no1msd/seance — reverse-engineered prompt

Build me a Linux desktop terminal app for managing multiple AI coding agents at once. I want it to feel like a terminal multiplexer, but instead of a fixed grid, panes should sit in a horizontal scrolling strip so I can move through long Claude Code, Codex, or similar sessions naturally.

It should automatically notice when an agent is running inside a pane and show its status in a sidebar, like working, idle, finished, or waiting for my approval. When an agent needs permission or finishes a task, send a desktop notification and mark it as unread until I check it.

Make it native, not Electron. Use GTK style integration, support Wayland and X11, and make the terminal rendering fast. Include workspaces, tabs inside columns, session restore after restart, a command palette, focus follows mouse, and no telemetry.

Also add a command line control tool so scripts and agents can create panes, switch workspaces, send input, read output, and return JSON. Keep setup simple with zero config.
