The multi-agent architecture behind reliable missions
Blog post from Factory
Factory’s Luke Alvoeiro describes a multi-agent coding architecture designed to reduce the supervision burden of coordinating multiple AI agents by separating planning, implementation, and validation into distinct roles with explicit handoffs and shared state. Orchestrators define goals, milestones, boundaries, and completion conditions before work begins; workers receive bounded assignments with sufficient context; and independent validators test behavior against requirements rather than merely confirming implementation choices. The approach emphasizes detailed validation contracts, reliable application setup, isolated test data, and structured handoffs that preserve completed work, failures, command results, untested conditions, and evidence for later review. To avoid conflicting edits and inconsistent design decisions, implementation tasks should generally proceed serially, while read-only research and reviews can run in parallel when they do not alter shared code. The framework also recommends evaluating models according to their specific roles and keeping reusable prompt-based procedures inspectable and testable, while maintaining stable acceptance criteria even as orchestration methods evolve.
