このスキルを使用して、デプロイメント、マージ、または依存関係アップグレード後にデプロイされたURLの回帰を監視します。.

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

# カナリアウォッチ — デプロイ後の監視

## 使用時期

- 本番またはステージングへのデプロイ後
- 危険なPRをマージした後
- 修正が実際に修正されたことを確認したい場合
- ローンチウィンドウ中の継続的監視
- 依存関係アップグレード後

## 動作方法

デプロイされたURLの回帰を監視します。停止されるか監視ウィンドウが期限切れになるまで、ループで実行されます。

### 監視内容

```
1. HTTPステータス — ページは200を返していますか?
2. コンソールエラー — 以前なかった新しいエラーはありますか?
3. ネットワークの障害 — 失敗したAPIコール、5xx応答?
4. パフォーマンス — LCP/CLS/INPの回帰対ベースライン?
5. コンテンツ — 主要な要素は消えましたか?(h1、nav、footer、CTA)
6. API健康 — 重要なエンドポイントはSLA内で応答していますか?
```

### 監視モード

**クイックチェック**(デフォルト):シングルパス、レポート結果
```
/canary-watch https://myapp.com
```

**継続監視**:N分ごとにM時間チェック
```
/canary-watch https://myapp.com --interval 5m --duration 2h
```

**差分モード**:ステージング対本番を比較
```
/canary-watch --compare https://staging.myapp.com https://myapp.com
```

### 警告しきい値

```yaml
critical:  # 即座の警告
  - HTTPステータス != 200
  - コンソールエラー数 > 5(新しいエラーのみ)
  - LCP > 4s
  - APIエンドポイントは5xxを返す

warning:   # レポートで報告
  - LCP ベースラインから > 500ms増加
  - CLS > 0.1
  - 新しいコンソール警告
  - レスポンス時間 > 2xベースライン

info:      # ログのみ
  - マイナーパフォーマンス分散
  - 新しいネットワークリクエスト(サードパーティスクリプトが追加された?)
```

### 通知

重大なしきい値を超えたとき:
- デスクトップ通知(macOS/Linux)
- オプション:Slack/Discord Webhook
- `~/.claude/canary-watch.log`にログ

How to install

The exact contents, by fingerprint
mdr add affaan-m/ecc/canary-watch@sha256:603f9838927c1b2b

The line at the top of this page pins the label git:20260517.ec9ace9, 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.
