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 | $0.00046 | $0.01879 |
| Opus 5 | $0.00023 | $0.00940 |
| Sonnet 5 | $0.00009 | $0.00376 |
| Haiku 4.5 | $0.00005 | $0.00188 |
Grade A, and why
Altitude Generalization 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
由来: Claude Code の
/simplify（Altitude 観点）に由来（inspired by）。Issue #1452 P3 で、skills/agent-skills/river-review-code/references/SIMPLIFY.mdから Altitude の詳細検出を本 registry skill へ委譲した。
Pattern declaration
Primary pattern: Reviewer Secondary patterns: Inversion Why: 共有基盤への継ぎ接ぎ（bandaid）をチェックリストで評価するが、special-case の証拠が差分に無い変更では実行しない。
Goal / 目的
- 共有基盤・共通関数に「特定の呼び出し元のためだけ」の分岐（bandaid）が積み上がるのを防ぐ。
- 同種の special-case が2つ以上ある場合に、下層機構の一般化（設定テーブル / strategy / caller ごとの宣言的マップ）を促す。
Non-goals / 扱わないこと
- correctness bug・セキュリティ欠陥は対象外（bug 系・security 系観点の責務）。
- 設計思想への一般論（「もっと抽象化すべき」等、差分に証拠のない主張）は出さない。
- リファクタ完了主張の反証は
refactor-claim-auditの責務であり、本観点では扱わない。
applyTo に scripts/** と runners/** を含める理由
applyTo の各 glob は拡張子で境界付けした midstream ソース限定（scoping ガイド「midstream (application source)」の範囲内）である。SIMPLIFY 観点は src/ だけでなく scripts/・runners/ で実行されるコードにも special-case が生じ得る（P2 実地検証では scripts/** の hygiene / 検証ロジックが対象になった）。本 skill はその applyTo 経路差を解消するため、実行コードを持つ3ルートを対象にする。tests/**・docs/**・dist/** は含めない。
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。dispatcher 経路では Gate が強制されないため、実行時に本文の Gate を必ず自己適用する。
- 差分にリポジトリ内で実行されるコード（
src//scripts//runners/配下の.ts/.tsx/.js/.jsx/.mjs/.cjs）の変更が含まれている。 - 差分に呼び出し元を特定する special-case の証拠（呼び出し元判定の条件分岐・専用フラグ・型チェックによるバイパス）が少なくとも1つ含まれている。
-
inputContextにdiffが含まれている。 - ビルド成果物・生成物（
dist/**・*.map・lockfile・自動生成 manifest）のみの差分ではない。
ゲート不成立時の出力: NO_REVIEW: altitude-generalization — 共有基盤への caller special-case の証拠が差分に検出されない
False-positive guards / 抑制条件
Gate を通過した上で、以下は指摘しない（黙る）。
- 意図的な host opt-in: 分岐が呼び出し元 ID ではなく、任意の呼び出し元が渡せる第一級の公開オプション/フラグ（例:
options.compactのような公開整形オプション）を条件にしている場合。これは bandaid ではなく正当な API 拡張である。 - special-case が差分内に1つのみで、同種の先行 special-case が差分外にも存在しない場合（単発の分岐は「正しい深さ」の可能性が高く、一般化を急がない）。証拠のある同種の special-case が2つ以上そろって初めて一般化を提案する。
- 指摘行（finding の
file:line）が差分内に無い場合。 - 意図的な非 DRY（過度な抽象化の回避）が差分・コメントから読み取れる場合。

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.

Altitude Generalization Guard is a skill published in the GitHub repository s977043/river-review (3 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 1,879 once invoked, about $0.0002 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.

review-all
Multi-agent code review for diffs (project-agnostic). Covers standards, bugs, security, DRY, smells, perf, tests, API contracts, a11y/i18n. Verifies each finding to eliminate false positives. Use for /review-all, pre-PR/pre-commit review, or auditing uncommitted/staged changes.
logic-health
Sweep a directory, module, or full codebase for logic correctness and produce a scored health dashboard with systemic patterns. Trigger when the user requests a health view — "audit the whole codebase", "health check", "health overview", "logic health overview", "audit src/", "audit auth and payments modules", "where…
logic-diff
Compare two code versions for semantic equivalence via semi-formal tracing of both versions side-by-side. Trigger when the user shares a refactor, rewrite, migration, or A/B implementation and wants to confirm behavior is unchanged — "did I break anything", "is this equivalent", "are these equivalent", "semantically…
