Scaffolds a complete Next.js app with Stream's chat, video, feeds, or moderation SDKs, or drops them into an existing project. The full flow runs steps 0-7: auth check, Shadcn theme picker, Next.js scaffold, Stream CLI wiring for API keys, SDK installs, and component blueprints. It's opinionated about the stack (Next.js, Tailwind, Shadcn) but handles both greenfield builds and enhancement of existing codebases. The trust model is transparent: it lists every network call (npx shadcn, npm installs, optional frontend skill packs) with publisher info before executing, and gates third-party skills behind explicit consent. Useful when you want Stream products wired end-to-end without stitching docs yourself, though the rigid scaffolding means you're committing to their stack choices upfront.
