This episode of Exploring Modern AI in Tamil podcast walks through the steps to build a custom RAG agent with LangGraph.

- Summarizes foundational concepts like state, nodes, and edges for new developers.

- Explains how to visualise agent steps using the frontend stream hook.

- Describes how to integrate document retrieval tools with stateful message nodes.

- Describes how the agent decides between retrieval and direct response.

- Shows how to connect the graph output to a reactive frontend interface.

- Explains mapping node execution results to individual UI cards.

- Uses LangSmith trace data to spot and fix agent performance issues.

- Explains how to test graph nodes with irrelevant document inputs.

- Explains the process of grading retrieved content relevance before generating final answers.

- Details the logic for rewriting questions when retrieved context is insufficient.

- Discusses connecting these agents to external tools via Model Context Protocol.

- Explores how to maintain durable state across different user sessions.

- Focuses on best practices for debugging complex graph flows using LangSmith.

- Shares tips for optimizing node execution and state management.

- Includes a step-by-step plan for deploying these agents to production.

- Demonstrates how to implement persistent memory to improve agent consistency.

- Explains how useStream provides reactive access to node outputs and streaming tokens.

- Describes how to implement fault tolerance and time travel patterns for agents.

- Provides strategies for using LangSmith Deployment to monitor production agent performance.

- Discusses connecting diverse LangChain providers like Anthropic or Tavily for enhanced agent capabilities.
