The Multi-Agent Architecture That Actually Ships — Luke Alvoeiro, Factory
May 6, 2026 · 18:31
Luke Alvoeiro from Factory presents Missions, a multi-agent architecture that combines delegation, creator-verifier, broadcast, and negotiation into a three-role system of orchestrator, workers, and validators. The central claim is that human attention, not AI intelligence, is now the bottleneck in software engineering. Missions uses validation contracts written before any code to define correctness independently, structured handoffs to maintain context across 16-day runs, and serial execution with targeted internal parallelization to reduce errors. Strategic model selection per role—planning, implementation, validation—compounds advantages across model generations. Production data from building a Slack clone shows 60% of time and tokens spent on implementation, validation never succeeds on first go, and 50% of final code lines are tests with 90% coverage. The system is designed to improve with each model release by keeping orchestration logic in prompts and skills rather than hard-coded state machines.
