This skill should be used when the user asks to 'port a feature from repo A to repo B', 'migrate a repository feature faithfully', 'rewrite faithfully', 'fork-and-customize without dropping flows', 'リポジトリ間移植', '別リポジトリの機能を移植', '忠実に移植', 'A の機能を B にそのまま持ってきて', or wants to port / rewrite / re-implement an existing repository's feature set into another codebase without silently shrinking scope. It forces 1:1 enumeration, source/target architecture diagrams reviewed by the consecutive-review-loop skill, a shrink-vocabulary ban, one-outcome-per-PR, and a pre-merge local verification with screenshots.
