Ensure designs define data flow, state ownership, consistency boundaries, and cross-boundary writes to prevent drift and incidents.
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: データフローと状態所有の曖昧さをチェックリスト型で評価し、整合性崩れや二重書き込みを事前に検出する ## Goal / 目的 - 設計の差分から、データフロー/状態所有の曖昧さによる整合性崩れ・二重書き込み・障害時の復旧困難を減らす。 ## Non-goals / 扱わないこと - 分散システムの一般論を長々と語らない(差分に紐づく具体的な曖昧さに限定)。 - 実装レベルの最適化(キュー設定や DB チューニングなど)。 ## 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。 - [ ] 差分に設計ドキュメント(フロー図/シーケンス図/データフロー設計書)の変更がある - [ ] 差分にデータフロー・状態所有・境界横断の書き込みに関わる記述の追加または変更がある - [ ] inputContextにdiffが含まれている ゲート不成立時の出力: `NO_REVIEW: data-flow-state-ownership — データフロー・状態所有に関わる変更が検出されない` ## False-positive guards / 抑制条件 - PoC/運用対象外と明記されている場合は、強度を落として “確認事項” に倒す。 ## Rule / ルール - 先頭に要約を 1 行出す(追加/変更されたデータフローと所有の要点)。 - 指摘は最大 8 件まで。整合性・二重書き込み・競合・障害復旧に直結するものを優先。 - 可能なら “追記テンプレ” を付ける(文書に貼れる形)。 ## Checklist / 観点チェックリスト - 状態所有(Source of Truth) - 主要エンティティ/状態の SoT(誰が唯一の真実か)が明示されているか。 - 同じ状態を複数の境界で更新しない設計になっているか(必要なら理由とガードがあるか)。 - 境界横断の書き込み - どの境界からどの境界へ “書く” のか、同期/非同期、順序保証の前提があるか。 - 二重実行/重複配信への対策(冪等性キー、upsert、dedupe)が設計にあるか。 - 整合性と競合 - 強整合/最終整合の選択と、ユーザー体験への影響が説明されているか。 - 競合(同時更新)の扱い(楽観ロック、解決戦略、再試行方針)があるか。 - 監査と追跡 - 重要イベントの監査ログ、相関ID など、追跡可能性の前提があるか。 - リカバリ …

How to install
mdr add s977043/river-review/Data Flow & State Ownership@sha256:fc9912d52df48cf9The 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.
