Existing-Pattern Conformance 既存パターン準拠の確認 SKILL.md skillA

Existing-Pattern Conformance 既存パターン準拠の確認 from s977043/river-review is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add s977043/river-review/Existing-Pattern Conformance 既存パターン準拠の確認@v0.1.0

Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

新実装が、同種の先行実装(同レイヤ・同責務・同概念)に在る防御 / バリデーション / エラー処理 / 規約 / 共通化ロジック / 概念定義を、欠落・重複・食い違いなく継承しているかを grep で先行特定して確認する.

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: 先行実装との突合は grep による決定論的特定が主だが、同種の先行実装が存在しない新規領域では実行を止めるゲートが必要。

## Goal / 目的

- 新しい追加 / 変更が、**同種の先行実装をまず grep で特定**し、そこに在る防御・バリデーション・エラー処理・定数 / 規約・共通化ロジック・概念定義を**欠落・重複・食い違いなく継承**しているかを確認する。
- 「既存に同じことをする実装があるのに、それを参照せず独自に書いて防御やバリデーションが抜けた / 重複した / 規約から外れた」パターンを検出する。

外部実証: [「CodeGraph(AI向け効率化ツール)は「間接呼び出しの見落とし」を防ぐ。でも、自分たちのレビューが長引いた原因はそれじゃなかった」](https://zenn.dev/thegatebreaker/articles/codegraph_trial_review_gap)(TheGateBreaker, 2026-07-30)は、重複ロジック 4 箇所に対するコールグラフツールの適用結果を報告します。検出できたのは中心関数を直接呼び出していた 2 箇所のみでした。残る 2 箇所は同じ判定条件をそれぞれの場所で独立に再実装しており、呼び出し関係が無いためコールグラフ上では中心関数とつながっていませんでした。著者は間接呼び出しの見落としと独立した重複を別の障害モードと位置づけ、重複が疑われる場合はまず grep で確認する従来手順を維持しています。この実測は、先行実装を grep で特定してから突合するという本スキルの検出ロジックを裏付ける一次データとして参照できます。

## Non-goals / 扱わないこと

- 設計の良し悪しそのもの(既存が間違っていれば従う必要はない。意図的差分は根拠の明文で許容)。
- リファクタ後の caller 残骸(`cross-file-leakage` の領域)。
- 宣言と実装の自己矛盾(`self-contradiction` の領域)。

## Pre-execution Gate / 実行前ゲート

How to install

The exact contents, by fingerprint
mdr add s977043/river-review/Existing-Pattern Conformance 既存パターン準拠の確認@sha256:ee8efff6d6b5d141

The 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.
