In-vehicle voice assistant
Driver: 'find me a charging stop with a coffee place within 30 km on my route'. The agent calls the navigation API, the charging network and the nearby POI store, returns the best options ranked, and confirms before route change. Strict guardrails: never make jokes about driving conditions, never disparage charging networks, never offer political or controversial commentary. On-topic, accurate, brand-appropriate. The platform team can change the agent persona without a firmware update, because the prompt and retrieval scope are versioned separately in the Agent Registry.
What to measure
Task completion rate per voice request, guardrail violations per thousand sessions, and customer satisfaction with infotainment.
