VS @code is bringing Copilot Canvases into the Agent experience. The concept is similar to Canvases in the GitHub Copilot app: a shared interactive surface where both the human and the agent can work on the same artifact. Think dashboards, Kanban boards, plans, triage boards, etc. But there is an interesting difference under the hood. VS Code isn't waiting for Canvases to become part of the canonical Agent Host Protocol. It is shipping a VS Code-specific transport first, which lets them experiment with the primitive without committing the whole AHP ecosystem to the API yet. And you can actually create one yourself. Start an agent session and run: /create-canvas Then describe what you want, for example: `Create an agentic Kanban canvas where I can create, assign and move cards, and where you can also update the board.` The agent builds the canvas and opens it in the Sessions UI. You can then keep iterating on the UI, state and capabilities from the agent. For a team canvas, it can live under .github/extensions. Personal canvases can live under ~/.copilot/extensions.
