data-explorer

data-explorer is a skill for Claude Code from modu-ai/moai-cowork. It costs 97 tokens per session (651 once invoked), scanned A, original, Apache-2.0.

A profiling and quality check for CSV or Excel files that summarizes columns, missing data, unusual values, duplicates, data types, and relationships between numbers.

In plain words
What is it for?
Use it to inspect a dataset before analysis, find missing or extreme values, check duplicates, understand distributions, and identify strong correlations.
Why use it?
It turns a raw spreadsheet into a report that shows what the data contains and where it may be incomplete, inconsistent, or suspicious.

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

data-explorer 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

데이터 탐색기 (Data Explorer)

역할

CSV/Excel 파일을 받아 데이터 프로파일링, 품질 검사, 기초 분석을 수행하는 전문가.

워크플로우

Step 1: 데이터 로딩

  • 파일 형식 감지 (CSV, XLSX, TSV)
  • 인코딩 자동 감지 (UTF-8, CP949, EUC-KR)
  • 행/열 수, 데이터 타입 추론

Step 2: 프로파일링

  • 각 컬럼별: 타입, 유니크 수, 결측률, 최소/최대/평균/중앙값
  • 범주형 컬럼: 상위 5개 빈도
  • 수치형 컬럼: 분포 요약 (왜도, 첨도)

Step 3: 품질 검사

  • 결측값 패턴 (MCAR/MAR/MNAR 추론)
  • 이상값 탐지 (IQR 방법, Z-score)
  • 중복 행 식별
  • 데이터 타입 불일치

Step 4: 상관관계 분석

  • 수치 컬럼 간 피어슨/스피어만 상관계수
  • 높은 상관(|r| > 0.7) 하이라이트
  • 범주-수치 간 관계 (ANOVA F-test)

Step 5: 인사이트 + 분석 방향 제안

  • 핵심 발견 3가지 요약
  • 분석 방향 3가지 제안 (AskUserQuestion)

산출물

  • 데이터 프로파일 보고서 (마크다운)
  • 품질 점수 (0-100)
  • 분석 방향 추천

도구 사용

  • Bash: Python pandas 스크립트 실행 (프로파일링)
  • Read: CSV/Excel 파일 직접 읽기
  • 시각화 필요 시: moai-analyst:data-visualizer로 연계

이 스킬을 사용하지 말아야 할 때

  • 차트/그래프 생성 → moai-analyst:data-visualizer 사용
  • 공공데이터 조회 → moai-analyst:data-public 사용
  • PPT/Word 변환 → moai-coworker 플러그인 사용

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
