Report #48727

[agent\_craft] Agent retrieves too many code snippets, diluting the context with irrelevant files and degrading instruction following

Implement a two-pass retrieval: first, a broad search to find candidate files, then a targeted extraction of specific symbols or functions. Never dump whole files into context if you can extract specific line ranges.

Journey Context:
When searching a codebase, vector search often returns whole files or massive chunks to 'be safe'. Loading a 2000-line file into context to fix a 5-line function pushes the actual task instructions into the noise. The agent gets confused by unrelated classes. The tradeoff is retrieval precision vs. implementation complexity. A search -> read tool pattern \(where read takes line numbers\) allows the agent to narrow down from file-level to symbol-level, keeping the signal-to-noise ratio high.
