At Nala Vet, we run a single fly.io machine as an always-on AI operations agent for our mobile veterinary clinic. It reads our CRM, reschedules appointments, sends SMS, opens PRs on GitHub, and posts a daily briefing to Telegram — all from one container. Here's exactly how we built it and what we learned.

How we use harness to put a sandboxed coding agent inside our veterinary monorepo and a Telegram-reachable claw on fly.io — without ever handing either of them our AWS credentials.
