I Shipped a Complete AI Mobile App Using Claude Code Subagents and Parallel Worktrees

The first thing the QA agent found was a P0 bug I'd have shipped to users. The natal chart was computing before authentication. The 401 came back silently. The reveal screen showed a mock chart instead of the real one, no error, no indication anything was wrong. TypeScript didn't catch it. Unit tests didn't catch it. A QA subagent actually rendering the app caught it in about 90 seconds. That's the case for agentic development in one bug. This is the story of building Origo, an AI astrology and tarot companion app, under Raedus Labs. The AI companion is named Vega.
