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

design-review 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 5d 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.

What it actually says

デザインレビュー

HTMLファイルを melta UI デザインシステム(design/contracts/rules.json を正とする)に照らしてレビューし、違反を検出・分類・修正提案する。

手順

Step 1: 対象のHTMLファイルを特定する

  • 引数でファイルパスが指定されている場合 → そのファイルを読み込む
  • 引数がない場合 → examples/ 配下のHTMLファイルを一覧表示し、ユーザーに選択してもらう
  • 対象がHTMLファイルでない場合 → 「HTMLファイルを指定してください」と返す

対象ファイルを全文読み込む。

Step 2: DSリファレンスを読む

  • design/contracts/rules.jsonSSOT。ID / severity / detector / pattern / alternative / automationStatus を持つ全禁止ルール)

補助(任意):

  • foundations/prohibited.md — 人間向けの prose 版。SSOT ではなく、pattern を持つルールの一部しか載っていないので、これだけで判定しない

Step 3: チェックリストに沿って違反を検出する

references/checklist.md観点。HTML のどこをどう見るかの手順)を読み込み、各項目の [ID] を Step 2 で読んだ rules.json から引く。severity / detector / alternative の値は rules.json が正。

references/rules-index.md全文を読まなくてよい。checklist に無いカテゴリを横断して探すときの索引(カテゴリ別の表 + human-only 節 + 機械検出済み節)として、必要な箇所だけ参照する。

checklist.md のカテゴリ順にHTMLを走査する:

  1. カラー
  2. スペーシング・レイアウト
  3. タイポグラフィ
  4. モーション
  5. ボーダー
  6. フォーム(fieldset/legend カード干渉、日付セレクト幅を含む)
  7. アクセシビリティ

checklist.md に載っていないカテゴリ(modal / stepper / tag / list / table / skeleton / datepicker / baseline / ai-pattern / philosophy / button / divider)の違反を見つけた場合は、rules-index.md から ID を引いて報告する。

報告する違反には必ずルール ID を添える。 rules.json に存在しない ID を書かない(tests/skill-rule-refs.spec.ts が実在性を検査している)。対応するルールが無い指摘は違反ではなく「評価不可(ルール無し)」として扱う。

Step 4: 偽陽性を排除し、重大度を判定する

references/severity-rules.md を読み込み、以下を実行:

  1. 「推奨」と「必須」を区別 — 推奨事項は違反として報告しない
  2. 文脈判定で偽陽性を排除 — label/aria-current/text-xs の文脈確認
  3. 重大度を割り当て — Critical / High / Medium / Low の4段階。固定ルールに従い、表に無いものは rules.json の severity から変換する

Step 5: レポートを出力する

references/report-template.md を読み込み、テンプレートに沿ってレポートを出力する。

レポートには ## 評価不可 節を必ず含める(human-only / 静的に観測できない / 対応ルール無しの3種)。評価不可の項目は違反件数に含めない。

出力前に サマリー整合チェック を実施: 本文中の各重大度の件数と冒頭サマリーの件数が一致することを確認する。

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
