하지 않고 product.gapsquant.analystConsensus로 남긴다.

강행 호출 룰 (agent 답변 품질 회귀 차단)

46 axis 질문 (베타·모멘텀·변동성·factor·forecast·backtest 등) 에서 다음 4 룰 강행 - 위반 시 refs=0 회귀.

  1. 1 차 도구는 EngineCall 강제. EngineCall(apiRef="quant", args={"axis": "베타", "stockCode": "005930"}) 양식. RunPython 직접 numpy/polars 계산은 engine 결과 부재 시에만 fallback - 처음부터 raw 계산 금지.
  2. 본문 안 숫자에 inline ref 표기 필수 - [tableRef:...] 또는 [valueRef:...] 형식. ref 없는 quant 결과는 답변 보류.
  3. backtest 결과는 executionRef 명시 - 백테스트 일자 / 룰 / 파라미터 ref 박지 않으면 hindsight 환각.
  4. forecast/walkforward 같은 가정 강한 축은 [conf:30] 기본 - 가정 (lookahead window · trend assumption) 본문에 명시.

호출 동작

무인자 dartlab.quant()는 46개 축 가이드 DataFrame을 반환한다. axis와 종목을 주면 가격/거래량/재무/공시 snapshot을 읽어 축별 결과를 계산한다.

축은 단일 종목 축, 종목 불필요 횡단면 축, 종목 리스트 포트폴리오 축, rule/style 기반 전략 축으로 나뉜다. 필요한 입력이 없으면 가이드 또는 오류/제한을 반환하고 값을 만들지 않는다.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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 is a skill published in the GitHub repository eddmpython/dartlab (209 stars, last pushed 10d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 11,704 tokens. 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.
