What problem does it solve?
cmux skill eliminates the friction of manually coordinating multiple terminal panes and terminal/browser surfaces while an AI agent runs parallel tasks.
Core Features & Use Cases
- Multi-pane terminal orchestration: Spawn and manage panes, workspaces, and surfaces for isolated agent execution.
- Command-and-output control: Send commands/keystrokes to a specific surface and read screen output reliably.
- Workspace + browser side-by-side automation: Create workspaces and pair terminal panes with browser surfaces for web+code workflows.
- Subagent workflow support: Cleanly support spawn → run → read → cleanup patterns for parallel subagents.
Quick Start
Use the cmux skill to create a right split, run a build in the new pane, then read the output: "Create a split pane in cmux, send 'make build' to the new surface, press Enter, read the last 200 lines, and close the surface."
