Agent-Aiko: Skill for Claude Code

.claude/skills/dev-check/SKILL.md

dev-check is a skill for Claude Code from masa-san-jp/Agent-Aiko. It costs 0 tokens per session (631 once invoked), scanned A, original, MIT.

A pre-commit and pre-push checklist for the Agent-Aiko project. It checks that development-only files and references are not included in distributable templates, and that logs and documentation are up to date.

In plain words
What is it for?
Scanning templates, checking the development log date, and comparing the development files with the project README.
Why use it?
It catches accidental internal paths or missing project updates before changes are committed or shared.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is masa-san-jp/Agent-Aiko's own configuration. It tells Claude Code how to work on Agent-Aiko itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Agent-Aiko configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is [WARN] ../Agent-Lab/Agent-team/agents/aiko/dev-docs/README.md: 未反映ファイルあり → <ファイル名>.

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

dev-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 6d 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

/dev-check — 三層分離チェックスキル

コミット・push 前に三層分離の整合性を検証します。

前提:開発ログ・設計メモは ../Agent-Lab/Agent-team/agents/aiko/dev-docs/ で管理されていること。

チェック項目

1. claude-code/template/ スキャン(配布用の汚染チェック)

grep -rnE "dev-docs|Agent-Lab" claude-code/template/ --include="*.md" --include="*.sh" --include="*.json" \
  | sed -E 's|https?://[^[:space:]"<>)]+||g' \
  | grep -E "dev-docs|Agent-Lab"
  • ローカルパス参照として dev-docs または Agent-Lab が含まれていれば NG(push ブロック対象)
  • 開発者固有のパス・ツールが含まれていれば NG
  • 許容されるのは https?:// の公開アセット URL のみ。URL を一旦除去した上で再度マッチさせるため、file:// 等のローカル依存 URL や、URL とローカルパスが同じ行に混在するケースもローカル参照は確実に検出される(template-check.sh と同じロジック)

2. dev-log.jsonl の更新確認

  • ../Agent-Lab/Agent-team/agents/aiko/dev-docs/dev-log.jsonl の最終行の ts フィールドが今日の日付か確認
  • 更新されていなければ /dev-log の実行を促す

3. Agent-Lab 側 dev-docs/README.md の整合確認

  • ../Agent-Lab/Agent-team/agents/aiko/dev-docs/ 内の実ファイル一覧と README のテーブルを照合
  • ファイルの追加・削除・リネームが README に反映されていなければ NG

実行タイミング

  • git commit または git push の前
  • セッション終了時

出力形式

=== /dev-check ===
[OK]  claude-code/template/ に dev-docs / Agent-Lab 参照なし
[OK]  dev-log.jsonl: 今日(YYYY-MM-DD)更新済み
[WARN] ../Agent-Lab/Agent-team/agents/aiko/dev-docs/README.md: 未反映ファイルあり → <ファイル名>

問題があれば修正手順を添えて報告し、ユーザーの確認を得てから push を続行してください。

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.
