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.

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 | $0.00274 | $0.00274 |
| Opus 5 | $0.00137 | $0.00137 |
| Sonnet 5 | $0.00055 | $0.00055 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
security 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.
What it actually says
Security Rules
秘匿情報の保護
- 秘匿値（token, API key）を絶対に出力・ログに含めない
.envファイルに実際のトークンをコミットしないLocalStorageやCacheに秘匿値を保存しない
入力の検証
- すべてのユーザー入力をバリデーションする（zod を推奨）
- 外部 API へのリクエストにタイムアウトと Abort Controller を設定
- Rate limit（429）や 5xx エラーには指数バックオフでリトライ
API クライアントのベストプラクティス
- タイムアウトは最大 30 秒
- AbortSignal でキャンセル可能にする
- リトライは最大 3〜5 回、指数バックオフで待機
- エラーレスポンスは詳細をユーザーに見せすぎない
依存関係の管理
- 定期的に依存パッケージを更新
- 脆弱性スキャンを実行
- 最小権限の原則に従う
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.

security is a cursor rule published in the GitHub repository KazunariNakayama/raycast-extensions (2 stars, last pushed 9mo ago), licensed MIT. It adds 274 tokens to every session, about $0.0014 per session on Opus 5. 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.
