I'm a big fan of Zed but tbf I'm just using Claude Code + Nvim nowadays. Zed's problem with their Claude integration is that it will never be as good as just using the latest from Claude Code.
The integration in Zed is limited by what the Claude Code SDK exposes. Since about half of the /commands are missing from the SDK, they don’t show up in Zed.
I think ACP was a good strategic move by Zed, but all I personally really need is Claude Code in a terminal pane with diffs of proposed edits in the absolutely wonderful multibuffer view
