27 AI agents rebuild a paid app in 3 hours and catch a dangerous Windows file-deletion bug

A developer rebuilt a paid app in 3 hours 12 minutes using 27 specialized AI agents, and the security agent caught a dangerous Windows file-deletion bug involving the shortened "DOCUME1" path before release.
The system splits work across role-specific agents: Scout analyzes the target app, Risk hunts security vulnerabilities, Dev builds separate modules, LP creates the landing page, Sim tests on real hardware, and Reviewer & Fixer handles errors. Humans intervene at only three checkpoints: defining the technical contract, reviewing the security report, and approving the final release.
Key takeaway: more agents don't automatically mean better results — strict validation, security checks, and human approval are what make multi-agent systems reliable.
