@mostra/react

The client runtime of Mostra, the agent artifact runtime. Artifacts import it for defineArtifact, the manifest an artifact declares in its entry:

import { defineArtifact } from "@mostra/react";

export const artifact = defineArtifact({ title: "Sidebar options", family: "review" });

export default function Page() {
  return <h1>Sidebar options</h1>;
}

Artifacts don't install it: every Mostra build resolves it from the warm set. Fields, submissions, actions and live data arrive in later releases. Apache-2.0.
