(* The Vercel AI SDK convention for providers that don't natively enforce JSON Schema:
   synthesize a tool called "json" whose inputSchema is the caller's schema, force the
   model to call it, and decode the response from the tool_use args. Upstream
   [@ai-sdk/anthropic] uses this exact name; changing it would break interop. *)
