Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00017 | $0.01996 |
| Opus 5 | $0.00009 | $0.00998 |
| Sonnet 5 | $0.00003 | $0.00399 |
| Haiku 4.5 | $0.00002 | $0.00200 |
Grade A, and why
create-skill 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.
This is a copy
100% identical to create-skill — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

/create-skill - スキル作成コマンド
このコマンドは、skill-creatorスキルを使って新しいスキルを作成し、reviewing-skillsスキルでレビュー・自動修正を行います。
スコープ
重要: スキルはプロジェクトスコープ(.claude/skills/)に作成します。グローバルスコープ(~/.claude/skills/)には作成しません。
skills/が存在しても.claude/skills/に作成します。
出力先: {プロジェクトルート}/.claude/skills/{スキル名}/
使い方
引数付き起動
/create-skill pdf-converter PDFファイルを画像に変換するスキル
引数なし起動(対話的)
/create-skill
[1/3] スキル情報の取得
引数の解析
引数からスキル情報を取得します:
$1: スキル名$2以降: スキルの説明
スキル名: $1
スキルの説明: $ARGUMENTS から $1 を除いた部分
$1が空の場合、AskUserQuestionツールを使用して以下を質問してください:
AskUserQuestion({
questions: [
{
question: "作成するスキルの名前を入力してください。\n\n例:\n- pdf-converter\n- code-review\n- data-analyzer",
header: "スキル名",
options: [
{
label: "名前を入力",
description: "スキル名を直接入力"
}
],
multiSelect: false
}
]
})
スキル名取得後、説明が空の場合も質問してください:
AskUserQuestion({
questions: [
{
question: "スキルの説明を入力してください。何を行うスキルですか?\n\n例:\n- PDFファイルを画像に変換し、OCR処理を行う\n- コードレビューを自動化し、改善点を提案する\n- データを分析してレポートを生成する",
header: "スキル説明",
options: [
{
label: "説明を入力",
description: "スキルの説明を直接入力"
}
],
multiSelect: false
}
]
})
[2/3] スキルの作成
TodoWriteでタスク管理
TodoWriteツールを使用してタスクを作成:
TodoWrite({
todos: [
{
content: "skill-creatorでスキルを作成",
activeForm: "スキルを作成している",
status: "in_progress"
},
{
content: "reviewing-skillsでスキルをレビュー",
activeForm: "スキルをレビューしている",
status: "pending"
},
{
content: "レビュー結果に基づいて自動修正",
activeForm: "スキルを自動修正している",
status: "pending"
}
]
})
skill-creatorの実行
Skillツールを使用してskill-creatorスキルを実行します:
Skill({
skill: "example-skills:skill-creator",
args: "[スキル名] [スキルの説明]"
})
重要:
- skill-creatorが対話的に質問してくる場合は、ユーザーから取得した情報を元に回答してください
init_skill.pyの--pathオプションにはプロジェクトスコープを指定すること:# 正しい(プロジェクトスコープ) init_skill.py [スキル名] --path {プロジェクトルート}/.claude/skills # 間違い(グローバルスコープ) init_skill.py [スキル名] --path ~/.claude/skills
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.

create-skill is a command published in the GitHub repository j5ik2o/event-store-adapter-js (24 stars, last pushed today), licensed Apache-2.0. It adds 17 tokens to every session and 1,996 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to create-skill, differing in 0 lines, and is treated as a copy.
