Understand the workflow.
Sales systems repeat a relatively small set of operations across a large number of conversations. A good agent needs to understand the request, work within the available APIs, and leave the system in the right state.
Define the quality bar.
Use a bounded task and an inspectable target state. Evaluate the full action, including tool selection and arguments, rather than judging whether the response sounds plausible.
Improve the route.
Begin with the prompt, schema, and tool-call adapter. Compare model routes on the same task slices. Use specialist training when repeated failure modes and accepted corrections justify it.
Keep frontier capability.
Keep frontier reasoning for unfamiliar workflows, complex ambiguity, and cases where the strongest model changes the result.
