Course Outline

LangGraph and Agent Patterns: A Practical Primer

  • Distinguishing graphs from linear chains: when and why to choose each.
  • Understanding agents, tools, and planner-executor loops.
  • Creating a minimal agentic graph: a 'Hello workflow' example.

State, Memory, and Context Passing

  • Designing graph state and node interfaces.
  • Differentiating between short-term memory and persisted memory.
  • Managing context windows, summarization, and rehydration.

Branching Logic and Control Flow

  • Implementing conditional routing and multi-path decisions.
  • Handling retries, timeouts, and circuit breakers.
  • Utilizing fallbacks, dead-ends, and recovery nodes.

Tool Use and External Integrations

  • Consuming REST APIs and databases directly from the graph.
  • Performing structured output parsing and validation.

Retrieval-Augmented Agent Workflows

  • Strategies for document ingestion and chunking.
  • Utilizing embeddings and vector stores with ChromaDB.
  • Generating grounded responses with citations and safeguards.

Evaluation, Debugging, and Observability

  • Creating golden sets, conducting evaluations, and running regression tests.
  • Monitoring quality, safety, and cost/latency metrics.

Packaging and Delivery

  • Setting up FastAPI serving and managing dependencies.
  • Versioning graphs and implementing rollback strategies.
  • Developing operational playbooks and incident response plans.
