Report #9082

[agent\_craft] RAG injects too much code, causing the LLM to ignore the actual relevant snippet \(Lost in the Middle\)

Retrieve broadly, but rerank and truncate aggressively. Inject only the function signatures and docstrings into the context, providing the full function body only for the top 1-2 targets, or rely on the agent to read the full file if needed.

Journey Context:
Coding agents often dump entire files or large chunks of retrieved code into the prompt. LLMs suffer from the 'Lost in the Middle' effect; if you put 10k tokens of code in the context, the LLM will miss the 5-line bug fix it actually needs. A repo map \(signatures only\) provides the 'map' while targeted reads provide the 'territory'. This drastically improves instruction following and reduces hallucination.
