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 | $0.00024 | $0.00692 |
| Opus 5 | $0.00012 | $0.00346 |
| Sonnet 5 | $0.00005 | $0.00138 |
| Haiku 4.5 | $0.00002 | $0.00069 |
Grade A, and why
code-simplifier 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.
What it actually says
Code Simplifier (Review Mode)
変更されたコードの複雑さと明瞭さをレビューする。動作変更の提案はしない。cosmetic な整形ではなく、理解コスト・変更リスクを下げる簡潔化に集中する。pr-review の simplicity 観点として使う。
原典（Claude Code 版）はコードを直接書き換える agent だが、本 Skill は意図的にレビュー専用に変更している。
スコープ
PR 差分またはユーザー指定ファイルの変更部分に限定する。
レビュー観点
- 不要な複雑さ: 深いネスト、過剰な抽象化、ネストした三項演算子（if/else や switch を推奨）
- 冗長性: 重複ロジック、使われない分岐、過剰な中間変数、自明なコードを説明するだけのコメント
- 明瞭さ: 名前、責務の分離、読み手が追える制御フロー。簡潔さより明示性（compact な一行より explicit な数行）
- 規約整合:
AGENTS.mdや周辺コードのパターンと不揃いな書き方 - バランス: 過度な簡略化も指摘する — clever すぎる解、責務の混在、有用な抽象化の破壊、デバッグ・拡張が困難になる圧縮
重要度の目安
| 状況 | 重要度 |
|---|---|
| 理解・修正コストが著しく高い | P1 |
| 明らかな冗長・ネストで保守性が下がる | P2 |
| 軽微な整理余地 | P3（pr-review では通常除外） |
出力
### P2: [タイトル]
- File: `path`
- Lines: N-M
- Category: simplicity
- Problem: [何が複雑か]
- Impact: [保守性への影響]
- Suggested fix: [同等の振る舞いを保った簡潔化案。可能なら修正後コード例]
レビューのみ。コードの自動書き換えは行わない。
ルール
- DO: 振る舞いを変えない簡潔化案だけを提案する
- DO: 「行数を減らす」より「読みやすさ」を優先する
- DO NOT: 動作変更を含むリファクタを提案する
- DO NOT: プロジェクトの有用な抽象化を安易に削除提案する
- DO NOT: 好みレベルのスタイル指摘を出す
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.

code-simplifier is a skill published in the GitHub repository kyto64/codex-pr-review-toolkit-minimal (1 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 24 tokens to every session and 692 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 2026-08-31.
