architecture-decisions

Value: Communication -- architecture decisions recorded before implementation ensure every contributor (human or agent) understands why the system is shaped the way it is. Decisions made in silence are decisions lost.

Teaches the agent to record architecture decisions before implementing them, maintain a living architecture document, and facilitate structured decision-making. Prevents the common failure mode where architecture emerges accidentally and rationale is lost.

Never implement a structural change without first recording the decision. An architecture decision is any choice that affects system structure, technology stack, domain boundaries, integration patterns, or cross-cutting concerns.

アーキテクチャの決定記録と生きているアーキテクチャのドキュメント。テクノロジーの選択、システム境界の定義、アーキテクチャ上の決定の記録、または ARCHITECTURE.md の作成/更新を行うときにアクティブ化します。 ADR 形式、意思決定ガバナンス、設計促進、アーキテクチャ レビューをカバーします。 ソース: jwilger/agent-skills。
