You use one signature vocabulary across generation, tools, agents, flows, and optimization. That shared meaning makes later Ax features easier to combine.

See the idea in context
auto qa = axllm::ax("question:string -> answer:string, confidence:number");
Separate input from output
The arrow puts message on the input side and the generated fields on the output side.
Use a class for fixed choices
category cannot drift beyond billing, technical, or other.
Reuse the parsed signature
s() creates a contract you can inspect, share, and compose.
