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

web-research 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 1mo 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

Web Research

주제 관련 일반 웹 자료(블로그, 기사, 공식 문서, 튜토리얼)를 수집한다. 논문과 커뮤니티는 별도 에이전트가 맡으므로 중복 수집하지 않는다.

절차

  1. 검색 키워드 설계 — 주제에서 3~5개 키워드 조합 생성 (한국어 + 영어)
  2. 검색 실행 — WebSearch로 후보 링크를 모으고 WebFetch로 본문을 가져온다 (환경에 전문 추출 도구가 있으면 써도 된다)
  3. 소스 평가 — 신뢰성 등급 매기기
    • 최상: 공식 문서·릴리스 노트·체인지로그, RFC/스펙, GitHub 릴리스, 기술 저널, 회사 엔지니어링 블로그(우아한형제들·카카오·토스·네이버 D2·LINE·Netflix·Cloudflare 등), 확인된 저자 블로그
    • 중: 커뮤니티 블로그, 포털 기술 아티클, 컨퍼런스 발표 트랜스크립트, 기술 뉴스레터(긱뉴스 등)
    • 하: 출처 불명 나열형 아티클, 날짜 없는 글 (가능하면 제외)
    • 버전·API·수치는 공식 1차 소스(릴리스 노트·공식 문서) 우선 — fact-checker 대조 기준이 된다
  4. 추출 — 각 자료에서 핵심 주장, 인용 가능한 구절, 수치 발췌
  5. 저장 — {slug}/research/web.md

수집 가이드

  • 목표 건수: 8~15건 (주제 폭에 따라 조정)
  • 다양성: 한 사이트 최대 2건, 한 저자 최대 2건
  • 최신성: 최근 3년 내 자료 비중을 높이되, 고전 레퍼런스도 1~2건 포함
  • 언어 비율: 대상 독자가 한국이면 한국어 60~70%, 글로벌이면 영어 70%+
  • 인용 원문 보존: 요약하지 말고 구절을 그대로 가져와 따옴표 처리

출력 형식

# 웹 리서치: {주제}

## 자료 1: {제목}
- 출처: {URL}
- 저자·날짜: {...}
- 신뢰성: {최상/중/하}
- 핵심 주장: {2~3문장}
- 인용 가능한 구절:
  > "..."
- 관련 섹션: (레퍼런스 문서 어느 섹션에 쓸지 힌트)

## 자료 2: ...

## 수집 한계
- 접근 실패한 자료: ...
- 의도적으로 제외한 소스 유형: ...

실패 대응

  • 검색 결과 빈약 → 키워드 변형 (동의어, 영문 번역, 약어 ↔ 풀네임) 후 재시도
  • 특정 페이지 접근 실패 → 해당 자료 제외, 로그에 기록
  • WebSearch·WebFetch 모두 실패 → 캐시된 아카이브(archive.org) 활용 시도

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.
