Matt Van Horn
Author of "WTF Is a Loop?," framing agent loops as cron plus model decisions, feedback, budget caps, and reusable skills.
Matt Van Horn is the author of the X Article "WTF Is a Loop? Peter Steinberger vs. Boris Cherny," which explains the 2026 AI-coding discourse around Agent Loops. In the article, he frames loops as a shift from prompting agents manually toward writing durable systems that prompt, evaluate, schedule, and supervise agents.1
His synthesis is skeptical of both pure hype and pure dismissal: loops reuse old infrastructure such as cron, but add model-driven decisions, feedback, budgets, and orchestration. He argues that the durable unit inside a useful loop is a reusable skill, connecting his view to Skillification and Harness Engineering.1
