Decision

What the current evidence supports

Human editorial judgment · 2026-08-20

Adopt with guardrails

Why
Officially production-blessed, now embedded in the 2026-07-28 spec, with broad client support and real shipped apps, but documented cross-host CSP, streaming-readiness, and SDK-coverage defects mean it needs guardrails and multi-host testing, not blind adoption.
Next
Prototype one ephemeral, single-purpose ui:// widget behind a host-abstraction layer; test it explicitly on Claude.ai AND ChatGPT and verify CSP frameDomains before relying on external-origin iframes; prefer TypeScript for the UI bundle given the SDK gap; avoid embedding full apps.
