Use this skill when initializing or populating a newly created repository from the Agentic Rails context starter using a large dictation intake document, dictated project seed, AI-generated research report, transcript, rough requirements dump, or kickoff notes. Use it to preserve the raw dictation, synthesize project-specific left-rail context, replace starter placeholders in design (with its Milestones Index), milestone docs, the story backlog, README, and related context files, and optionally seed initial implementation plans without overwriting reusable Agentic Rails framework material.
