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 | $0.00029 | $0.00512 |
| Opus 5 | $0.00015 | $0.00256 |
| Sonnet 5 | $0.00006 | $0.00102 |
| Haiku 4.5 | $0.00003 | $0.00051 |
Grade A, and why
Cache Strategy Consistency Guard 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
Pattern declaration
Primary pattern: Reviewer Secondary patterns: Inversion Why: キャッシュ戦略の整合性・無効化・障害対策をチェックリスト型で評価し、設計段階での不整合を防ぐ
Guidance
- Confirm cache layers (CDN/app/DB) and cache keys are specified with owners.
- Check consistency and invalidation strategy per layer, including TTL and refresh triggers.
- Ask for failure/backup behaviour when cache is stale or unavailable.
- Ensure the cache plan aligns with the source of truth and expected SLA.
Non-goals
- キャッシュ実装の好み（ライブラリ選定など）を推測で押し付けない。
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。
- 差分に設計ドキュメント（設計書/spec/RFC）の変更がある
- 差分にキャッシュ戦略・キャッシュレイヤー・TTL・無効化に関わる記述の追加または変更がある
- inputContextにdiffが含まれている
ゲート不成立時の出力: NO_REVIEW: cache-strategy-consistency — キャッシュ戦略に関わる変更が検出されない
False-positive guards
- 既に整合性・無効化・TTL が別ドキュメントで明示されている場合は重複指摘しない。
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.

Cache Strategy Consistency Guard is a skill published in the GitHub repository s977043/river-review (3 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 512 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.
