To be clear, you can totally use a claude code subscription in Zed. You just risk a chance that they're ban you and your subscription for it. Or you have to pay API pricing. Who's got money for that though, shit.
Signed up for Zed upon seeing this, signed in with GitHub, it failed instantly. Emailed support, they asked me to prove my ID because I was flagged as a bot. I immediately revoked access.
Fairly certain the support reply was from a bot, too. Meh.
/edit: occurred to me that OP meant Claude via ACP, not directly
