Report #24277

[agent\_craft] RAG pipeline injecting irrelevant code snippets that push out useful context and degrade instruction following

Rerank retrieved chunks and enforce a strict relevance threshold before injecting into the prompt; place the most critical retrieved context at the very beginning or end of the prompt.

Journey Context:
LLMs suffer from the 'Lost in the Middle' phenomenon where they ignore information placed in the middle of long contexts. Blindly injecting top-K RAG results dilutes the agent's focus and pushes the system prompt out of the attention window. Reranking and strategic placement maximizes signal-to-noise.
