auto sig = axllm::s("email:string -> priority:class \"high, normal, low\"");
Name the capability
lookup gives the model and traces a stable tool name.
Type the boundary
ticketId and the JSON result use the same field vocabulary as Ax programs.
Keep execution in your app
The handler owns the real lookup and returns the declared result.
