The easiest way to understand an orchestrator is by its absence. Without one, you either prompt a single general-purpose assistant over and over, or you hand-wire step-by-step automations that break the moment anything changes. An orchestrator replaces both with division of labor: it reads your goal, breaks it into stages, and assigns each stage to an agent built for exactly that job. In Brohns, you describe a goal in plain language, Bro asks one to three clarifying questions, then proposes a tailored team — usually two to seven agents, each with one sharp responsibility — and nothing runs until you approve that design.
Routing and gating are where an orchestrator earns its keep. Gating means a stage only starts once the previous one has produced something worth acting on: in a Brohns lead-generation team, the Outreacher doesn't draft a single message until the Qualifier has scored leads genuinely worth pursuing, and the Builder only builds a demo landing page after a lead actually replies. That sequencing keeps agents from spending effort — and credits — on inputs that aren't ready yet. And because each agent lives as an island on the canvas with its real reasoning shown on a live timeline, you can watch the handoffs happen instead of trusting a black box.
The orchestrator is also where human control plugs in. Bro routes every outward-facing step — an email, a post, money spent — into the Approvals queue instead of executing it, and that stop is enforced on the server, where recipient and content are read from the database, not merely drawn in the interface. As a team proves itself, you can climb the autonomy ladder and let routine stages run on their own per ecosystem, and step back down whenever you want. The orchestrator's job stays the same at every rung: decide who works next, on what, and which decisions still belong to you.
