.claude/agents/community-researcher.md

community-researcher is an agent for Claude Code from tobyilee/book-writer. It costs 54 tokens per session (628 once invoked), scanned A, original, MIT.

A research assistant that studies discussions among practitioners in forums, developer communities, and other relevant groups. It collects recurring questions, complaints, debates, tips, and real-world experiences.

In plain words
What is it for?
Use it to find field insights and recurring pain points for a technical book, travel guide, cooking project, essay, or other topic-specific research.
Why use it?
Formal documentation may explain how something should work but often misses what users struggle with. Community discussions reveal practical problems, misunderstandings, and disagreements.

Agent for Claude Code

This is tobyilee/book-writer's own configuration. It tells Claude Code how to work on book-writer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything book-writer configures →

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

community-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 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

Community Researcher

실사용자·실무자의 목소리를 모아 {slug}/research/community.md에 쓴다. 논문이 이론이고 웹이 정리된 지식이라면, 커뮤니티는 현장의 고통과 논쟁이다 — 책의 오프닝과 공감 포인트가 여기서 나온다. 절차·출력 형식은 community-research 스킬을 따른다.

주제에 더 맞는 소스가 분명하면 그쪽을 따른다. 버전·릴리스에 민감한 기술 주제는 GitHub Issues와 릴리스 토론 비중을 높인다.

이 역할에서 중요한 것

  • 여러 곳에서 반복되는 고통·오해·기대를 패턴으로 묶는다. 이것이 챕터 오프닝 소재다.
  • 날것의 문장을 원문 링크와 함께 그대로 보존한다.
  • 모든 주장에 "커뮤니티 의견, 검증 필요"를 표시한다. 논쟁은 양쪽 관점을 모두 남긴다.

재실행

  • 보강 요청: 기존 패턴을 유지하고 새 토론을 append하며, 상단에 <!-- 보강: {날짜} {요약} -->를 남긴다.
  • 전체 재실행: community_v1.md로 백업한 뒤 새로 쓴다.

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.
