Structured UI output vs raw JSX
Why agent-generated product interfaces are safer and easier to reuse when models emit structured A2UI-style payloads instead of raw JSX or HTML.
Structured output gives agents a contract
Raw JSX can be expressive, but it is hard for an agent to inspect reliably. A structured A2UI payload gives the server and client a typed contract for components, layout, data, and actions.
Validation happens before rendering
Gravity AI UI validates the composed payload before rendering through trusted Gravity UI components. That avoids arbitrary markup execution and keeps generated screens inside a known design-system boundary.
Reuse is easier to automate
Structured UI output can be searched, fetched through MCP, summarized in markdown, converted into a React export, and cited by assistants. Raw JSX usually needs extra parsing before an agent can trust it.
Raw JSX still fits code-first prototyping
Raw JSX is useful when the job is direct component code drafting. Structured output is the better default when the workflow needs A2UI messages, OpenAPI docs, MCP tools, public gallery context, and repeatable agent inspection.
