stream-builder
The framework-agnostic Stream builder (Steps 0-7 scaffold + enhance + Video audit), being extended to support app kinds beyond web. Use ONLY when the user explicitly names 'stream-builder' or '/stream-builder'. Web React / Next.js work - 'build me a chat app', 'scaffold', 'create a new ...', 'add Chat/Video/Feeds to this app', 'integrate Video', livestreaming, video conferencing, team messaging, direct messaging, social feed - defaults to the stream-react skill, not this one. Not auto-selected for generic web build requests.

W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill explicitly runs `npx shadcn@latest ...` during scaffold (Step 3 Task A), which fetches and executes remote code from the shadcn UI package (publisher referenced at https://github.com/shadcn-ui/ui) as a required runtime dependency for scaffolding the project.
