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

openapi-mcp markdown.instructions.md 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 2mo 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.

Markdownファイル作成・編集指針

コーディング規約

以下のルールは必ず遵守してください。 違反が見つかった場合は即座に修正が必要です。

インデントルール

  • スペースインデント使用(タブ禁止)
  • インデントは4スペース固定(2スペースは不可)

見出しルール

基本ルール
  • h1はドキュメント内で1つのみ
  • 見出しレベルは段階的に増やす(h1→h2→h3、レベルスキップ禁止)
    • 見出しレベルは一度に1段階以上増加させてはいけない
    • 正: h1 → h2 → h3 → h4
    • 誤: h1 → h3 (h2をスキップ)
    • h2の直下はh3から開始し、必要に応じてh4以降へ段階的に増やす
    • h2の直下にh4を置かない
  • 見出しの前後に空行を1行入れる
見出しレベル別の記法
  • h1: 見出し文 + 下線(===== 長さ25文字固定)
  • h2: 見出し文 + 下線(----- 長さ25文字固定)
  • h3: ### 見出し文
  • h4: #### 見出し文
  • h5: ##### 見出し文
  • h6: ###### 見出し文
見出しの表記ルール

【重要】見出しは見出し記法で記述します

  • 見出しは必ずh1〜h6の見出し記法で記述します
    • OK例: ##### 詳細項目 (適切なh5見出し)
    • NG例1: **詳細項目** (h5/h6相当の内容を太字で表現)
    • NG例2: * **小見出し**: 説明文 (リスト内で太字を見出し代わりに使用)
    • NG例3: **小見出し** (本文の太字だけで見出しに見せる)
  • 見出しの代用として太字のみの行を置きません
  • 見出しが6レベルを超える場合は構造を見直します
  • 太字による見出し代用を発見した場合の修正方法
    • 適切な見出しレベル(h3〜h6)に変換する
    • 見出しレベルは直前の見出しレベル+1を基準とする
    • 末尾のコロン(:)がある場合は削除する
    • 修正例: **見出し:** → ### 見出し (直前がh2の場合)
平文化された見出し候補の扱い
  • 太字禁止の適用時に、見出し候補を通常文へ平文化しません
  • 次の条件を満たす単独行は、太字除去ではなく見出し記法へ変換します
    • 20文字以内の短いラベル
    • 文末が句点(。)で終わらない
    • 直後に段落、リスト、表、コードブロックのいずれかが続く
  • 変換時は直前見出しレベル+1を基準にh3〜h6を選択します
  • 修正例: 実装手順 → ##### 実装手順
  • 修正例: 前提条件 → ##### 前提条件

太字使用ルール(限定的に使用)

原則: 太字は極めて限定的にのみ使用します

  • 本ルールの主目的は、LLMの注意配分を安定させることです。

  • 項目名の常時太字化は重要度の差分を失わせ、生成時のアテンションを乱しやすいため禁止します。

  • 使用可能な場合(以下のみ使用します)

    • **注意**:, **警告**:, **重要**: で始まる警告文の接頭辞のみ
    • **必須**:, **禁止**: または **<行動指示>必須**:, **<行動指示>禁止**: で始まる行動指示の接頭辞のみ
      • OK例: * **必須**: 設定を行う
      • OK例: * コミット禁止: git commitは実行しない
    • 本文中の重要語句の強調(意味解釈に必要な語句のみ)
      • 1文中は1箇所以内、1段落中は2箇所以内を推奨
      • 太字を外しても意味が変わらない場合は装飾目的とみなす
    • ルール説明文中の重要な制約事項(例: 「h1はドキュメント内で1つのみ」)
  • 太字を使用しない例

    • NG例: * **項目名**: 説明文 (装飾目的)
  • 違反例と修正例

    • NG: **実装手順** → OK: ##### 実装手順
    • NG: * **設定項目**: 詳細説明 → OK: * 設定項目: 詳細説明
    • NG: **ここに注意** → OK: **注意**: ここに注意 または 注意: ここに注意

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.
