Cmux Custom Sidebar
This builds a custom cmux sidebar from a plain language request. Instead of making the user learn SwiftUI syntax or config formats, it takes "show my workspaces and PRs" and writes the interpreted sidebar file directly into ~/.config/cmux/sidebars/, enables the beta flag, selects it, and iterates with hot reload. The sidebars bind to live cmux state (workspaces, tabs, git branches, PRs, clock) and run real cmux commands on tap. It's useful when someone wants their terminal multiplexer UI tailored to their workflow without touching Xcode or build tools. The skill handles the full loop: authoring, validation, selection, and fixing what looks off after the first render.

cmux Custom Sidebar
cmux renders custom sidebars from a small SwiftUI-style file at runtime: no Xcode, no build step, no signing. The file hot-reloads on save, binds to live cmux state (workspaces, tabs, git, PRs, clock), and runs real cmux commands on tap.
The person asking is describing a result ("a sidebar that shows my workspaces and lets me jump between them"), not an implementation. Make the engineering decisions for them; do not ask them about SwiftUI, files, or syntax.
This skill is the workflow summary. Read the complete authoring contract (every supported view, modifier, language feature, and data field) before writing a non-trivial sidebar:
