Output-First Architecture (OFA) is a method for building AI agents by defining the required output — format, quality, constraints — before selecting tools or designing the process. It is the fastest path from "AI idea" to working automation for non-engineers.
Output-First Architecture (OFA)
Before asking "which AI tool should I use?", OFA asks "what exactly should the output look like?" Defining the output first eliminates 80% of agent design errors and makes the workflow auditable and improvable without touching the underlying model.
