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 5.1 | $0.00021 | $0.00484 |
| Opus 5 | $0.00010 | $0.00242 |
| Sonnet 5 | $0.00004 | $0.00097 |
| Haiku 4.5 | $0.00002 | $0.00048 |
Grade A, and why
Security & Privacy Design Review 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 7d 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
Pattern declaration
Primary pattern: Reviewer Secondary patterns: Inversion Why: プライバシー設計レビューはチェックリスト型評価が主だが、データ関連の設計変更がない差分では実行を止めるゲートが必要
Guidance
- Check retention/deletion policies, including backups, residency, and cross-border handling.
- Ensure privacy rights flows (erasure/export) and audit logging are defined with access controls.
- Verify encryption and access control strategy for data at rest/in transit.
- Call out missing threat/abuse considerations for sensitive data paths.
Non-goals
- 実装詳細や規約の推測だけで断定しない。
Pre-execution Gate / 実行前ゲート
このスキルは以下の条件がすべて満たされない限りNO_REVIEWを返す。
- 差分にデータ保持・削除・暗号化・プライバシーに関連する設計ドキュメント変更が含まれている
- 差分が非データ領域のみの変更ではない
- inputContextにfullFileが含まれている
ゲート不成立時の出力: NO_REVIEW: security-privacy-design — プライバシー・データ設計に関連する変更が検出されない
False-positive guards
- 別文書で保持/削除/暗号化ポリシーがすでに明示されている場合は黙る。
What ships with it
8 files 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.
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 & Privacy Design Review is a skill published in the GitHub repository s977043/river-review (3 stars, last pushed today), licensed MIT. It adds 21 tokens to every session and 484 once invoked, about $0.0001 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 2026-09-03.
