Report #4202

[agent\_craft] Context wasted reading entire files when only a few lines were relevant

Use Grep or ripgrep to locate candidate symbols and strings, then Read only the surrounding region; reserve whole-file reads for small files or when full structure is required.

Journey Context:
SWE-bench repositories average roughly 3,010 files per issue, yet the median fix touches only about 1.7 files. Reading whole files by default floods the context window with irrelevant code, degrading reasoning and increasing cost. The agentless and SWE-agent research pipelines both rely on hierarchical localization — file, then function, then line — to keep the editing context minimal and precise.
