ai-core/structured-outputs
Type-safe JSON schema responses from LLMs using outputSchema on chat() and useChat(). Supports Zod, ArkType, and Valibot schemas. The adapter handles provider-specific strategies transparently — never configure structured output at the provider level. Pass stream:true alongside outputSchema for incremental JSON deltas + a terminal validated object via the `structured-output.complete` event. Every assistant turn in useChat carries its own typed `StructuredOutputPart` on `messages[i].parts`, so multi-turn structured chats preserve history automatically — partial/final derive from the latest assistant turn's part. convertSchemaToJsonSchema() for manual schema conversion.

1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
In Pattern 4/5/6, the required runtime workflow (via `useChat`/SSE endpoint) ingests the user-controlled `messages` sent by the client and passes them into `chat({ ... outputSchema })`, so outsider-authored free text can be processed by the model without selecting a specific trusted item first.
