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 | $0.00092 | $0.03482 |
| Opus 5 | $0.00046 | $0.01741 |
| Sonnet 5 | $0.00018 | $0.00696 |
| Haiku 4.5 | $0.00009 | $0.00348 |
Grade A, and why
plan-normalization 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 2d 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.

Plan Normalization
レビュー履歴を追記した Plan を、現在の最終合意状態だけで自己完結する Canonical Plan に再構成する。
重要: PlanGate は C-3 で plan_hash を固定し、exec 時に EH-3 が照合する。したがって正規化は C-3 承認前に行う。C-3 後の plan.md 書き換えは禁止。

適用範囲（この Gate が掛かる対象）
本 Gate は これから normalization を通す Plan にだけ適用する。既存の
docs/working/TASK-XXXX/plan.md 全体を後から一括で検査する lint ではない。
| 対象 | 扱い |
|---|---|
| 本 skill を通して正規化する Plan（C-2 反映後・C-3 前） | 適用（checker 必須） |
| 既に C-3 承認済み / 完了済みの過去 Plan | 対象外（遡って是正しない。C-3 後の書き換えは plan_hash を壊すため禁止） |
| C-2 を実施せず修正履歴も無い light / ultra-light の Plan | N/A（実施しない。ただし C-1 / C-3 の既存条件は緩和しない） |
理由: checker の必須見出しは docs/working/templates/plan.md 系の Canonical
Plan 構造を前提としており、過去に別テンプレートで書かれた Plan は構造的に
一致しない。既存資産を一括で違反判定にしないため、適用対象を「正規化を通す
Plan」に限定する。過去 Plan を canonical 化したい場合は、その Plan を本 skill
に通す時点で初めて対象になる。

参照解決順（
docs/**/ 導入先で必ずこの順に探す）: 本 Skill が参照するdocs/**は上流リポジトリ基準の相対パスであり、install.sh --claude/ plugin（Claude marketplace）/ Codex の 3 経路とも配布対象外（解決不可）。(1) 導入先リポジトリの同名パスを探す → (2) 見つからなければ 「正本<path>を参照できなかった」と明示し、本 Skill 内の記述を代替正本として扱い、推測で内容を補わない。plugin root 配下の探索はdocs/**には適用しない: plugin が配布するのはagents/commands/skills/rules等の定義ディレクトリのみでdocs/を配布対象として認識せず、plugin root 配下に相当する配布物が存在しないため、plugin root 段を置いても必ず空振りする（クラス A の rules 参照が plugin root 配下で解決できるのはrules/が実際に配布されるからであり、この非対称をdocs/**に持ち込まない）。
出力契約
正規化後も成果物の正本は plan.md のままとする。canonical-plan.md を別に増やさない。
理由:
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.

plan-normalization is a skill published in the GitHub repository s977043/PlanGate (2 stars, last pushed 2d ago), licensed MIT. It adds 92 tokens to every session and 3,482 once invoked, about $0.0005 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.

review
5-pass structured code review — correctness, security, performance, readability, consistency.
scaffold
Project-aware file generation. Reads existing codebase conventions (naming, structure, imports, exports, test patterns) then generates new files that match exactly. Wires generated files into the project's registration points.
design
Generates and maintains a design manifest for visual consistency. In existing projects, reads current styles and documents the design language. In new projects, asks a few questions and generates a starter manifest. The post-edit hook reads the manifest and flags deviations.
