tool-command-creator

tool-command-creator is a skill for Claude Code, Codex from eaglesakura/agent-skills. It costs 185 tokens per session (5,867 once invoked), scanned A, original, MIT.

A creator and editor for Cursor slash commands, which are reusable instruction files run by an AI coding agent. It defines their inputs, outputs, related files, assets, steps, checks, and safeguards.

In plain words
What is it for?
Use it to create or revise files such as .cursor/commands/*.md or .apm/prompts/*.prompt.md, including commands with flows and shared assets.
Why use it?
It removes the need to design the command format and supporting documentation from scratch. It helps keep commands consistent with the repository’s Cursor or APM layout.

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

tool-command-creator 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 4d 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.

Tool / Cursor Slash-Command Creator

slash-command は Agent が実行する再利用可能な手順書である。 入力・出力・関連資源・手順の分岐を本文で明示し、後続 Agent が迷わず実行できるようにする。

いつ使うか / 使わないか

  • 使う: .cursor/commands/ に配置する Cursor slash-command の作成・改訂
  • 使わない: Agent Skill(.cursor/skills/**/SKILL.md)の作成(skill-creator 等)
  • 使わない: 一度きりの会話プロンプトの下書きだけ(ファイルとして残さない場合)

出力先と命名

  • プロジェクト共有: .cursor/commands/{command-name}.md
  • APM パッケージのソース: .apm/prompts/{command-name}.prompt.md(install 後に .cursor/commands/ 等へ展開される)
  • ファイル名がコマンド名になる(例: docs.render.md/docs.render
  • このリポジトリでは {領域}.{動詞や目的} のドット区切りを推奨する(例: docs.format-plan, git.preflight
  • 本文 H1 はファイル名ではなく、内容要約のタイトル(例: 実装フロー / 要件定義)にする

共有アセット

コマンド本文に長い書式・テンプレート・複数コマンドで共有する資料を埋め込まない。 ファイル参照は ## 関連ファイル、探索ディレクトリは ## アセットディレクトリ に分ける。

リポジトリ直下のコマンド(未パッケージ)

  • 配置: .cursor/extra/{領域またはコマンド名}/...
    • 領域共有の例: .cursor/extra/docs/requirements.md
  • コマンドからの参照は相対パス(例: [requirements.md](../extra/docs/requirements.md)
  • {assets}/ を使う場合は ## アセットディレクトリ に候補ディレクトリを列挙する

APM パッケージ内のコマンド

  • ソース配置: .apm/assets/{領域またはコマンド名}/...
    • 例: .apm/assets/example.command/template.md
  • 本文・## 関連ファイル ではインストール先の 1 パスを直書きせず、{assets}/... メタ変数を使う
    • 例: {assets}/template.md
  • {assets}/ を使う場合は、本文の ## アセットディレクトリ に実ディレクトリ候補を列挙する(正本)
    • ソース相対(開発時): ../assets/example.command/
    • install 後ルート相対: apm_modules/**/agent-creator/.apm/assets/example.command/
  • 旧来の metadata.assets だけがある文書も workspace-resolve-agent-assets は読めるが、新規・改訂では本文セクションへ書く
  • 実行時の実体解決は workspace-resolve-agent-assets に従う(文書相対とワークスペースルート相対の両方を試し、ヒットを示す)

コマンド単体に閉じる短い例示だけなら本文に書いてよい。書式の正本・長いテンプレート・共有ルールはアセットへ寄せる。

必須: テンプレート準拠

出力は必ず assets/command.md に従う。 プレースホルダ({...})と HTML コメントは最終成果物から除去する。

生成コマンドの実行契約(必須)

作成・改訂する slash-command 自体が、実行時に次を守るように書く。

非対話

  • ユーザーへの確認質問・選択肢提示・追加情報の依頼を行わない
  • 不足情報を対話で補完せず、文脈・引数・既存ファイルから確定できる範囲だけを使う

不明確はエラー終了(実行時)

次のいずれかが明確にならない場合は、処理を続けずエラーとして終了する。

  • 入力(Required の欠落、解釈不能、矛盾)
  • 出力(保存先・形式・成功条件が特定できない)

手順の不明確は実行時エラーにしない。 生成コマンドの最終出力(手順・ガードレール・フローチャート)に「手順が不明確です」等の分岐を書かない。

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.
