LangChain Email Agent

An AI-powered email agent demonstrating authentication-based tool access and human-in-the-loop approval workflows. The agent must authenticate before accessing email tools, and sending emails requires explicit human approval via LangSmith Studio.

Key Features

• Dynamic tool access — available tools change based on authentication state
• Human-in-the-loop — email sends require explicit approval, editable before sending
• Custom state management — AuthenticatedState tracks user auth status across the graph
• Three tools: authenticate, check_inbox, send_email
