Setting Up AutoGen Multi-Agent Environment

The initialization of an AutoGen environment requires careful configuration of multiple agents with specific roles and capabilities. This setup establishes the foundation for nested conversations between AI agents, enabling complex interactions and task delegation.

import autogen
from autogen import AssistantAgent, UserProxyAgent, config_list_from_json

# Configure agents with specific roles and capabilities
config_list = config_list_from_json("OAI_CONFIG_LIST")
llm_config = {"config_list": config_list, "seed": 42}

# Initialize the assistant agents
outline_agent = AssistantAgent(
    name="outline_agent",
    llm_config=llm_config,
    system_message="Expert in creating detailed article outlines"
)

writer_agent = AssistantAgent(
    name="writer_agent",
    llm_config=llm_config,
    system_message="Specialized in writing technical content"
)

reviewer_agent = AssistantAgent(
    name="reviewer_agent",
    llm_config=llm_config,
    system_message="Expert in reviewing and improving content"
)

# Initialize the user proxy agent
user_proxy = UserProxyAgent(
    name="user_proxy",
    code_execution_config={"work_dir": "coding"}
)

Implementing Nested Chat Architecture

Creating a nested chat structure requires defining communication pathways and interaction protocols between agents. This architecture allows agents to engage in focused sub-conversations while maintaining the overall context of the task.

class NestedChatManager:
    def __init__(self, primary_agents, secondary_agents):
        self.primary_agents = primary_agents
        self.secondary_agents = secondary_agents
        self.chat_history = []
        
    def create_nested_conversation(self, initiator, participants):
        conversation = {
            'initiator': initiator,
            'participants': participants,
            'messages': [],
            'status': 'active'
        }
        return conversation
    
    def send_message(self, sender, message, conversation):
        msg = {
            'sender': sender,
            'content': message,
            'timestamp': datetime.now()
        }
        conversation['messages'].append(msg)
        
    def resolve_conversation(self, conversation):
        summary = self._generate_summary(conversation)
        conversation['status'] = 'resolved'
        return summary
    
    def _generate_summary(self, conversation):
        messages = [msg['content'] for msg in conversation['messages']]
        return ' '.join(messages)

Configuring Inter-Agent Communication

The communication flow between agents must be carefully orchestrated to maintain context and ensure efficient information exchange. This implementation defines the messaging protocol and handling of nested conversations between multiple agents.

class AgentCommunicationProtocol:
    def __init__(self, agents):
        self.agents = agents
        self.active_conversations = {}
        self.message_queue = Queue()
        
    def initiate_conversation(self, sender, recipients, context):
        conversation_id = str(uuid.uuid4())
        self.active_conversations[conversation_id] = {
            'participants': [sender] + recipients,
            'context': context,
            'messages': []
        }
        return conversation_id
    
    def send_message(self, conversation_id, sender, message):
        if conversation_id not in self.active_conversations:
            raise ValueError("Invalid conversation ID")
            
        message_obj = {
            'sender': sender,
            'content': message,
            'timestamp': time.time()
        }
        
        self.active_conversations[conversation_id]['messages'].append(message_obj)
        self.message_queue.put((conversation_id, message_obj))
        
    def get_conversation_history(self, conversation_id):
        return self.active_conversations.get(conversation_id, {}).get('messages', [])

Article Generation Pipeline

The article generation process involves multiple stages where agents collaborate through nested conversations. Each agent contributes its expertise while maintaining communication through the established protocol.

class ArticleGenerationPipeline:
    def __init__(self, outline_agent, writer_agent, reviewer_agent):
        self.outline_agent = outline_agent
        self.writer_agent = writer_agent
        self.reviewer_agent = reviewer_agent
        self.comm_protocol = AgentCommunicationProtocol([
            outline_agent, writer_agent, reviewer_agent
        ])
        
    async def generate_article(self, topic):
        # Generate outline
        outline_conv = self.comm_protocol.initiate_conversation(
            self.outline_agent, [], {'topic': topic}
        )
        outline = await self.outline_agent.generate_outline(topic)
        
        # Write initial draft
        writer_conv = self.comm_protocol.initiate_conversation(
            self.writer_agent, [self.reviewer_agent], 
            {'outline': outline}
        )
        draft = await self.writer_agent.write_draft(outline)
        
        # Review and revise
        review_result = await self.reviewer_agent.review_content(draft)
        final_article = await self.writer_agent.incorporate_feedback(
            draft, review_result
        )
        
        return final_article

Implementing the Outline Agent

The Outline Agent utilizes advanced NLP techniques to generate structured article outlines. It processes the topic and creates a hierarchical structure that guides the content creation process.

class OutlineGenerator:
    def __init__(self, model_config):
        self.nlp_processor = NLPProcessor()
        self.knowledge_base = KnowledgeBase()
        
    async def generate_outline(self, topic):
        # Extract key concepts
        concepts = self.nlp_processor.extract_key_concepts(topic)
        
        # Structure hierarchy
        hierarchy = {
            'main_topic': topic,
            'sections': []
        }
        
        for concept in concepts:
            subtopics = self.knowledge_base.get_related_topics(concept)
            section = {
                'title': concept,
                'subtopics': subtopics,
                'depth': self._calculate_depth(subtopics)
            }
            hierarchy['sections'].append(section)
            
        return self._format_outline(hierarchy)
        
    def _calculate_depth(self, subtopics):
        return min(len(subtopics), 3)  # Limit depth to 3 levels
        
    def _format_outline(self, hierarchy):
        formatted = []
        for section in hierarchy['sections']:
            formatted.append(f"# {section['title']}")
            for subtopic in section['subtopics']:
                formatted.append(f"## {subtopic}")
        return '\n'.join(formatted)

Writer Agent Implementation

The Writer Agent transforms outlines into coherent content using advanced language processing and generation techniques. It maintains context awareness and implements content generation strategies based on the provided outline structure.

class WriterAgent:
    def __init__(self, llm_config):
        self.content_generator = ContentGenerator(llm_config)
        self.context_manager = ContextManager()
        self.style_validator = StyleValidator()
        
    async def write_section(self, section_outline, context):
        section_content = {
            'content': '',
            'metadata': {},
            'citations': []
        }
        
        # Generate initial content
        raw_content = await self.content_generator.generate(
            outline=section_outline,
            context=context,
            style_guide=self.style_validator.get_rules()
        )
        
        # Validate and enhance content
        enhanced_content = self.style_validator.check_and_enhance(raw_content)
        section_content['content'] = enhanced_content
        
        # Track context for nested sections
        self.context_manager.update_context(section_outline, enhanced_content)
        
        return section_content

    async def process_outline(self, full_outline):
        article_sections = []
        current_context = self.context_manager.get_initial_context()
        
        for section in full_outline.sections:
            section_content = await self.write_section(section, current_context)
            article_sections.append(section_content)
            current_context = self.context_manager.update_context(section)
            
        return self.compile_article(article_sections)

Reviewer Agent Core Logic

The Reviewer Agent implements sophisticated content analysis algorithms to evaluate and improve article quality. It focuses on coherence, accuracy, and adherence to style guidelines while maintaining nested conversation context.

class ReviewerAgent:
    def __init__(self, review_config):
        self.quality_checker = QualityChecker()
        self.feedback_generator = FeedbackGenerator()
        self.revision_tracker = RevisionTracker()
        
    async def review_content(self, content, review_criteria):
        # Perform deep content analysis
        quality_metrics = await self.quality_checker.analyze(content)
        
        # Generate structured feedback
        feedback = self.feedback_generator.create_feedback(
            content=content,
            metrics=quality_metrics,
            criteria=review_criteria
        )
        
        # Track revision suggestions
        revision_id = self.revision_tracker.create_revision(
            original_content=content,
            feedback=feedback,
            timestamp=datetime.now()
        )
        
        return {
            'revision_id': revision_id,
            'feedback': feedback,
            'metrics': quality_metrics,
            'suggestions': self._generate_suggestions(feedback)
        }
    
    def _generate_suggestions(self, feedback):
        return [
            {
                'type': issue['type'],
                'location': issue['location'],
                'suggestion': self.feedback_generator.get_improvement(issue)
            }
            for issue in feedback['issues']
        ]

Nested Chat State Management

Implementing robust state management for nested conversations ensures proper context tracking and seamless transitions between different levels of agent interaction.

class NestedChatStateManager:
    def __init__(self):
        self.conversation_stack = []
        self.context_registry = {}
        self.state_transitions = {}
        
    def push_conversation(self, conversation_id, participants, context):
        conversation_state = {
            'id': conversation_id,
            'participants': participants,
            'context': context,
            'parent': self.get_current_conversation(),
            'status': 'active'
        }
        
        self.conversation_stack.append(conversation_state)
        self.context_registry[conversation_id] = context
        return conversation_state
        
    def pop_conversation(self):
        if self.conversation_stack:
            completed_conv = self.conversation_stack.pop()
            self._handle_completion(completed_conv)
            return completed_conv
        return None
    
    def get_current_conversation(self):
        return self.conversation_stack[-1] if self.conversation_stack else None
    
    def _handle_completion(self, conversation):
        parent_id = conversation.get('parent', {}).get('id')
        if parent_id:
            self._update_parent_context(parent_id, conversation)
            
    def _update_parent_context(self, parent_id, child_conversation):
        if parent_id in self.context_registry:
            self.context_registry[parent_id].update({
                'child_results': child_conversation.get('results')
            })

Metrics and Performance Monitoring

This implementation focuses on tracking and analyzing the performance of nested chat interactions, providing insights into agent efficiency, conversation quality, and system optimization opportunities.

class PerformanceMonitor:
    def __init__(self):
        self.metrics_store = MetricsDatabase()
        self.conversation_analyzer = ConversationAnalyzer()
        self.performance_metrics = defaultdict(dict)
        
    async def track_conversation(self, conversation_id, agents):
        start_time = time.time()
        metrics = {
            'response_times': [],
            'interaction_depth': 0,
            'resolution_success': False,
            'agent_contributions': defaultdict(int)
        }
        
        async def monitor_interaction(interaction):
            # Track response time
            response_time = time.time() - interaction['start_time']
            metrics['response_times'].append(response_time)
            
            # Track agent contributions
            metrics['agent_contributions'][interaction['agent_id']] += 1
            
            # Analyze interaction quality
            quality_score = self.conversation_analyzer.analyze_quality(
                interaction['content']
            )

            }

        }

Error Handling and Recovery System

Robust error handling mechanism for managing failures in nested conversations, implementing recovery strategies, and maintaining system stability during complex agent interactions.

class ErrorHandler:
    def __init__(self):
        self.error_registry = {}
        self.recovery_strategies = {}
        self.state_backup = StateBackupManager()

        error_id = str(uuid.uuid4())
        
        try:
            # Log error details
            self.error_registry[error_id] = {
                'error': error,
                'context': context,
                'timestamp': time.time()
            }
            
            # Determine recovery strategy
            strategy = self._select_recovery_strategy(error, context)
            
            # Execute recovery
            recovery_result = await self._execute_recovery(strategy, context)
            
            if recovery_result['success']:
                await self._restore_conversation_state(
                    context['conversation_id'],
                    recovery_result['restored_state']
                )
            else:
                await self._initiate_fallback_procedure(context)
                
            return recovery_result
            
        except Exception as e:
            # Critical error handling
            await self._handle_critical_error(e, context)
            raise SystemRecoveryError(f"Failed to recover from error: {str(e)}")
    
    async def _execute_recovery(self, strategy, context):
        backup_state = await self.state_backup.get_latest_backup(

        )
        
        return await strategy.execute(
            error_context=context,
            backup_state=backup_state
        )
