スキーマ/データ移行の安全性を framework 非依存で審査する。破壊的スキーマ変更・ロック誘発・backfill・ロールバック可逆性・expand-contract の段階適用を、prisma / typeorm / Rails / Django / Alembic / 生 SQL などに横断適用する。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Pattern declaration Primary pattern: Reviewer Secondary patterns: Inversion Why: 移行の破壊的・ロック誘発・不可逆操作をチェックリスト型で検査するが、移行を含まない差分では実行を止めるゲートが必要。 ## Goal / 目的 - ORM やフレームワークに依存せず、スキーマ/データ移行に共通する**運用事故**（データ損失・本番ロック・ロールバック不能・反復不能）を検出する。 - 特定フレームワーク固有の深い規約（例: Laravel `change()` の修飾子消失）は専用 skill に委ね、本 skill は**横断的な安全性**に集中する。 ## Non-goals / 扱わないこと - データモデル設計の妥当性（正規化・関連設計）は `data-model-db-design` のスコープ。 - フレームワーク固有の細則（Laravel 固有は `laravel-migration-safety`）。 - アプリ側のクエリ効率（N+1 等）。 ## Pre-execution Gate / 実行前ゲート このスキルは以下の条件がすべて満たされない限り `NO_REVIEW` を返す。 - [ ] 差分にスキーマ/データ移行（migrations ディレクトリ・`schema.prisma`・`*.sql`・`ALTER`/`CREATE`/`DROP` を含む変更）が含まれている - [ ] diff コンテキストが利用可能である ゲート不成立時の出力: `NO_REVIEW: migration-safety — 移行の変更なし` ## False-positive guards / 抑制条件 - 新規テーブル作成内の index/制約追加は既存行へのロックが無いため指摘しない。 - 不可逆な down/rollback は、データ変換系移行で完全な逆操作が原理的に不可能なケースが正当（コメントで明示があれば許容）。 - 破壊的操作が「別 PR で deprecate 済み／expand-contract の contract フェーズ」と明示されている場合は指摘しない。 - 小規模テーブルが diff／文脈から確実な場合はロック懸念を断定しない（`questions` で確認）。 ## Rule / ルール 横断的に以下を確認する（該当するもののみ）: 1. **破壊的スキーマ変更**: カラム/テーブル/制約の DROP、型の縮小変換（例: `text`→`varchar(n)`）、リネームは、データ損失と後方互換を確認する。 …

How to install
mdr add s977043/river-review/Migration Safety Review (framework-agnostic)@sha256:37b22848753e86c1The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
