 "repo_url": "https://github.com/arla6ka/design.how",
 "repo_slug": "arla6ka-design-how",
 "title": "Move every app screen onto a design system safely",
 "page_title": "How to move every app screen onto a design system safely with Design How",
 "summary": "Migrate all routes with parallel workers, each checked against its before screenshot.",
 "who": "A team lead with an established app who has already built or picked a design system and needs every screen moved onto it without manual restyling.",
 "problem": "Restyling dozens of screens by hand is slow, and visual regressions are easy to miss.",
 "outcome": "An audit of what needs to change, then a migration where each screen is compared with its before screenshot on a new run branch.",
 "steps": [
  "Install the skills with `npx skills@latest add arla6ka/design.how`.",
  "Ask your agent to run migrate-design-system in audit mode first, so it writes only its own notes under `.design-system/` and commits nothing.",
  "Read the audit notes and confirm the mapping of hex codes and pixel values to tokens made by token-mapping.",
  "Run the full migration, then review each screen against its before screenshot on the run branch.",
  "Merge the run branch yourself once you accept the results."
 ],
 "agent_prompt": "Using migrate-design-system from the arla6ka/design.how skills in this repo, run audit mode on <target app path> and write the results under .design-system/. Expected output: a list of screens and values to change. Verify that no commits were made in audit mode.",
 "agents": [
  "any"
 ],
 "difficulty": "Advanced",
 "time": "2 hours",
 "basis": "readme",
 "caveat": "Browser-driven checks need Playwright and a Chromium, so the migration will not run its screenshot comparisons without them.",
 "category": "Software and DevOps",
 "tags": [
  "Software and DevOps"
 ],
 "lang": "typescript",
 "requirements": [
  "A coding agent that reads skills, such as Claude Code",
  "Node.js, since the install and scripts run through npx and node",
  "Your app in a git repository, since the skills commit to a run branch",
  "Playwright and a Chromium browser for the scripts that drive a browser"
