Author a Copilot CLI extension that opens a native desktop window (webview) and exchanges live messages with page-side JavaScript. Use this skill whenever the user wants to build, scaffold, or extend a Copilot CLI extension that needs a GUI, a dashboard, an interactive panel, an HTML/React UI driven by the agent, real-time visualizations updated from the extension, or two-way communication between agent code and a webview page. Trigger this skill on requests like "make an extension that shows a UI", "open a window from my extension", "build a Copilot dashboard", "show a webview", "render React from my Copilot extension", "let the page call back into my extension", or anything that combines a Copilot CLI extension with visual/interactive output.
