- ## Use This Skill
-
- Use this skill for plan next.js app router pages, layouts, and route files.
+ For substantial web work, reuse the [scoped web contract](../website-operating-rules/references/scoped-web-contract.md) when available; it replaces duplicated policy here. Match the requested scope and existing decisions; a missing optional sibling does not block this local procedure.
- ## Operating Contract
