## The Hook

LangGraph is the operating table for agents that need to loop, branch, and remember.

## What's Good

The graph-based approach finally makes agentic behavior tractable. You define nodes (actions), edges (transitions), and state schemas—then the framework handles persistence, streaming, and human-in-the-loop interrupts.

## The Catch

The abstraction overhead is real. Debugging graph execution requires understanding the underlying state management, and simple agents become verbose.

## Verdict

The right tool when agents need memory and branching logic.
