[chore] Data 로컬 에이전트 및 리뷰 체계 도입

[You-Hyuk]

관련 이슈

Closes #86

---

변경 개요

CLAUDE.md에 설명으로만 있던 "Agent A/B" 병렬 패턴을 담당 범위가 고정된 로컬 에이전트로 옮기고, CLAUDE.md 코딩 규칙을 검사하는 data-review 스킬과 시크릿 파일 쓰기 차단 훅을 추가해 Backend 수준의 실행형 리뷰 체계를 갖춘다. 작업 중 발견한 문서·코드 불일치(릴리즈 수집 소스, 크론 시각, CLI 플래그)도 함께 정정한다.

변경사항

파일	변경 내용
.claude/settings.json	Write/Edit 대상 경로에 .env·.secret·credentials가 포함되면 거부하는 PreToolUse 훅 추가
.claude/agents/data-implementer.md	구현 에이전트 — collectors/·matchers/·db/·notifier/ 담당, tests/ 수정 금지
.claude/agents/write-tests.md	테스트 에이전트 — tests/만 담당, patch 경로·time.sleep 무력화 등 컨벤션 명시
.claude/skills/data-review/	DML-only·print 금지·Python 3.9 문법·rate limit·패키지 등록 체크리스트 (grep 자동 검사 + 수동 검토)
CLAUDE.md	병렬 실행 임계치·커밋 전 체크리스트 추가, 외부 API 표·CLI 플래그를 코드 기준으로 정정
docs/pipeline.md	릴리즈 수집을 Spotify 기준으로 재작성, KOPIS 잡 시각 00:00/00:30 정정
README.md	코드와 어긋난 내용 정정 + "AI 협업 워크플로우" 섹션 추가

주요 구현 내용

• 병렬 실행 임계치: 새 public 함수 추가, 구현 파일 2개 이상 수정, 새 테스트 파일 필요 중 하나라도 해당하면 data-implementer ∥ write-tests 병렬 실행. 두 에이전트의 수정 가능 디렉터리가 겹치지 않아 충돌이 없다.
• ruff가 못 잡는 3.9 문법: pyproject.toml의 ruff target-version이 py311이라 X | Y·match가 린트로 잡히지 않는다. data-review에서 grep으로 별도 검사한다. 위반을 일부러 넣은 파일로 DDL·print·X | None·match를 모두 잡는 것을 확인했고, 레포 전체 오탐은 정규식 문자열 1건(musicbrainz.py:42)이다.
• 문서 정정: 릴리즈 수집이 Spotify로 이전돼 Cover Art Archive·MusicBrainz release 엔드포인트 호출부가 없는데 문서에 남아 있어, 에이전트 규칙까지 같이 정정했다.

---

테스트

• 훅 동작 확인 — .env·.envrc·credentials.json 경로는 deny, collectors/*.py는 통과
• data-review 자동 검사식 검증 (위반 파일 탐지 + 레포 오탐 확인)
• 단위 테스트 추가/수정 — Python 코드 변경 없음
• 새 세션에서 두 로컬 에이전트 실제 호출 확인

---

리뷰어 참고사항

• /issue·/plan-issue·/commit·/pr은 전역 스킬이라 레포에 포함되지 않는다 (README에 명시).
• ruff target-version을 py39로 내리는 건 기존 코드에 새 경고가 뜰 수 있어 이번 범위에서 제외했다.

---

코드 리뷰

변경사항 요약

설정·에이전트·스킬·문서만 변경 (Python 코드 변경 없음). .claude/settings.json 훅 추가, 로컬 에이전트 2개·data-review 스킬 신설, CLAUDE.md·README·pipeline.md 정정.

검토 결과

🟡 warning

• .claude/settings.json: 차단 훅이 Write/Edit만 검사해 Bash(echo > .env 등)로 쓰는 경로는 막지 못한다 (Backend와 동일한 한계)
  → 필요하면 Bash matcher에 리다이렉트 대상 검사를 추가하거나 permissions.deny로 보완

🔵 suggestion

• pyproject.toml: ruff target-version = "py311"이 런타임(3.9)과 불일치
  → 별도 이슈로 py39 전환 검토 (적용 시 data-review의 3.9 문법 grep 검사 축소 가능)
• .claude/skills/data-review/SKILL.md: 검토 범위를 git merge-base HEAD origin/main으로 잡아 origin/main이 오래되면 범위가 넓어질 수 있다
  → 실행 전 git fetch 단계 추가 검토
• .claude/settings.json: 더 이상 쓰지 않는 WebFetch(domain:coverartarchive.org) 권한이 남아 있다
  → 정리 시 제거

Summary by CodeRabbit

• Documentation

📝 Walkthrough

Walkthrough

The changes add local agent definitions, data-review checks, and secret-file write protection. They also update repository and pipeline documentation for Spotify release collection, schedules, commands, and environment settings.

Changes

Local agent and review workflow

Layer / File(s)	Summary
Implementation and test agent roles .claude/agents/data-implementer.md, .claude/agents/write-tests.md	The agent definitions specify implementation and test scopes, constraints, validation steps, and reporting requirements.
Review checklist and file protection .claude/skills/data-review/SKILL.md, .claude/skills/data-review/references/data-checklist.md, .claude/settings.json	The skill and checklist define data-code review checks and reporting. A hook denies writes to paths containing .env, .secret, or credentials.
Repository workflow instructions CLAUDE.md, README.md	The workflow documentation describes agent roles, parallel execution criteria, review checks, and Claude Code steps.

Pipeline source and operation documentation

Layer / File(s)	Summary
Spotify release collection documentation CLAUDE.md, README.md, docs/pipeline.md	The repository and API descriptions identify Spotify as the release source. The pipeline documentation describes album retrieval, filtering, and persistence rules.
Schedule and command documentation CLAUDE.md, README.md	The documentation updates concert task times, initialization and recovery options, single-item collection commands, and API environment settings.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🟡 Moderate · up to 231ec

The new workflow can miss secret-file writes and approve an untracked Python file without reviewing its contents. These safeguards should be corrected before merge; the edited-test hook also falls short of its documented behavior.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 231ec

Delegated coding work can use shell commands despite written file restrictions, while the new secret-file protection covers only direct edit operations. Exposure appears local, and shell access already existed, but the new delegation makes the boundary worth reviewing.

Retained concerns

• Low · security · inferred: The new implementation role delegates Bash authority, while its secret-file and directory restrictions are written instructions; shell writes do not pass through the new Write/Edit secret-path check. This creates an independently delegated route to files writable by the local session, although the underlying shell permission predates the PR.

Security review details

Security Blast Radius

• inferred — A Bash write is outside this hook's matcher. The independently reachable scope is bounded by the local session's effective filesystem permissions, not by the role's written directory list; repository evidence does not establish that outer bound.

Security Findings and Attack Paths

• inferred — If delegated work invokes Bash to write a secret file, the Write/Edit hook does not inspect that operation. Bash permission and this route existed before the PR; the relevant change is delegation of Bash to the new local role. No external attacker entrypoint or cross-service reachability is established.

Trust Boundaries and Controls

• observed — The hook checks literal path text for .env, .secret, or credentials. Its source contains no path canonicalization or symlink-target check; whether the runtime normalizes paths before delivery remains unknown.

Resilience and Maintainability Implications

• inferred — Written role restrictions and the tool-specific hook may drift apart as more file-writing routes are used; neither the available configuration nor documentation establishes a common enforcement boundary.

Hardening Proposals

• proposed — If secret-file protection is intended across all delegated work, enforce it at a boundary that also governs shell writes, and verify both ordinary and aliased paths in a fresh session.

Explanation

The PR also changes README and docs/pipeline.md to document a Spotify release-source migration and changes the collection schedule. It adds unrelated CLI, API, and recovery documentation updates. These changes do not implement the local-agent, review-skill, secret-hook, or CLAUDE.md workflow objectives in issue #86.

Inline comments:
In @.claude/settings.json:
- Around line 29-33: Extend the secret-file safeguard beyond the Write|Edit
matcher so Bash commands that write to protected paths are also denied; enforce
the same protected-path check through a Bash-aware hook or a mechanism that
applies regardless of tool, including when permissions are bypassed.

In @.claude/skills/data-review/SKILL.md:
- Around line 19-20: Update the review flow that uses git ls-files and git diff
so it also reads the contents of each untracked Python file listed as a review
target; keep the existing diff-based checks for tracked files.

In `@README.md`:
- Line 223: Update the README PostToolUse description to match the hook’s actual
test mapping: clarify that automatic test execution applies to Python source
edits with a corresponding mapped test, or otherwise accurately describe how
test-file edits are handled. Do not claim that editing tests/test_foo.py runs
that same test when the hook prefixes its basename with test_.
