Ensure event-driven designs specify delivery guarantees, ordering, idempotency, schema evolution, and replay/backfill strategy.
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: イベント駆動設計の差分から配信保証・冪等性・スキーマ進化の抜けをレビューし、障害シナリオを逆照射して設計の堅牢性を検証する。 ## Goal / 目的 - イベント駆動設計の差分から、配信保証・順序・冪等性・再処理/リプレイの未定義による事故を減らす。 ## Non-goals / 扱わないこと - メッセージ基盤の選定（Kafka/SQS 等）の是非の断定。 - 実装レベルの consumer コードやライブラリ選定。 ## 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。 - [ ] 差分にイベント駆動・メッセージング・キュー・ストリーム関連のドキュメントまたはスキーマが含まれている - [ ] inputContextにdiffが含まれている ゲート不成立時の出力: `NO_REVIEW: event-driven-semantics — イベント駆動設計関連の差分がない` ## False-positive guards / 抑制条件 - 契約が別ドキュメントで管理され、参照が明確な場合は重複指摘しない。 ## Rule / ルール - 先頭に要約を 1 行出す（新規/変更イベントと consumer 影響の要点）。 - 指摘は最大 8 件まで。順序/重複/再処理で壊れる設計を優先。 - 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 - 配信保証と重複 - 配信保証（at-least-once/at-most-once/exactly-once の前提）が明記されているか。 - 重複配信を前提にした冪等性（idempotency key、dedupe）の設計があるか。 - 順序とキー - 順序保証の前提（partition key、同一キー内のみ順序等）が明示されているか。 - 乱順/遅延到着の扱い（reorder window、最終状態の決め方）があるか。 - スキーマ進化 - 互換性ルール（追加は後方互換、削除は破壊的等）と versioning があるか。 - deprecated 期間と移行手順（producer/consumer の段階更新）があるか。 - 再処理/リプレイ - リプレイ/backfill の方針（いつ、どこから、どれくらい）があるか。 - DLQ/poison message の扱いと再処理手順があるか。 - 観測性 …

How to install
mdr add s977043/river-review/Event-Driven Semantics & Delivery Guarantees@sha256:c0b43361d7b08561The 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.
