CC Version Analysis — Claude Code CLI 버전 영향 분석 워크플로우

CC CLI 버전 업그레이드 시 bkit plugin에 대한 영향을 체계적으로 조사, 분석하고 개선 기회를 도출하는 전문 워크플로우 스킬.

Overview

이 스킬은 CC CLI의 새 버전이 출시되었을 때 다음을 자동화합니다:

1. Phase 1 (Research): CC 변경사항 심층 조사
2. Phase 2 (Analyze): bkit 아키텍처 영향 분석
3. Phase 3 (Brainstorm): Plan Plus 브레인스토밍으로 개선안 도출
4. Phase 4 (Report): 종합 영향 분석 보고서 작성

Agent Team 구성:

• cc-version-researcher: CC 버전 변경사항 외부 조사
• bkit-impact-analyst: bkit 내부 아키텍처 영향 분석
• report-generator: 최종 보고서 생성

HARD-GATE

Do NOT skip any phase. Each phase produces artifacts that feed into the next. Do NOT generate the final report without completing Research and Analysis phases. Do NOT implement any ENH items — this skill is analysis-only. All documents MUST be written in Korean (한국어).

NEW (v2.1.16 errata learning — added 2026-05-20): Do NOT advance from Phase 1 → Phase 2 without completing the Phase 1.5 Raw Source Verification Gate. The cc-version-researcher agent's quantitative claims (bullet count, issue counts, file counts) MUST be cross-checked against ≥2 raw sources (GitHub release tag URL + raw CHANGELOG.md URL) before being adopted into the report. The v2.1.145 cycle leaked an unverified bullet count of 21 (actual: 20) and an unverified agent count of 36 (actual: 34) because this gate did not exist. If raw and agent disagree, raw wins.
