+Read the diagram in five layers:
+
+- **Inputs**: rough operational material becomes the source for a reusable skill package.
+- **Router**: `SKILL.md` stays small and decides boundary, mode, and output contract first.
+- **Method layer**: doctrine files explain whether the request should become a skill and which quality gates it deserves.
+- **Authoring flow**: the unified CLI turns creation, validation, optimization, promotion, reporting, and packaging into one path.
+- **Evidence and outputs**: the result is not only a skill package, but also eval artifacts, governance signals, portability outputs, and iteration history.
+
 ## Quick Start
 
 1. Describe the workflow, prompt set, or repeated task you want to turn into a skill.

+## Architecture
+
+Le système est volontairement organisé par couches afin qu'un nouveau venu puisse le lire de haut en bas : d'abord le routage, ensuite la méthode, puis la validation, et enfin le packaging et la gouvernance.

+```
+
+On peut lire ce schéma en cinq couches :
+
+- **Couche d'entrée** : les matériaux opérationnels bruts servent de source au futur skill package.
+- **Couche de routage** : `SKILL.md` reste léger et définit d'abord les frontières, le mode et le contrat de sortie.
+- **Couche méthode** : les documents de doctrine déterminent si la demande mérite d'être skillifiée et quels garde-fous elle doit recevoir.
+- **Couche de flux auteur** : le CLI unifié relie création, validation, optimisation, promotion, reporting et packaging.
+- **Couche preuves et sorties** : le résultat n'est pas seulement un skill package, mais aussi des evals, des signaux de gouvernance, des sorties de portabilité et un historique d'itération.

 ## Quick Start
 
 1. Décrivez le workflow, l'ensemble de prompts ou la tâche répétée que vous voulez transformer en skill.

+
+このシステムは層構造になっており、新しい利用者でも上から順に理解できます。最初に route を決め、次に method を選び、その後に検証し、最後に package と governance を扱います。

+
+この図は 5 つの層として読むとわかりやすいです。
+
+- **入力層**: 断片的な運用資料を skill 化の原材料にします。
+- **ルーター層**: `SKILL.md` は軽量のまま、境界、モード、出力契約を先に決めます。
+- **メソッド層**: method 文書が、skill 化すべきか、どの quality gate が必要かを決めます。
+- **作者フロー層**: 統一 CLI が作成、検証、最適化、昇格、レポート、パッケージ化を一つの流れにします。
+- **証拠と出力層**: 最終成果は skill package だけでなく、eval 結果、governance signal、portability 出力、iteration history も含みます。

+
+Эту схему удобнее читать как 5 слоев:
+
+- **Слой входов**: разрозненные операционные материалы становятся сырьем для будущего skill package.
+- **Слой routing**: `SKILL.md` остается легким и сначала определяет границы, режим и output contract.
+- **Слой method**: doctrinal docs определяют, стоит ли вообще skill-изировать запрос и какие quality gates ему нужны.
+- **Слой authoring flow**: единый CLI связывает создание, проверку, оптимизацию, promotion, reporting и packaging.
+- **Слой доказательств и выходов**: итогом становится не только skill package, но и eval-артефакты, governance signals, portability outputs и история итераций.

 1. Опишите workflow, набор prompts или повторяющуюся задачу, которую хотите превратить в skill.

+- **作者流层**：统一 CLI 把创建、校验、优化、晋升、报告和打包串成一条路径。
