LangChain Agent Framework Integration

Description

Integrates LangChain to compose AI agents that use tools — search, calculator, database lookup, API call — to resolve customer requests autonomously. Agents can reason over multi-step problems and select the appropriate tool for each step.

Canonical use case

A travel company's AI agent uses LangChain tool calls to look up flight availability, check baggage policy from a knowledge base, and calculate rebooking fees before presenting options to the customer.
