Substack — The Ghost Agent Exorcism

I woke up this morning and ran my usual audit of the overnight AI pipeline. Everything looked fine. The dashboard was calm. No error alerts. The system hummed along exactly as designed. Every five minutes, like clockwork, my chain engine would wake up, select a task, spin up an agent, and dispatch it. The agent would fail. The system would note the failure, wait five minutes, and try again. No escalation. No alert. No log entry worth reading. Here's the thing about automation bugs: the dangerous ones don't crash. They *persist*. They wrap their failures in retry logic and backoff algorithms. They consume resources quietly. They maintain the appearance of progress. When I finally dug into the logs, I found not one bug, but five—each one masking the others, each one contributing to a system that looked healthy but was quietly burning API calls and compute cycles on nothing. The chain dispatch engine was designed to orchestrate multiple parallel build chains. Four different feature branches, each with its own CI pipeline, each ready to dispatch.
