Changes are reflected in real-time as the AI agent or you make updates. How to access: The Preview is visible by default in the main workspace view, displaying your app in an iframe. Key features: * Real-time updates: See changes immediately as code is updated * Full interactivity: Click, navigate, and test features just like end users would * Open in new tab: Click the button above the preview to open your app in a separate browser window (useful for OAuth flows and full-screen testing) * View logs: Access console logs and error messages using the logs button above the preview Tips: * Open preview in a new tab when testing OAuth integrations (Google, GitHub, etc.) as they may be blocked in iframe view * Use the preview to verify changes before deployment * The preview shows your development environment - deployment is separate --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.riff.ai/archive/features-legacy-databutton-web-app-builder/workspace-features/preview.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
