cmux is a Ghostty-based macOS native terminal multiplexer that allows AI agents to control multiple terminal surfaces and browser windows via CLI or Unix sockets.

Can I track build progress with cmux?

Yes, cmux supports sidebar metadata commands to display progress bars, status icons, and logs for real-time monitoring of background tasks.

How does the browser automation feature work?

It provides commands to open browser surfaces, navigate URLs, interact with DOM elements, and take screenshots directly within the terminal environment.

What happens if the cmux CLI is not installed?

The skill includes a fallback mechanism to standard terminal operations, though advanced features like pane splitting and browser control will be unavailable.

Does this skill work on Windows or Linux?

cmux is currently designed as a macOS native tool leveraging Ghostty features; it may have limited functionality on other operating systems.
