Cross-File Leakage リファクタ後の caller 側残骸検出 SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

Cross-File Leakage リファクタ後の caller 側残骸検出 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/Cross-File Leakage リファクタ後の caller 側残骸検出@v0.1.0

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

モジュール/スキルの構造変更で当該ファイルは更新したが、caller 側が古い構造(旧参照・旧シグネチャ・旧採番)を参照したまま残るパターンを検出する.

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: 構造変更に対する caller 走査は grep による決定論的突合が主だが、構造変更を含まない変更では実行を止めるゲートが必要

## Goal / 目的

- スキル/モジュールを構造変更したとき、**当該ファイルは更新したが caller 側 N 箇所が古い構造を参照したまま** 残るパターンを検出する。
- 「変更元は直したが、参照元を直し忘れた」ドリフトを、変更の波及範囲を grep で追って可視化する。

## Non-goals / 扱わないこと

- 構造変更そのものの良し悪しの判断。
- 静的型エラーの検出(型システムが捕捉できる drift はコンパイラ/tsc の役割)。
- 当該ファイル内の整合性(それは `self-contradiction` の領域)。

## 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。

- [ ] 差分に構造変更(記号の再採番、シンボル名変更、シグネチャ変更、セクション番号の振り直し、ファイル分割・移動)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: cross-file-leakage — 構造変更が検出されない`

## False-positive guards / 抑制条件

- 旧構造への参照を grep しても caller 側に残骸が見つからない場合は指摘しない。
- 残骸が意図的(旧 API の互換 shim、移行期間中の dual-reference)で差分内に明記がある場合は抑制。
- 参照が文字列として同一でも別シンボル/別スコープを指す場合は抑制。

## Rule / ルール

### 検出ロジック

1. **構造変更の特定**: 差分から「何がどう変わったか」を抽出する(旧シンボル→新シンボル、`§2.1`→新採番、`foo(a)`→`foo(a, b)`、ファイル A→分割後)。
2. **caller の列挙**: 旧構造の識別子(旧シンボル名・旧参照形式・旧パス)を repo 全体に grep し、参照している全箇所を列挙する。
3. **残骸の判定**: 列挙した参照のうち、今回の差分で更新されていないものを残骸として特定する。
4. **波及の報告**: 残骸を `<file>:<line>` と検索語で示し、更新漏れの caller を網羅的に挙げる。

How to install

The exact contents, by fingerprint
mdr add s977043/river-review/Cross-File Leakage リファクタ後の caller 側残骸検出@sha256:bcb807b500ed642e

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.
