Claude Code 세션 transcript(~/.claude/projects)의 토큰 사용을 집계해 비용 방정식 항 (요청/턴, 요청당 컨텍스트, prefix cache 재구축 원인, 도구 출력 크기, subagent 모델, effort)과 anti-pattern flag로 보고하는 스킬. "세션 비용 분석", "토큰 어디서 새", "이 프로젝트 토큰 왜 많이 써", "컨텍스트가 왜 이렇게 커", "캐시 미스 확인", "prompt cache 효율 봐줘", "subagent 모델 뭐 썼어", "compaction 안 되는데", "cost dashboard", "session cost audit", "token usage breakdown", "where do my tokens go", "context bloat check" 등에서 트리거.
