[architecture] Agent fails to answer complex questions requiring connecting multiple disparate pieces of information across the codebase

Use iterative retrieval or graph-based memory \(Knowledge Graph\) instead of single-hop vector search. Allow the agent to query, read the result, and use it to formulate a subsequent query.

Journey Context:
A single vector query often retrieves a chunk that says 'Module A depends on Module B' but doesn't retrieve the code for Module B itself. Flat vector DBs cannot represent relational dependencies. Graph RAG or multi-hop agentic retrieval allows the agent to follow the dependency chain. The tradeoff is higher latency and token cost per multi-hop query, and the risk of the agent wandering off path, but it is strictly necessary for deep, multi-file reasoning where local context is insufficient.
