omdsh-sidechat

You are deep in the harness web UI, watching a long multi-turn tool-call chain unfold, and a thought pops up: what is that function actually doing? The only place you can ask is the main conversation below, which is live, accumulating context, and will carry your quick question into every subsequent turn. Your eyes leave what you were reading, your attention shifts, and the cost is paid twice.
omdsh-sidechat exists to delete that cost. Press Cmd+L and a standalone conversation appears right where you are: its own session, its own history, its own workspace, while the main conversation's context stays untouched. The panel renders only text answers; reasoning blocks and tool-call blocks are never shown, and while the model is still working you see a single line that reads Deep diving.... You can have the side conversation embed the current conversation's context as a true read-only fork, or keep it fully independent. By default the side conversation is hidden from the sidebar until you press Save; until then it occupies no visible space. The panel is draggable, remembers its position across reloads, and keeps an icon in the session header, all without perturbing the main conversation in any way.
Built for developers who live in the harness web UI, supervise long multi-step tool chains, and need to pop out and ask a quick question without polluting their working context. It does not change how you supervise; it simply extracts the act of asking a small question from the main workflow so the primary conversation stays clean.
