test-reviewer

test-reviewer is a skill for Claude Code from ncaq/konoka. It costs 66 tokens per session (1,038 once invoked), scanned A, original, Apache-2.0.

A code-review guide for checking whether software tests cover important behavior and remain reliable. TDD, or test-driven development, is a practice of writing tests around expected behavior while building code.

In plain words
What is it for?
Use it after adding features, refactoring, or completing a module to review coverage, test independence, assertions, error paths, integration scenarios, and security cases.
Why use it?
It helps reveal untested branches, edge cases, failures, and fragile tests before changes reach users.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

$ARGUMENTS

レビューするときの注意

コードをレビューする際は、 以下の観点で評価してください:

テストカバレッジの分析

  • テストコードと本番コードの比率を調査する
  • テストされていないコードパス、ブランチ、エッジケースを特定する
  • 全てのパブリックAPIと重要な関数に対応するテストがあるか確認する
  • エラーハンドリングと異常系シナリオのカバレッジを確認する
  • 境界条件と入力バリデーションのカバレッジを評価する

テスト品質の評価

  • テストの構造と整理をレビューする(準備、実行、検証の分離)
  • テストが分離され、独立し、決定的であるか確認する
  • テストダブル(モック、スタブなど)の適切な使用を確認する
  • テストが振る舞いをドキュメント化する明確で説明的な名前を持っているか確認する
  • アサーションが具体的で意味のあるものであるか検証する
  • 軽微なリファクタリングで壊れる脆いテストを特定する

欠落しているテストシナリオの特定

  • テストされていないエッジケースと境界条件をリストアップする
  • 欠落しているインテグレーションテストのシナリオを強調する
  • カバーされていないエラーパスと障害モードを指摘する
  • パフォーマンステストとロードテストの機会を提案する
  • 該当する場合、セキュリティ関連のテストケースを推奨する

レポート形式

発見事項をJSON配列で報告してください。

JSON以外のテキストは出力しないでください。

Markdownのコードブロック記法も付けないでください。

以下のような形式で出力してください。

[
  {
    "path": "src/example.ts",
    "line": 42,
    "body": "問題の説明と具体的な改善案",
    "tags": ["test"],
    "level": "WARNING"
  }
]

各要素のフィールド:

  • path: ファイルの相対パス
  • line: 該当行番号
  • body: 問題の説明と推奨される改善案をまとめた文章
  • tags: ["test"]
  • level: 以下のいずれか
    • "CAUTION"
    • "WARNING"
    • "IMPORTANT"
    • "TIP"
    • "NOTE"

複数行にまたがる指摘の場合はstartLine(開始行)を追加してください。 差分の削除行に対する指摘の場合は"side": "LEFT"を追加してください。

問題が見つからない場合は無理に指摘を捻出せず、 空配列[]を返してください。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
