History Insight

Claude Code 세션 히스토리를 분석하고 인사이트를 추출합니다.

Data Location

~/.claude/projects/<encoded-cwd>/*.jsonl

Path Encoding: /Users/foo/project → -Users-foo-project

상세 파일 포맷: ${baseDir}/references/session-file-format.md

Execution Algorithm

Step 1: Ask Scope [MANDATORY]

스코프 결정:

명시된 경우 (AskUserQuestion 생략 가능):

  • "현재 프로젝트만" / "이 프로젝트" → current_project

  • "모든 세션" / "전체" → all_sessions

명시되지 않은 경우 - AskUserQuestion 호출:

question: "세션 검색 범위를 선택하세요" options:

  • "현재 프로젝트만" → ~/.claude/projects/<encoded-cwd>/*.jsonl
  • "모든 Claude Code 세션" → ~/.claude/projects/**/*.jsonl

Step 2: Find Session Files

Current project only

find ~/.claude/projects/<encoded-cwd> -name "*.jsonl" -type f

All sessions (모든 프로젝트)

find ~/.claude/projects -name "*.jsonl" -type f

날짜 필터링: 파일의 mtime(수정시간) 확인 후 필터. OS별 stat 옵션 다름:

  • macOS: stat -f "%Sm" -t "%Y-%m-%d" <file>

  • Linux: stat -c "%y" <file>

Step 3: Process Sessions

Decision Tree

Session files found? ├─ No → Error: "No sessions found" └─ Yes → How many files? ├─ 1-3 files → Direct Read + parse └─ 4+ files → Batch Extract Pipeline

1-3 Files

직접 Read로 JSONL 파싱. 파일이 크면(≥5000 tokens) extract-session.sh 사용:

${baseDir}/scripts/extract-session.sh <session.jsonl>

4+ Files: Batch Extract Pipeline

  • 캐시 디렉토리 생성 (/tmp/cc-cache/<analysis-name>/ )

  • 세션 목록 저장 (sessions.txt )

  • jq로 메시지 일괄 추출 (user_messages.txt )

  • 정리 및 필터링 (clean_messages.txt )

  • Task(opus)로 종합 분석

파일이 너무 클 때: 병렬 배치 분석

clean_messages.txt 가 너무 커서 Read 실패 시:

파일 분할:

split -l 2000 clean_messages.txt /tmp/cc-cache/<name>/batch_

병렬 Task(opus) 호출:

Task(subagent_type="general-purpose", model="opus", run_in_background=true) prompt: "batch_XX 파일을 읽고 주제/패턴 요약해줘"

결과 병합: Task(opus)로 종합

Step 4: Report Results

Session Capture Complete

  • Sessions: N files processed
  • Messages: X total, Y after filter

Error Handling

Scenario Response

No session files found "No session files found for this project."

File too large Auto-preprocess with extract-session.sh

jq not installed "Error: jq is required. Install with: brew install jq"

Task failed "Warning: Could not process [file]. Skipping."

0 relevant sessions "No sessions matched your criteria."
