Check whether changed code paths have corresponding tests and suggest minimal coverage.
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
## 既定 CI レビューでは発火しない / Not triggered on the default CI review path このスキルは repo 全体の既存テスト木（変更されていないファイルを含む）を要するため、既定 runner の供給コンテキスト（`RUNNER_SUPPLIED_CONTEXTS = ['diff', 'prDescription', 'fullFile']`、`scripts/validate-skills.mjs`）では発火しない。`RIVER_AVAILABLE_CONTEXTS` を拡張して `tests`（repo-wide test tree）を供給する構成でのみ有効になる（`GRANDFATHERED_UNSUPPLIED_CONTEXT` に登録済み、#1606）。 ## Pattern declaration Primary pattern: Reviewer Secondary patterns: Inversion Why: テスト存在チェックはチェックリスト型評価が主だが、実行パスへ影響するコード変更が差分にない場合は実行を止める必要がある。 ## Goal / 目的 - 差分で挙動が増えたのにテストが追従していないケースを拾い、最小のテスト観点を提案する。 ## Non-goals / 扱わないこと - テストフレームワークの宗教論争（Jest/Vitest など）。 - 網羅的なテストケース列挙（提案は最大3点までに絞る）。 - テスト差分がすでにある場合の追加要求（原則として黙る）。 ## 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。 - [ ] 差分にソースコード（`src/**/*`, `lib/**/*`）またはテストファイル（`*.test.*`, `*.spec.*`）の変更が含まれている - [ ] 実行パスへ影響する変更が差分に含まれている（挙動変更のシグナルが存在する） - [ ] inputContextにdiffが含まれている ゲート不成立時の出力: `NO_REVIEW: test-existence — テスト存在チェックの対象となるコード変更が検出されない` ## False-positive guards / 抑制条件 - 差分にテストファイル（`*.test.*` / `*.spec.*`）が含まれている場合。 ## Rule / ルール - 変更されたコード（関数/メソッド/エンドポイント）に対して対応するテストが存在するか確認する。 - クリティカルパス（認証、課金、データ保存など）にテストが無い場合は優先して補う。 …

How to install
mdr add s977043/river-review/Test Presence for Changed Code@sha256:ea3f1e944b352956The 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.
