やること
Azure AI Agent SeriviceでFunction Callingエージェントを作ってみる。
OpenWeatherAPIで天気の情報を取得してみる。
前提
- Azure AI Agent Serviceを構築済みであること
- OpenWeatherAPIを発行済みであること
Function callingエージェントを作る（GUI編）
Azure AI Agent Seriviceは、GUIベースでFunction Callingエージェントが作ることはできません！！（現時点では）
Function callingエージェントを作る（コード編）
MicrosoftからコードのサンプルがGithub上にあります。こちらをベースにします。
