The app manages 6,000-person conference logistics across 10 parallel tracks, featuring an agentic CMS with human-in-the-loop approval, multi-surface agent access (web app, Slack, email), audit logging with rollback, and a Cloudflare/D1 backend deployed via GitHub Actions. The entire codebase was written by AI (primarily Gemini via Cursor) with Swyx only testing and providing feedback. Key insights shared: prefer mini models for speed and cost, avoid unbounded agent autonomy, keep code modular for parallel agent workflows, and let the OS handle voice rather than individual apps. ## Full article daily.dev links to this article rather than hosting it.
