Minimal always-on sample skill to guarantee an end-to-end review experience.
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: 最小構成のサンプルスキルとしてほぼ常に選択されるが、差分が存在しない場合は実行不要 ## Guidance このスキルは「最小構成でも必ず 1 つスキルが選ばれる」ことを目的としたサンプルです。 - 変更差分が存在する限り、ほぼ全てのリポジトリで選択されます（`applyTo: '**/*'`）。 - 実運用では、より具体的な `applyTo` と `inputContext` を設定し、指摘の粒度を上げてください。 ## 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。 - [ ] 差分が空でない（1行以上の変更がある） - [ ] inputContextにdiffが含まれている ゲート不成立時の出力: `NO_REVIEW: hello-skill — レビュー対象の差分が存在しない` ## 評価指標（Evaluation） - 合格基準: 指摘が差分に紐づき、根拠と次アクションが説明されている。 - 不合格基準: 差分と無関係な指摘、根拠のない断定、抑制条件の無視。 ## 人間に返す条件（Human Handoff） - 仕様や意図が不明確で解釈が分かれる場合は質問として返す。 - 影響範囲が広い設計判断やトレードオフは人間レビューへ返す。

How to install
mdr add s977043/river-review/Hello Skill (Always-On Sample)@sha256:54171e5cce556b0cThe 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.
