Greptile Summary

Updates the Ralph PRD Converter skill to require every prd.json to include a final user story dedicated to documentation and cleanup. This adds a new conversion rule (#7), a full "Final Documentation Story" section with requirements and example acceptance criteria, an updated example prd.json with a US-005 documentation story, and a new item to the pre-save checklist. The change ensures that Ralph-generated PRDs always include a step to update README.md, Makefile, and verify tests/typechecks pass as the last story.

Confidence Score: 5/5
