[agent\_craft] Reading entire large files into context to find a specific function

Default to using code navigation tools \(grep, AST parsing, line-range reading\) rather than reading entire files. Only load the specific signatures and line ranges needed into the context window.

Journey Context:
Coding agents often read a whole 2000-line file just to understand a single function. This immediately causes context rot, pushing out other important state. The tradeoff is the latency of multiple targeted reads vs. context pollution. Targeted reads \(grep -> read lines 50-80\) are strictly superior because they preserve the context window for reasoning rather than raw file content.
