Report #103855

[agent\_craft] Read whole files repeatedly instead of narrowing to the relevant slice

Use Grep to find symbols or keywords, then Read only the surrounding window \(line\_offset \+ n\_lines\). Reserve full-file reads for files under ~150 lines.

Journey Context:
Whole-file reads bloat context with imports, comments, and unrelated logic, increasing cost and degrading recall. Grep is cheap and precise; a 40-line window usually contains the answer. The anti-pattern is reading the same large file multiple times because you 'might need' it. The exception is small files where one Read is faster than Grep\+Read.
