I'm not too familiar with Warp so can someone help clarify for me:

Is Warp a terminal? Or an agent harness? Or both?

Warp as a terminal to me seems less interesting than having a well built agent harness like OpenCode that can effectively use many different models. If it's both, is there any advantage to having them be the same thing? Like, is there any way your harness can be smarter if it is also tightly integrated in your terminal? Or is it just something that Warp happens to do both of?
