[agent\_craft] Loading entire large files into the context window to find a specific bug

Use search tools \(grep, ast-grep, ripgrep\) to locate the exact line numbers, then only load the relevant function or class \(e.g., lines 40-80\) into context, rather than the entire 1000-line file.

Journey Context:
Agents often default to reading whole files because it's simpler and guarantees the code is there. However, loading a massive file consumes context budget, dilutes attention, and causes 'context rot' where the actual bug is lost in the noise. The tradeoff is an extra tool call \(search\) vs context space. For files > 200 lines, the search-then-read pattern is strictly superior because it preserves the context window for reasoning rather than raw code storage.
