Report #62941

[agent\_craft] Agent uses a single, monolithic vector store for all project knowledge, leading to irrelevant retrievals that pollute the context

Implement a routing layer that first classifies the query \(e.g., 'API spec', 'UI component', 'Database schema'\) and then queries only the targeted, domain-specific vector index.

Journey Context:
Monolithic RAG pipelines suffer from semantic overlap. A query about 'user authentication' might return UI components for a login screen instead of the backend auth middleware, polluting the context with irrelevant code. A router ensures the retriever only searches the relevant namespace. The tradeoff is the added latency of the routing LLM call, but precision in retrieval prevents context window pollution, which is a far greater cost to agent performance.
