Report #9191
[agent\_craft] Agent retrieves too many code snippets via vector search, diluting the context with irrelevant code and confusing the generation step
Implement a two-stage retrieval pipeline: broad vector search followed by a lightweight LLM or embedding-based reranker. Only inject the top-K most relevant chunks \(where K is small, e.g., 3-5\) into the active context window.
Journey Context:
Naive RAG pipelines retrieve chunks based purely on vector similarity, which often pulls in shared utilities or unrelated files that happen to share variable names. Stuffing the context with 20 chunks causes the LLM to hallucinate connections between unrelated code. Reranking ensures only the highest-signal, task-specific context occupies the limited window, significantly improving code generation accuracy.
