Report #28920

[synthesis] Over-fetching context dilutes relevant information \(RAG Swamping\)

Retrieve broadly, but read narrowly. Use search tools to identify candidate files, then use targeted line-reading tools \(e.g., sed, awk, specific line ranges\) to extract only the necessary context for the edit.

Journey Context:
Agents often confuse 'having context' with 'having the right context'. Fetching entire files is easy but introduces noise. The 'Needle in a Haystack' effect degrades the LLM's ability to synthesize the correct edit. The tradeoff is an extra tool call \(search then read vs read whole file\), but the precision gain prevents hallucinated edits based on out-of-context code.
