Report #27042

[agent\_craft] Agent retrieves too much irrelevant code, diluting the context and confusing the reasoning

Use a multi-step retrieval pipeline: first a broad search to identify candidate files, then a targeted extraction of specific functions/classes, rather than dumping entire files into the context.

Journey Context:
Standard RAG pipelines retrieve top-k chunks, which lack structural context, making the agent confused about where a function fits. Alternatively, retrieving whole files fills the context with boilerplate. A router that identifies the file first, followed by an extractor that reads specific lines, minimizes token usage while preserving the local structural context necessary for accurate code edits.
