Preview Dev — Frontend & Fullstack Development with Live Preview

1. Analyze user requirements and determine the project type (e.g., static HTML, React app, backend API). 2. Write or modify code to create a runnable project. 3. Check the code to confirm the correct port number for the application. 4. Start the preview server using `preview_serve` with the correct directory, command, and port. 5. Verify the preview is healthy by checking the `health_check` field in the response. 6. If issues are reported, diagnose using `preview_check` and `read_file`, then fix in place using `edit_file`. 7. Restart the preview with `preview_stop` and `preview_serve` using the same directory and port. 8. If the user wants to share the preview publicly, use `community_publish` to create a public URL.
