defmodule Object.LLMIntegration do
  @moduledoc """
  Enhanced LLM integration for AAOS objects using DSPy.
  
  This module enables objects to:
  1. Respond to messages using LLM-powered natural language
  2. Generate contextual responses based on object state and history
  3. Adapt their communication style based on interaction patterns
  4. Use structured reasoning for complex decisions
  
  Usage Examples:
  
      # Basic LLM response generation
      {:ok, response} = Object.LLMIntegration.generate_response(object, incoming_message)
      
      # Contextual conversation
      {:ok, response} = Object.LLMIntegration.conversational_response(object, message, conversation_history)
      
      # Goal-oriented reasoning
      {:ok, plan} = Object.LLMIntegration.reason_about_goal(object, goal, current_situation)
