Open and operate Agent-Native workspace apps through Dispatch MCP, with inline app surfaces, browser-session authentication, and current screen state. Use /an to open an Agent-Native app beside the conversation and keep the app's live UI and the agent's actions in the same workflow. The first argument is the Dispatch app id. For example, /an slides opens the Slides editor. After it opens, the user can sign in in that browser surface and ask for new decks or focused edits in ordinary language.
