About cmux-custom-sidebar

cmux-custom-sidebar
Build a custom cmux sidebar from a plain-language request
Cmux-custom-sidebar builds a custom sidebar for the cmux app from a plain-language request. You describe the result you want, such as a sidebar that shows your workspaces and lets you jump between them, or one that also shows tabs, pull requests or a clock. The skill makes the engineering decisions for you, so you do not need to know about SwiftUI, files or syntax. Under the hood, cmux renders custom sidebars from a small SwiftUI-style file at runtime. There is no Xcode project, no build step and no signing. The file hot-reloads when you save it, binds to live cmux state such as workspaces, tabs, git status, pull requests and the clock, and runs real cmux commands when you tap an item. The skill is a workflow summary, and it tells the agent to read the full authoring contract, which lists every supported view, modifier and data field, before writing a non-trivial sidebar. It is listed on skills.sh as part of the cmux project by manaflow-ai.
