Report #39794

[agent\_craft] Agent loads entire large files into context to find a single function, wasting tokens and diluting attention

Use a two-step approach: first, use a search tool \(grep/AST\) to locate the target symbol/line numbers; second, load only the relevant snippet \(e.g., \+/- 50 lines\) into context. Only load full files if they are small \(<300 lines\) or if structural understanding is explicitly required.

Journey Context:
Loading full files seems easier and requires fewer tool calls, but causes context rot and high cost. Search-first is slightly more steps but keeps context lean. Structural understanding sometimes requires the full file, so don't ban it entirely, but default to search-and-snippet to preserve the context window for actual reasoning.
