Self-Contradiction Detector 自己矛盾検出 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.

Self-Contradiction Detector 自己矛盾検出 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/Self-Contradiction Detector 自己矛盾検出@v0.1.0

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

同一ファイル/隣接ファイル内で「規則Xを守れ」と宣言した直後にXを破っている、宣言と実装の乖離を検出する.

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: 宣言(declarative phrase)と実装の突合はチェックリスト型だが、宣言が差分に存在しない変更では実行を止めるゲートが必要

## Goal / 目的

- ファイル/スキル/ドキュメントが「規則 X を守れ」と宣言した直後・同じファイル内で **規則 X を破っている** パターンを検出する。
- Pre-mortem(失敗シナリオ)や Logic Torturing(論理の穴)では捉えにくい、**「宣言」と「実装」の乖離** に特化する。

## Non-goals / 扱わないこと

- 個別の論理的整合性の検証(`logic-torturing` の役割)。
- 攻撃経路の分析(`war-game` の役割)。
- 規則そのものの妥当性判断(規則が正しいか否かではなく、宣言と実装が一致するかを見る)。

## 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。

- [ ] 差分に宣言的フレーズ(「〜しない」「禁止」「必ず〜する」「don't」「never」「MUST」「always」等)が含まれている、またはそれを含む既存ファイルへの変更である
- [ ] inputContext に diff または fullFile が含まれている

ゲート不成立時の出力: `NO_REVIEW: self-contradiction — 宣言的フレーズが検出されない`

## False-positive guards / 抑制条件

- 宣言が「例外を明示している」場合(「ただし X の場合を除く」)で、実装がその例外条件に該当するなら抑制。
- 宣言がコメントアウトされた旧仕様や、引用ブロック(「悪い例」として提示されたコード)の場合は抑制。
- 宣言と実装が別の対象を指している(同名だがスコープが異なる)場合は抑制。

## Rule / ルール

### 検出ロジック

1. **宣言の抽出**: 差分・対象ファイルから declarative phrase を抽出する。
   - 禁止形: 「〜しない」「〜してはいけない」「禁止」「避ける」「don't」「never」「avoid」「MUST NOT」
   - 義務形: 「必ず〜する」「〜すること」「MUST」「always」「required」
2. **対象の特定**: 各宣言が何を規律しているか(参照形式・命名・依存方向・出力形式等)を1文で言語化する。

How to install

The exact contents, by fingerprint
mdr add s977043/river-review/Self-Contradiction Detector 自己矛盾検出@sha256:61d2818031b7ca4a

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.
