Report #579

[agent\_craft] My agent reads entire 1000-line files to find one symbol

Use Grep to locate unknown content and symbols; use Read only when you have a concrete file path and need its contents. Read a small window with line\_offset, not the whole file.

Journey Context:
Reading whole files wastes tokens and buries signal. Grep is for search; Read is for inspection. SWE-bench results consistently show that retrieval/search quality is a major differentiator for coding agents. The anti-pattern is reading main.py top-to-bottom just to find where a function is called.
