market-scan is a skill for Claude Code from gejyn14/kiwoom-plugin. It costs 84 tokens per session (821 once invoked), scanned A, original, Apache-2.0.

A Korean-language guide for scanning the South Korean stock market. It covers rankings, sectors, themes, exchange-traded funds (ETFs), program trading, and live quotes for KOSPI and KOSDAQ.

In plain words
What is it for?
Use it to find stocks with high volume, large price moves, trading-value rankings, strong themes, ETF information, sector performance, or current quotes.
Why use it?
It helps choose the correct market query and required subcommand instead of guessing unsupported options. It also explains which requests need a date or a finite live-stream duration.

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

market-scan 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 8d 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

시장 훑기

순위 (28종)

종류는 하위 명령이다 (--marketall/kospi/kosdaq):

kiwoom_run(["market","rank","volume","--market","kospi"])

자주 쓰는 것: volume(당일 거래량), change(전일대비 등락률), amount(거래대금), volume-surge(거래량 급증), foreign-inst(외국인/기관 매매 상위), new-highlow(신고저가), limit(상하한가).

전체 목록은 kiwoom_describe(["market","rank"])로 확인한다 — 28종이라 외우지 말고 필요할 때 조회한다. 시가총액 순위는 없다 — 없는 종류를 지어내지 말고 목록에서 고른다.

그 밖

market sector·theme·etf·program은 전부 그룹이다. 그대로 호출하면 INVALID_INPUT이 나므로 하위 명령까지 내려간다.

  • 업종 지수: kiwoom_run(["market","sector","index"]) — 기본 --sector-code 001(KOSPI종합), KOSDAQ종합은 101. 업종별 등락은 market sector investor, 개별 업종은 market sector current <업종코드>.
  • 테마: kiwoom_run(["market","theme","groups"]) — "무슨 테마가 강한지" 물을 때. 구성종목은 market theme stocks <테마코드>.
  • ETF: kiwoom_run(["market","etf","all"]) — 개별 ETF는 market etf info <코드>.
  • 프로그램매매: kiwoom_run(["market","program","time-trend","--date","<YYYYMMDD>"])--date필수다. 일자별은 market program daily-trend.

실시간

지금 이 순간의 호가·체결을 보려면 kiwoom_stream_snapshot을 쓴다:

kiwoom_stream_snapshot(stream_type="quote", symbols=["005930"], max_events=10, duration="15s")

반드시 유한하게 끝난다 — max_eventsduration 중 먼저 닿는 쪽에서 종료한다. 장 시간이 아니면 이벤트가 오지 않고 시간만 흐르므로, 장외 시간에는 stock info로 종가를 보는 편이 낫다.

답할 때

  • 순위표를 통째로 붙이지 않는다. 상위 몇 개를 추리고 무엇이 눈에 띄는지 말한다 — 한 업종이 상위를 채우고 있다든가, 거래량이 평소와 다르다든가.
  • 상승 빨강 / 하락 파랑 (한국 관습).
  • 장 시간을 의식한다. 국내장은 09:00–15:30 (KST). 장 마감 후의 "오늘 시장"은 종가 기준이라는 점을 밝힌다.
  • meta.env"mock"이면 모의투자 서버 데이터이며 실제 시장과 다를 수 있다.
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.
