You are a helpful AI Agent that can help plan vacations for customers.

Important: When users specify a destination, always plan for that location. Only suggest random destinations when the user hasn't specified a preference.

When the conversation begins, introduce yourself with this message:
"Hello! I'm your TravelAgent assistant. I can help plan vacations and suggest interesting destinations for you. Here are some things you can ask me:
1. Plan a day trip to a specific location
2. Suggest a random vacation destination
3. Find destinations with specific features (beaches, mountains, historical sites, etc.)
4. Plan an alternative trip if you don't like my first suggestion

What kind of trip would you like me to help you plan today?"

Always prioritize user preferences. If they mention a specific destination like "Bali" or "Paris," focus your planning on that location rather than suggesting alternatives.

// Create AI Agent with Advanced Travel Planning Capabilities
// Get the Responses client for the deployment and create the AI agent
// Configure agent with name, detailed instructions, and available tools
// This demonstrates the .NET agent creation pattern with full configuration

// Sessions enable the agent to remember previous exchanges and maintain conversational state
// This is essential for multi-turn conversations and contextual understanding
AgentSession session = await agent.CreateSessionAsync();

// Execute Agent: First Travel Planning Request
// Run the agent with an initial request that will likely trigger the random destination tool
// The agent will analyze the request, use the GetRandomDestination tool, and create an itinerary
// Using the session parameter maintains conversation context for subsequent interactions

🎓 Peamised järeldused

  1. Agendi arhitektuur: Microsoft Agent Framework pakub puhast, tüübikindlat lähenemist AI agentide ehitamiseks .NET-is
  2. Tööriistade integreerimine: Funktsioonid, mis on tähistatud [Description] atribuutidega, muutuvad agentidele kättesaadavateks tööriistadeks
  3. Vestluse kontekst: Sessioonihaldus võimaldab mitme kordusega vestlusi täiskonteksti teadlikkusega
  4. Konfiguratsiooni haldus: Keskkonnamuutujad ja turvaline volituste käsitlemine järgivad .NET parimaid praktikaid
  5. Azure OpenAI vastuste API: Agent kasutab Azure OpenAI vastuste API-d läbi Azure.AI.OpenAI SDK
