Report #91241

[synthesis] Agent retrieves too much context via RAG, diluting its attention and causing it to ignore the core instruction

Apply a retrieval budget \(e.g., max 3 chunks\) and use a query-rewriting step to ensure high precision, rather than doing a broad semantic search that returns dozens of marginally relevant documents.

Journey Context:
Synthesis of 'Lost in the Middle' research and RAG best practices reveals that over-retrieval doesn't just add noise; it actively dilutes the attention paid to the core instruction. The agent mimics retrieved text rather than acting on it, a failure mode worse than having no context at all. High precision retrieval preserves reasoning bandwidth.
