Issue #481: Meta's new open source React design system — React Status

<p>The <code>astryx manifest --json</code> pattern is genuinely a landmark moment for frontend tooling. For years we’ve had OpenAPI for backends and machine-readable specs for APIs, but frontend design systems have been stuck in human-readable documentation that agents hallucinate from. Astryx finally gives AI coding agents an authoritative, structured contract for how to use components — and Meta’s <code>vibe-tests</code> harness proves they’re serious about measuring whether agents actually get it right. The five-dimensional static evaluation (Correctness, Accessibility, Code Quality, Efficiency, Maintainability) plus the Vision LLM-based design judge is the most rigorous approach to AI-generated UI quality I’ve seen. This is the bar for what “agent-ready” should mean.</p>
