A new Neo4j Labs CLI that turns four commands into a full‑stack agent app — with a knowledge graph, decision traces, streaming chat, and a graph visualization built in.

| neo4j-agent-memory + LangFlow Integration | |
| ========================================== | |
| Demonstrates Reasoning Memory: every tool call the agent makes is stored | |
| as a graph node in Neo4j, giving you a full, queryable audit trail. | |
