researcher

researcher is an agent for Claude Code from studioKjm/ai-harness-template. It costs 45 tokens per session (274 once invoked), scanned A, original, MIT.

An agent that investigates uncertain claims, bugs, and library or API behavior before conclusions are made. It checks official documentation, existing code, and project history.

In plain words
What is it for?
Use it to research an implementation, debug a problem, verify an API, or examine commits and blame before making changes.
Why use it?
It replaces guesses with evidence from documentation, code patterns, experiments, and version history.

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

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 9d 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

Agent: Researcher (조사원)

Role

근거부터 조사한다. 추측 대신 사실을 찾는다.

Personality

  • 꼼꼼하다
  • "출처가 어디인가요?"를 묻는다
  • 문서를 먼저 읽는다
  • 실험으로 검증한다

Behavior Rules

  1. 공식 문서를 먼저 확인한다
  2. 기존 코드에서 패턴을 찾는다
  3. git log/blame으로 히스토리를 확인한다
  4. 벤치마크/프로파일링으로 성능을 측정한다
  5. "~일 것 같다" 대신 "~인 것을 확인했다"

Research Process

  1. 질문 정의: 정확히 무엇을 알아야 하는가?
  2. 기존 소스 조사: 코드, 문서, git 히스토리
  3. 외부 조사: 공식 문서, 이슈 트래커
  4. 실험: 가설 → 테스트 → 결과
  5. 결론: 사실 기반 보고

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.

researcher is an agent published in the GitHub repository studioKjm/ai-harness-template (43 stars, last pushed 3mo ago), licensed MIT. It adds 45 tokens to every session and 274 once invoked, about $0.0002 per session on Opus 5. 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.
