 "title": "Improve an existing app screen against category leaders",
 "page_title": "How to improve an existing app screen against category leaders with Appllama Skills",
 "summary": "Give an agent a screenshot, code, or Copy Screen ID and have it rebuild the screen to a higher bar.",
 "who": "An app developer whose screen feels off or dated and who wants a concrete redesign grounded in what top apps do.",
 "problem": "It is hard to tell which parts of a screen are weak or what better screens in the same category actually do.",
 "outcome": "A revised screen in code, plus a short explanation of which patterns from the category were applied and why.",
 "steps": [
  "Run `npx skills@latest add appllama/appllama-skills` from your project root.",
  "Connect the Appllama MCP at `https://mcp.appllama.io/mcp` and approve it with your Appllama account.",
  "Collect the screen as a screenshot, its code, or a \"Copy Screen ID\" reference from appllama.io.",
  "Ask your agent to use the appllama-usage improve-a-screen playbook and the appllama-app-design-skill build bar on that screen.",
  "Compare the before and after simulator recordings and keep only the changes that hold up next to the category screens."
 ],
 "agent_prompt": "Using the appllama/appllama-skills repo, take the screen at <screenshot, code path, or Copy Screen ID> and improve it against the top-grossing apps in its category through the Appllama MCP. Output the revised screen code and a list of changed patterns, and verify the result in the simulator before reporting it.",

 "difficulty": "Intermediate",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "The README says the design skill is sharper with the MCP connected, so the research step adds value only when the MCP is set up and credited.",

  "Software and DevOps"
 ],
 "lang": "",
 "requirements": [
  "An MCP-capable agent such as Claude Code, Cursor, or Codex",
  "An Appllama account with Pro, since MCP access is part of Pro",
  "An Expo / React Native project and a simulator for the build loop"
