[synthesis] How do you build multi-agent orchestration without collapsing into spaghetti routing logic?

Use a minimal primitive set: agents with instructions/tools, handoffs that transfer control of the loop to a specialist agent, and guardrails that run as concurrent tripwires. Reserve heavy workflow engines for durable state, branching, or human review.

Journey Context:
OpenAI's Agents SDK \(the supported successor to Swarm\) demonstrates that multi-agent systems do not require a heavy graph framework. A handoff is not a function call returning a value—it transfers the entire conversation to another agent. Guardrails are not generic content filters; they are single-purpose checks that can block or flag input/output concurrently with the main run. The SDK is intentionally lightweight and sits on the Responses API. The common mistake is using it for long-running stateful workflows; for that, pair it with a durable orchestrator like LangGraph.
