Report #6218
[architecture] Agent fails to answer questions requiring linked facts like 'What was the bug I found in the module I wrote last Tuesday?' because a single vector search returns neither the module nor the bug
Implement a multi-step retrieval process or Graph-based memory \(Knowledge Graph\). First, retrieve the entity \('module written Tuesday'\), then retrieve associated memories linked to that entity \('bugs related to module X'\).
Journey Context:
Vector databases are great for single-hop semantic search but fail at relational queries. When memories are stored as independent chunks, the relationships between them \(e.g., 'Bug B is in Module A'\) are lost. Storing memories as nodes and edges in a Knowledge Graph allows the agent to traverse relationships. Alternatively, an agent can use an LLM to decompose a query into sub-queries and chain the retrievals. Graph RAG is the robust solution for complex, interdependent codebase knowledge.
