Cockpit 0.7 is out, with a new bay: Subagents.
OpenCode shows a subagent as one line in the chat. Now each one sits in the sidebar with what it's doing right now, and a click opens its whole run beside the conversation.
Your coding agent can't run a dev server.
It runs it, blocks, and waits. Or backgrounds it and loses it.
I spent two weeks fixing that for OpenCode. It's called Cockpit.
