Sometimes I’ll start a session, and then want to branch a task into a new session in a new pane.

For example, at the end of my daily briefing, the agent will offer to help with several unrelated workstreams:

I want to start several of these tasks in parallel, in independent sessions that I can easily observe and chat with.

My /pane skill makes that easy.

I’ll say: do tasks 1 and 3 in new panes and it’ll write a handoff prompt, spawn a new pane, and ask the agent to get to work.

I have similar skills to spawn new tabs and windows.
