Someone asks <em>"Why did we choose Kafka over RabbitMQ?"</em>, and no one remembers because the engineer who made the call left six months ago.</p> <p>For the <strong>FalkorDB Graph Hacks Hackathon</strong>, we built <strong>NEXUS</strong>—an AI context engine that uses FalkorDB as a living company brain.</p> <h2> The Problem with Ordinary Agents </h2> <p>Standard AI agents rely on vector search over flat text files. But company knowledge is fundamentally a <strong>graph</strong>:</p> <ul> <li>People work on Projects</li> <li>People make Decisions</li> <li>Decisions reference Documents and supersede older Decisions</li> <li>Technologies have reverse dependency blast radiuses</li> </ul> <p>When an agent only has flat text, it hallucinates. When it has a graph, it follows real paths.</p> <h2> How FalkorDB Powers NEXUS </h2> <ol> <li> <strong>Multi-Hop Traversal</strong>: Translating natural questions into Cypher (<code>(Person)-[:MADE]-&gt;(Decision)-[:REFERENCES]-&gt;(Document)</code>).</li> <li> <strong>Decision Archaeology</strong>: Tracking superseded technologies with <code>[:SUPERSEDES]</code> edges so history is never lost.</li> <li> <strong>Cross-Session Agent Memory</strong>: Storing conversation sessions and episodic memory as graph nodes in FalkorDB.</li> <li> <strong>Autonomous Coordination</strong>: Agents write <code>:Handoff</code> nodes into FalkorDB to delegate tasks to other agents.</li> </ol> <p>Check out our open-source repo: <a href="https://github.com/Prasannaram2k4/nexus-falkordb" rel="noopener noreferrer">https://github.com/Prasannaram2k4/nexus-falkordb</a><br> Live demo: <a href="https://nexus-falkordb.onrender.com" rel="noopener noreferrer">https://nexus-falkordb.onrender.com</a></p> ai webdev programming productivity
