daangn-search

daangn-search is a skill for Claude Code from bam-bam-2/solo-skills. It costs 50 tokens per session (1,470 once invoked), scanned A, original, MIT.

A search method for 당근마켓, a Korean local marketplace for used goods, that searches many administrative areas by changing their numeric region codes.

In plain words
What is it for?
Use it to look for listings across Seoul and other Korean regions by keyword, including only items that are still for sale.
Why use it?
The website search covers only one neighborhood at a time, so a broad search requires visiting multiple region-specific searches and filtering out completed sales when needed.

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

daangn-search 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 13d 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.

당근마켓 광역 검색

당근 웹(www.daangn.com)의 중고거래 검색은 선택된 행정동 하나의 매물만 보여준다. "전국 검색" 기능이 없다. 넓게 찾으려면 지역코드를 바꿔가며 순회해야 한다.

URL 구조

https://www.daangn.com/kr/buy-sell/?in=x-<지역ID>&search=<검색어>&only_on_sale=true
  • in 파라미터의 이름 부분은 무시되고 숫자 ID만 유효하다. x-448처럼 아무 이름이나 써도 된다
  • only_on_sale=true 를 붙이면 거래완료 매물이 빠진다. 안 붙이면 결과 대부분이 이미 팔린 것
  • 응답은 서버사이드 렌더링이라 fetch만으로 매물이 다 들어온다 (브라우저 불필요)

지역 ID 지도 (2026-08 실측)

시도 순서로 연속 배치돼 있다. 서울은 구 단위로 아래와 같다.

용산 36~52 구로 281~296

경계는 정확하지 않다. 확인이 필요하면 아래로 지역명을 읽어 검증한다.

const m = html.match(/data-gtm="search_filter">([^<]+)</);  // "서울시 강동구 둔촌동"

매물 파싱

function parseL(html){
  const re=/<a data-gtm="search_article"[^>]*href="(\/kr\/buy-sell\/[^"]+)"[\s\S]*?<\/a>/g;
  const res=[]; let m;
  while((m=re.exec(html))){
    const seg=m[0];
    const txt=seg.replace(/<img[^>]*>/g,'').replace(/<svg[\s\S]*?<\/svg>/g,'')
                 .replace(/<[^>]+>/g,'\u0001').split('\u0001').map(s=>s.trim()).filter(Boolean);
    res.push({href:'https://www.daangn.com'+m[1], t:txt.join(' | ')});  // "제목 | 가격 | 동네 | 시간"
  }
  return res;

속도와 차단

CloudFront가 앞단에 있어 너무 빠르면 403이 뜬다. 한 번 막히면 1~2분 쉬어야 풀린다.

  • 안전 구간: 23개 병렬 + 250450ms 간격 (초당 약 2.5~5건). 이 속도로 900개 동을 돌았고 차단 0회
  • 위험 구간: 10병렬 연속. 약 120건에서 막혔다
  • 403이 연속 8건 넘게 나오면 15~20초 쉬고 재개하는 가드를 넣는다
  • page.goto()(브라우저)는 동당 2.4초로 fetch보다 3~4배 느리다. fetch를 쓴다
  • REPL 툴콜은 120초에서 끊긴다. 한 콜에 250~300개 동이 한계이니 나눠 돌린다
  • 에이전트 탭이 중간에 닫혀 page가 null이 되는 일이 있다. fetch 방식이면 영향 없다

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.
