+## Attribution
+
+This skill was inspired by [code-to-prd](https://github.com/lihanglogan/code-to-prd) by [@lihanglogan](https://github.com/lihanglogan), who proposed the original concept and methodology in [PR #368](https://github.com/alirezarezvani/claude-skills/pull/368). The core three-phase workflow (global scan → page-by-page analysis → structured document generation) originated from that work. This version was rebuilt from scratch in English with added tooling (analysis scripts, scaffolder, framework reference, quality checklist).
