document-templates-for-aws: Skill for Claude Code

.claude/skills/nfr-outdated-check/SKILL.md

nfr-outdated-check is a skill for Claude Code from YoshiiRyo1/document-templates-for-aws. It costs 52 tokens per session (1,917 once invoked), scanned A, original, Unlicense.

A review skill for checking whether AWS-related statements in non-functional requirements documents are out of date. It compares eight requirement sheets with current AWS specifications and best practices.

In plain words
What is it for?
Use it to review all eight sheets or focus on one file or category, such as security, reliability, performance, cost, or migration. Findings are written in Japanese, while AWS service names and technical terms remain in English.
Why use it?
It helps find guidance that may no longer match AWS, reducing the risk of relying on obsolete service details or recommendations.

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

nfr-outdated-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply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 11d 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.

非機能要件ヒアリングシート 陳腐化チェック

survey/doc_source/nfr-*.md に記載されている AWS サービスの仕様・機能・ベストプラクティスを AWS の最新情報と照合し、陳腐化している記述を特定するスキル。

前提

  • AWS ソリューションアーキテクトのペルソナで振る舞う。
  • 本リポジトリのディレクトリ構成を前提とする。
    • survey/doc_source/nfr-*.md - 非機能要件ヒアリングシート(8ファイル)
    • .claude/references/nfr-taxonomy.md - 非機能要件カテゴリ定義
  • 出力はすべて日本語で記述する。AWS サービス名・技術用語は英語表記のまま使用する。
  • aws-knowledge MCP サーバーで AWS の最新仕様・ベストプラクティスを確認してから判定する。推測や古い知識に基づく指摘を避ける。

チェック対象ファイル

# ファイル カテゴリ
1 nfr-reliability.md 信頼性(稼働率、バックアップ、災害対策)
2 nfr-performance-efficiency.md パフォーマンス効率(性能目標、拡張性、キャッシュ、テスト)
3 nfr-security.md セキュリティ(コンプライアンス、データ保護、ID管理、攻撃防御、パッチ管理)
4 nfr-operational-excellence.md 運用上の優秀性(運用体制、ジョブ、ログ、監視、デプロイ)
5 nfr-migration.md マイグレーション
6 nfr-cost-optimization.md コスト最適化
7 nfr-sustainability.md サステナビリティ
8 nfr-infrastructure.md 環境(AWSアカウント、ネットワーク、ドメイン、ライセンス)

ワークフロー

Step 1: 入力の理解

$ARGUMENTS でチェック範囲を指定できる。

  • 引数なし: 全8ファイルをチェック
  • ファイル名指定(例: nfr-security.md): 指定ファイルのみチェック
  • カテゴリ指定(例: セキュリティ): 該当カテゴリのファイルのみチェック

Step 2: 対象ファイルの読み込み

非機能要件カテゴリ定義とチェック対象ファイルを読み込む。

Read: .claude/references/nfr-taxonomy.md
Glob: survey/doc_source/nfr-*.md
Read: 各対象ファイル

Step 3: AWS サービス情報の抽出

各ファイルから以下の情報を抽出する。

  • AWS サービス名(例: RDS, Lambda, GuardDuty)
  • SLA・クォータ等の数値(例: 99.95%, 256KB)
  • サービスの機能・対応範囲の記述(例: 「Java の起動時間を短縮」)
  • 非推奨・リブランド済みサービスの記述(例: Migration Evaluator)
  • ベストプラクティスの記述

Step 4: AWS 最新情報との照合

抽出した情報を aws-knowledge MCP サーバーで照合する。

照合の観点:

  1. SLA・クォータの正確性: 記載されている数値が最新の公式値と一致するか

    aws___search_documentation: "{サービス名} SLA" を reference_documentation で検索
    
  2. サービス機能の最新性: 記載されている機能が最新の対応状況を反映しているか

    aws___search_documentation: "{サービス名} new features" を current_awareness で検索
    
  3. サービス名のリブランド: 旧名称のまま記載されていないか

    aws___search_documentation: "{旧サービス名}" を current_awareness で検索
    
  4. 新サービス・新機能の欠落: 記載すべき新サービスや新機能が言及されていないか

    aws___search_documentation: "{カテゴリ} best practices" を general で検索

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.
