Multi-Agent Software Systems Need Contracts and Handoffs to Run for Days

Factory’s Luke Alvoeiro argues that long-running software agents will not be built by stretching chat sessions, but by organizing agents into roles with explicit contracts, handoffs and validation. In a talk on Factory’s Missions system, he presents a three-part architecture — orchestrator, workers and validators — designed to run software work for hours or days while humans supervise scope and acceptance rather than every step. The case rests on Factory’s production experience, including missions Alvoeiro says have run as long as 16 days, and on a claim that serial execution, adversarial verification and model selection by role matter more than default parallelism.
