[vohk]

As already mentioned, this is the noun use but also different connotations.

To my thinking, to orchestrate or steer suggests a conductor or driver, an outside entity providing direction. A master agent creating and directing subagents could reasonably be called an orchestrator.

A harness is what the horse wears to pull a cart, or what connects a pilot to a parachute and provides the controls to tug on and steer. It might provide guidance or capability, but not active direction. It's also a fairly common use in hardware ( a wire harness) and software (a testing harness) already.
