I read through the docs. There is no mention of whether programmatic usage or Agent Client Protocol will continue be supported in Antigravity CLI.

People are saying it doesn't have ACP at all. We don't know if that's an intentional decision or a temporary gap.

I don't think it's happening because Antigravity's concurrent core architecture is incompatible with ACP. For example Antigravity supports running multiple agent and process threads in the background while keeping the main thread free for conversation. ACP can't really support that.

To put it in ad speak, ACP is too basic for how advanced the agy harness is
