Agents shouldn't walk knowledge graphs: Use graph expansion tools instead
gimalay · reddit · 2026-09-01
Critiques the inefficiency of agents traversing knowledge graphs for memory due to high latency and noise. While flattening data for semantic search solves traversal cost, it loses structural context. The author proposes keeping the graph but moving traversal logic into a dedicated tool. A single command retrieves a node and its dependencies as one consolidated document, preserving structure while minimizing calls. This method, implemented in the open-source IWE tool (Rust), offers deterministic retrieval suitable for structured memory systems.
