Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions Claude Code; installed under .agents/ (shared by several agents).

This is j5ik2o/event-store-adapter-js's own configuration. It tells Claude Code and Codex how to work on event-store-adapter-js itself, so it is not a mod to install elsewhere.

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

reviewing-skills 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.

Origin

This is a copy

100% identical to reviewing-skills — 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.

  2. best-practices.md でチェックリストを確認
  3. YAMLフロントマター(name, description)を解析
  4. ボディコンテンツの構造を分析

ステップ3: ベストプラクティスとの照合

各カテゴリを評価:

フロントマターチェック

  • name: 長さ、形式、命名規則
  • description: 完全性、具体性、トリガー

ボディチェック

  • 行数(目標: 500行以下)
  • 構造の明確さ
  • Progressive Disclosureの使用
  • ワークフロー設計の品質

コンテンツチェック

  • 用語の一貫性
  • 例の品質
  • テンプレートの適切さ

アンチパターン検出

  • デフォルトなしの複数選択肢

レポート提示後:

  1. ユーザーに修正を希望するか確認
  2. Critical問題を優先的に修正
  3. 段階的に修正を適用
  4. 各修正後に再検証

重大度分類

Critical

スキルの正常な機能を妨げる問題:

  • descriptionが空または不足
  • ボディが500行を大幅に超過
  • スクリプトのセキュリティ脆弱性
  • スクリプトのエラー処理不足

Warning

スキルの効果を低下させる問題:

  • Progressive Disclosureが適用されていない
  • 例が不十分
  • 用語が一貫していない
  • ワークフローが不明確

Info

改善の機会:

  • より簡潔にできる
  • 構造の最適化
  • 追加の例があると良い

Files

What ships with it

1 file 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.
