ローカルのコスト追跡データベースからClaude Codeのトークン使用量、支出、予算を追跡・レポートします。コスト、支出、使用量、トークン、予算、またはプロジェクト、ツール、セッション、日付によるコスト内訳について質問する場合に使用します。.

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

# コスト追跡

このスキルを使用して、ローカルSQLiteデータベースからClaude Codeのコストと使用履歴を分析します。これは、`~/.claude-cost-tracker/usage.db`に使用行を書き込むコスト追跡フックまたはプラグインをすでに持っているユーザーを対象としています。

出典: `MayurBhavsar`によるコミュニティのPR #1304から救済されました。

## 使用時期

- ユーザーが「いくら使いましたか?」「このセッションのコストは?」「トークン使用量は?」と尋ねる場合
- ユーザーが予算、支出制限、超過、またはコスト管理について言及する場合
- ユーザーがプロジェクト、ツール、セッション、モデル、または日付ごとのコスト内訳を求める場合
- ユーザーが今日と昨日を比較したい、または最近のトレンドを確認したい場合
- ユーザーが最近の使用記録のCSVエクスポートを求める場合

## 動作方法

まず前提条件を確認します:

```bash
command -v sqlite3 >/dev/null && echo "sqlite3 available" || echo "sqlite3 missing"
test -f ~/.claude-cost-tracker/usage.db && echo "Database found" || echo "Database not found"
```

データベースが見つからない場合、使用データを作成しません。ユーザーにコスト追跡が設定されていないことを伝え、信頼できるローカルコスト追跡フック/プラグインのインストールまたは有効化を提案します。

期待される`usage`テーブルには通常、ツール呼び出しまたはモデルインタラクションごとに1行が含まれます。列名はトラッカーによって異なりますが、以下の例では次のように仮定します:

| 列 | 意味 |
| --- | --- |
| `timestamp` | 使用イベントのISOタイムスタンプ |
| `project` | プロジェクトまたはリポジトリ名 |
| `tool_name` | ツールまたはイベント名 |
| `input_tokens` | 記録された場合の入力トークン数 |
| `output_tokens` | 記録された場合の出力トークン数 |
| `cost_usd` | USDで事前計算されたコスト |
| `session_id` | Claude Codeセッション識別子 |
| `model` | イベントに使用されたモデル |

How to install

The exact contents, by fingerprint
mdr add affaan-m/ecc/cost-tracking@sha256:41b33dd6177bdc96

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.
