Harness: a piece of equipment with straps and belts, used to control or hold in place a person, animal, or object.

So yes the generel meaning applies to test setup and running and also to the agent cli which is the harness for the model.

No, an agent cli is no harness. You have to provide a harness for an agent by yourself, otherwise it will run free. Which is called vibe coding. Free as you wish, without any harness.

[teknologist]

An agent cli provides a sandbox, with permission systems and auto command classifiers. That’s part of the harness.
