Five subagents.
The one from the video: five test users walk through your app before anyone else sees it and tell you where they get confused, stuck or leave.
Prompt · Hack #1
Act as my launch QA lead. Spin up 5 subagents, each a different first-time user:
1. The impatient one: skims, clicks the first button, quits at the first error
2. The skeptic: reads pricing, terms and privacy before signing up
3. The mobile user: does everything on a 375px screen on slow 3G
4. The non-native English speaker: only follows what the UI literally says
5. The breaker: pastes junk into forms, hits back mid-flow, double-clicks everything
Each one opens the app in a real browser, goes from landing page to first success, and screenshots every moment they get confused, stuck or annoyed.
Merge everything into one list ranked by how many users hit it. Fix it all in one pass, then rerun the 5 users to prove it's fixed.
(Works best with a browser MCP connected: Playwright or Chrome DevTools.)Paste it into Claude Code or Codex inside your project. To let the subagents open your app for real, connect a browser MCP such as Playwright or Chrome DevTools.
