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 5.1 | $0.00000 | $0.00631 |
| Opus 5.5 | $0.00000 | $0.00252 |
| Sonnet 5.5 | $0.00000 | $0.00126 |
| Haiku 4.5 | $0.00000 | $0.00063 |
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 1mo 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。
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.

dev-check is a skill published in the GitHub repository masa-san-jp/Agent-Aiko (3 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 631 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

publish-npm-version
Cuts the next release of Prisma 8: bumps the root package.json version (on the v8 RC line: 8.0.0-rc.N → rc.N+1), propagates it to every workspace package, and opens a PR titled "chore(release): bump to ". When the maintainer merges the PR, the Publish to npm workflow runs automatically and ships the new version to npm…
