package com.jscode.tool.service;

@Service
public class ToolService {

  private final ChatClient chatClient;


  public ToolService(ChatClient.Builder chatClientBuilder,
                     Advisor[] advisors,
                     @Value("${app.chat.default-system-prompt:}") String systemPrompt,
                     Tools tools) {
      this.chatClient = chatClientBuilder
              .defaultSystem(systemPrompt)
              .defaultTools(tools)
              .defaultOptions(ToolCallingChatOptions.builder()
                              .temperature(0.2).build().mutate())
              .defaultAdvisors(advisors)
              .build();


  }

  private ChatClient.ChatClientRequestSpec createRequest(String conversationId, Prompt prompt){
      return chatClient.prompt(prompt)
              .advisors(advisorSpec -> advisorSpec.param(ChatMemory.CONVERSATION_ID, conversationId));
  }

  public Flux<String> stream(String conversationId, Prompt prompt){
      return createRequest(conversationId, prompt).stream().content();
  }

  public ChatResponse call(String conversationId, Prompt prompt){
      return createRequest(conversationId, prompt).call().chatResponse();
  }
}
