The Engineering of Intent, Chapter 29: Vibe Coding in the Backend

Chapter 29 of The Engineering of Intent blog series. Backends are unusually well suited to agentic development — but each subdomain has characteristic failure modes. A teaser on API design, migrations, job idempotency, caching, auth, and the billing-service rewrite that shipped in four months via extraction rather than vibes.
