At the moment there is no official support for ACP usage outside of the few editors listed on Antigravity’s website. While I’m sure I could easily get the Zed or VSCode integration to work with my editor of choice I do not wish to risk violating the TOS and having my Google Account deleted or locked out.
So please, allow us who use Emacs (or NeoVIM, or whatever) to have official access to ACP support so that we can integrate it with our editor of choice without losing peace of mind.
