🏗️ Day 1-2: Agentic RAG Foundation

1.1 Agentic RAG Core Architecture

Target Implementation Structure:

class AgenticRAGSystem:
    def __init__(self, tenant_id: str):
        self.tenant_id = tenant_id
        self.agents = self._initialize_agents()
        self.coordinator = AgentCoordinator()
        self.memory_system = AgentMemorySystem()
    
    def _initialize_agents(self) -> Dict[str, BaseAgent]:
        return {
            'researcher': ResearchAgent(),
            'analyzer': AnalysisAgent(), 
            'synthesizer': SynthesisAgent(),
            'validator': ValidationAgent()
        }

Implementation Guidelines:

• Agent Isolation: Each agent operates in isolated context with tenant boundaries
• Memory Persistence: Implement Redis-based agent memory with TTL
• State Management: Use state machines for agent lifecycle management
• Error Recovery: Implement circuit breaker pattern for agent failures
• Performance Monitoring: Add Prometheus metrics for agent performance

1.2 Multi-Agent Communication Protocol

Message Structure:

class AgentMessage:
    def __init__(self, sender: str, recipient: str, message_type: str, payload: dict):
        self.sender = sender
        self.recipient = recipient
        self.message_type = message_type
        self.payload = payload
        self.timestamp = datetime.utcnow()
        self.correlation_id = str(uuid.uuid4())

Best Practices:

• Message Queuing: Use Redis Streams for reliable agent communication
• Correlation Tracking: Implement correlation IDs for request tracing
• Load Balancing: Distribute agent workload based on capacity
• Health Checks: Regular agent health monitoring and auto-restart
• Resource Limits: Implement CPU/memory limits per agent

    async def make_decision(self, context: dict, options: List[dict]) -> Decision:
        confidence_scores = await self._evaluate_options(context, options)
        best_option = self._select_best_option(confidence_scores)
        
        if best_option.confidence < self.confidence_threshold:
            return await self.fallback_strategy.execute(context)
        
        return best_option

            for thought in current_thoughts:
                if depth < self.max_depth - 1:
                    new_thoughts = await self.expansion_function(thought)
                    tree.add_children(thought, new_thoughts[:self.max_breadth])

        # Step 3: Reasoning Execution
        reasoning = await self._execute_reasoning(context_building)
        chain.add_step(reasoning)
        
        # Step 4: Validation
        validation = await self._validate_reasoning(reasoning)
