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 | $0.00108 | $0.02466 |
| Opus 5.5 | $0.00043 | $0.00986 |
| Sonnet 5.5 | $0.00022 | $0.00493 |
| Haiku 4.5 | $0.00011 | $0.00247 |
Grade A, and why
codex-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 1mo 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 — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex Review Integration Skill
OpenAI Codex CLI を使って Claude Code のコードレビュー時にセカンドオピニオンを提供するスキル。

🎯 使用場面
セットアップ
- 初回設定: Codex CLI のインストール確認と MCP 登録
- 認証設定: Codex への OAuth / API キー認証
レビュー
- セカンドオピニオン: Claude のレビュー結果に Codex の視点を追加
- コード品質チェック: 複数 AI モデルの得意分野を活用
- 設計レビュー: アーキテクチャや実装パターンの多角的検証
機能詳細
| 機能 | 詳細 |
|---|---|
| MCP セットアップ | See references/codex-mcp-setup.md |
| レビュー統合 | See references/codex-review-integration.md |
| 4並列レビュー | See references/codex-parallel-review.md |
| モード切替 | See references/codex-mode.md |
実行手順
- ユーザーのリクエストを分類
- 上記の「機能詳細」から適切な参照ファイルを読む
- その内容に従って設定またはレビューを実行
⚠️ 並列レビュー時の必須ルール
Codex モード（review.mode: codex）でのレビュー実行時:
- 呼び出すエキスパートを判定（全部ではなく必要なもののみ）:
- 設定で
enabled: false→ 除外 - CLI/バックエンド → Accessibility, SEO 除外
- ドキュメントのみ変更 → Quality, Architect, Plan Reviewer, Scope Analyst を優先（Security, Performance は除外可）
- 設定で
- 有効なエキスパートの
references/experts/*.mdから プロンプトを個別に読み込む - 有効なエキスパートのみ Bash バックグラウンドプロセスで並列実行
- 絶対に1回の呼び出しで複数観点をまとめない
✅ 正しい（並列 CLI 実行）:
# macOS: brew install coreutils
TIMEOUT=$(command -v timeout || command -v gtimeout || echo "")
$TIMEOUT 120 codex exec "$(cat /tmp/expert-security-prompt.md)" > /tmp/expert-security.txt 2>/dev/null &
$TIMEOUT 120 codex exec "$(cat /tmp/expert-perf-prompt.md)" > /tmp/expert-perf.txt 2>/dev/null &
$TIMEOUT 120 codex exec "$(cat /tmp/expert-quality-prompt.md)" > /tmp/expert-quality.txt 2>/dev/null &
$TIMEOUT 120 codex exec "$(cat /tmp/expert-a11y-prompt.md)" > /tmp/expert-a11y.txt 2>/dev/null &
wait
❌ 間違い:
codex exec "セキュリティとパフォーマンスと品質をレビューして"

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.
- 1mo ago First seen · 240 lines · 108 tokens per session scan A e355c150a809
codex-review is a skill published in the GitHub repository Chachamaru127/codex-harness (2 stars, last pushed 8mo ago), licensed MIT. It adds 108 tokens to every session and 2,466 once invoked, about $0.0004 per session on Opus 5.5. 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.
