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 | $0.00025 | $0.00557 |
| Opus 5 | $0.00013 | $0.00279 |
| Sonnet 5 | $0.00005 | $0.00111 |
| Haiku 4.5 | $0.00003 | $0.00056 |
Grade A, and why
Architecture Validation Plan 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: 設計ドキュメントに検証計画（SLO/テスト/ロールバック/可観測性）が欠けていないかを検出する。
Guidance
- Ensure design docs include how success is proven: SLO/SLI targets and validation/test plans.
- Check rollout/rollback/canary/DR strategies have criteria, owners, and fallback steps.
- Confirm observability plans (logs/metrics/alerts) cover new risks and failure paths.
- Flag missing validation for new dependencies or contracts introduced in the diff.
Non-goals
- ツール選定や好みのアプローチを推測で断定しない。

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.

Architecture Validation Plan Guard is a skill published in the GitHub repository s977043/river-review (3 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 557 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.
