muxy

Best-practice guide for authoring a Muxy extension — how it should look and behave so it reads as a native part of the app. Covers theming (follow the theme, never hardcode colors), the sizing scale, and which surface to use. Mechanics (manifest fields, permissions, the window.muxy API) live in the linked docs.

How to drive the Muxy macOS terminal multiplexer from a shell with the `muxy` command — open projects, switch projects/worktrees/tabs, build split layouts, send input to panes, and read visible terminal output. Use this when you are an agent running inside a Muxy pane (or any script on the same machine) and want to control the workspace instead of asking the user to click. Mechanics and the security model live in the linked docs.
