Create Canvas App | Agent Skills Atlas

About this skill

Build a GitHub Copilot App canvas extension the right way, fast. Use when the user wants to create, scaffold, or improve an interactive canvas (a side-panel UI the agent can open and drive) — dashboards, editors, trackers, boards, document/preview surfaces. Provides a no-build Preact + htm kit with live SSE state, durable per-user storage, Primer theming, and the official GitHub Lucide icon set, plus a generator that stamps a working canvas in one command. Do NOT use for non-canvas extensions (plain agent tools) or for shipping web apps unrelated to Copilot canvases.
