I gave my agent a graph and it stopped guessing who owned what

RepoBrain was developed for the FalkorDB and WeMakeDevs Graph Hacks hackathon to eliminate AI guessing in codebase management. By utilizing a knowledge graph instead of vector chunks, the agent provides explainable answers by walking relationships between commits, pull requests, and design docs. This approach solves the problem of lost context and outdated wikis, allowing on-call engineers to accurately identify module owners and design rationales by connecting fragmented company knowledge into a structured graph.
