承認済み Spec ファイルを起点に、Isolate → Plan → Implement → Verify → Code Review → ship の 6 ステージ遷移を制御する skill。本ワークフロー (docs/workflow.md) の Spec Review 以降を担当します。 spec-review skill が verdict: pass を返した直後に自動起動します。加えて「Isolate 開始して」「spec-leader 起動」「<spec-name> の実装を始めて」等の明示フレーズでも起動します。 Phase 3 では main agent 内で単独動作可能に実装し、Phase 5 で追加する orchestrator から呼ばれる前提のインタフェース (入力: spec.md パス、出力: progress / result ファイルパス) を確定済みのため、Phase 5 で本 skill の改修は不要です。 ship ステージの実行はユーザー最終承認後に限定します。失敗時は全停止してユーザーに相談します。
